Blitz for Dummies

February 26, 2010

Blitz or flash freely translated into the flash. This is one accessory that is widely used in the world of photography. Its main function is to illuminate (mencahayai / illuminated) objects to the lack of light exposure well. But later began expanding its use to produce artistic photographs. However, flash photography is one thing to be learned. Most of the readers must have often used the flash well and getting good results also, but this paper will discuss the basic knowledge required to use the flash correctly. Correct in the sense in theory can be accepted and justified in terms of using a base that can be explained scientifically.

Using the flash is not merely a flash lit it, directing the camera and click and be a single photo and beautiful light, but there are things we need to know for the sake of getting good photographs and correct it. Whether we look at digital cameras as art or technology, the flash still is a means of simplify, optimize, and enhance creativity.

Meters, Aperture, and Shutter Speed

Photography briefly defined as the science is often painted with light. In conventional photography using film, we ‘paint’ with light in the film layer. Term is to burn the movie permanently using light with a certain intensity. The intensity of light entering the film or CCD / CMOS digital camera should be right. Excess lighting will cause the results of washed-out photos (commonly called over-exposure/OE) and lighting will cause the results of the dark images (commonly called under-exposure/UE). So how to get the right light?

We know what is called lightmeter in the world of photography. Lightmeter some built-in in the camera body and some are handheld. We usually use is the built-in lightmeter it. We use to measure lightmeter reflective light that comes into our lens (if TTL) and the processor will determine whether the camera is in accordance with the type of film cameras installed in us. In the auto mode or programmed auto, the camera will automatically find the right combination of f / stop and shutter speed (explanation follows). In the aperture priority mode (A / Av) the camera will use the f / stop which we select and determine the appropriate shutter speed. In contrast, the shutter speed priority mode (S / Tv) the camera will use a shutter speed that we choose and determine the appropriate aperture. In manual mode (M) we will have to determine the right combination is guided by the camera meter.

Aperture or shutter opening is wide hole opened by the camera to allow light inside. Usually symbolized by the number f / stop. This figure is actually the result of a multiple of sqrt (2). Commonly used is usually started from 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, ff. To keep in mind, the greater the number the smaller the opening. Because it is usually written as the denominator fractions such as f/1.4, f / 2, f/2.8, f / 4, f/5.6, f / 8, f/11, f/16, f/22, and so on. Aperture is also associated with DoF (Depth of Field) or the space that we can sharply defined as a room in front and back of objects that are included in the range of focus. DoF is itself influenced by 3 things are:

1. f / stop where f / greater DoF would provide a wider (more and more regional focus).
2. Distance of objects where objects are further focus will cause the DoF is also widening.
3. The use of telephoto lenses where the lens will give a narrower DoF than a wide angle lens (wide angle).

Shutter speed or aperture is the length of the shutter curtain is opened to allow light inside. This figure is symbolized by a second unit and the increase / decrease in the form of multiples of ½. Example: 30s, 15s, 8s, 4s, 2s, 1s, 1/2s, 1/4s, 1/8s, 1/15s, 1/30s, 1/60s, 1/125s, 1/250s, 1/500s, 1/1000s, 1/2000s, 1/4000s, and so on. The slower the light coming in more and more.

As measured by the camera’s meter the incoming light intensity is. If the meter shows the lack of light then we can reduce the f / stop or slow the shutter speed. Conversely if the meter shows the advantages of light then we can expand f / stop or speed up the shutter speed. One thing to remember is that the slower shutter speed the more likely the object blurred by hand movement, camera shake or movement of the object itself.

Blitz and GN

To divide / classify blitz, there are several classifications that can be used. The first, based on the availability of the camera flash is divided into the built-in flash and external. Built-in flash from the camera itself while the external flash is a flash attached additional cables or hot shoe to the camera. In addition, we also can divide by the type / brand of camera. We know the dedicated flash and non-dedicated flash. Dedicated flash flash is made specifically to use certain features within a specific camera. Usually the camera manufacturer-specific flash out also for the camera range and can use features such as TTL, slow sync or rear sync, etc.. While non-dedicated flash has the general functions of most of the camera alone and can be used regardless of the type / brand of camera. Flash this type usually require a lot of computation because the flash is already dedicated’ve got the information from the camera lighting so that does not require additional settings again. There are also flash output power (GN) can be arranged and some are not able to (fixed GN). We’ll tend to talk more about the flash non-dedicated, non-TTL, and fixed GN.

In using flash photography, we will not escape from the calculations related to the intensity of light reflected back from objects that we cahayai. Therefore, we will see what is often called the GN (Guide Number) or flash power. In short we can say if flashnya powerful, it will be one object with mencahayai lighter and can reach more distant objects.

GN is basically a simple calculation of flash power. There are 2 kinds of writing GN using a different calculation of unit m (meters) and feet (feet). Normally in Indonesia, we use the count to m. This is one of the considerations are also due to flash with the same strength, the number GN m and different feet away. In addition, GN is generally written for the use of film with ISO / ASA 100 and wide angle (35mm/24mm/20mm).

GN is a product of the distance from the opening (f / stop or aperture) in certain conditions (ISO / ASA 100/35mm/m or ISO / ASA 100/35mm/feet). For example, if we want to use flash to photograph a person standing at a distance of 5m from us using a 35mm lens and we want to use f/2.8 then we need to flash GN 14. Calculation commonly used is usually just find the right aperture for a particular blitz. For example, the GN 28 will flash to photograph the object is 5m that we will use f/5.6.

GN is only a guide for photographers. Not set in stone. Which affected a few. One of them is the ISO / ASA is used. Each 1-stop increase in ISO / ASA will cause GN increased by sqrt (2) or approximately 1.4 times (or the farthest distance multiplied by 1.4) and 2-stop improvement in ISO / ASA will cause GN increased 2 times (or the farthest distance multiplied by 2 ).

Film SLRs vs. Vs. Prosumer Digital Camera. DSLRs

One thing to remember is that the film cameras and digital camera is different. In the digital camera itself, there is a difference between pocket camera (in this case is usually able to use additional flash is the PDC / Prosumer Digital Camera)) and Digital SLR (DSLR). The first difference, of course, in terms of the proportions of the sensor / film to the lens. Because the digital camera sensor smaller than 35mm film, then we’ll be stuck on a long comparison of different lenses. To obtain a similar angle as 35mm, so the camera with a sensor 1/1.8 “will use the lens of about 7.5mm, D100 will use a 24mm lens and 10D will use a 20mm lens. This is the effective length of the lens to start the calculation using the flash GN.

Second, zooming. At the PDC, zooming will cause a change f / stop is slower (large numbers) and so also with the use of consumer zoom in SLR / DSLR. For example, we know f/3.3-f.5 lens 35-70. That is, the largest opening is f/3.3 at 35mm and the largest opening is f/4.5 at 70mm. This certainly will affect the object being photographed.

Use the zoom on the camera is usually coupled with the use of the flash zoom head. Telephoto lens / zoom to narrow the angle and zoom lens coverage on the flash head to narrow the dispersion of light that flash in other words increasing intensity, so they can reach further. Zoom head position and the telephoto lens on the wide positions would cause a part of the photo is not a light or familiar with the term vignet. Zoom head in wide positions and telephoto lens in position will cause a flash of light can not reach the remote object (after all, it’s worth a telephoto lens? For photographing objects that far?). In addition it also happens if we attach a 35mm lens on DSLR and then we do a flash calculation using the calculation remains to SLR is usually because the angle is equivalent to 50mm or more (depending on factors pengalinya). Actually there are no significant problems that arise, but we are ‘wasting’ the light in vain.


Most important part of a system is the lens on the camera

February 12, 2010

The quality of images produced by the first camera is determined by the factors of good lens, then the rest is processed by the sensor and image processor system in the camera. Unfortunately when someone is judging whether or not a camera, lens factor actually be the element that is often overlooked, as if each lens on the camera is the same. Someone will be more likely to pursue a high-resolution, high ISO capability and so on than to find out how well the lens contained in a camera.
No one did, because the resolution is a factor that can raise the prestige of a camera, and so the first thing that is always asked by everyone who saw our camera. But at least, to know how the lens is good and what keterbatasnnya, we can better understand the capabilities of our cameras.
For starters, let us first record the terms frequently used when discussing about the lens on the camera, so have the same perception about these terms.
• Focal length (focal length): Determining the image area that can be taken by the camera. To take a picture of a broad and wide, the lens used is wide lenses (below 35mm). To get a perspective of a normal image used normal lens (around 50mm) and take pictures for a much needed telephoto lenses (above 100mm). If the lens has only one focal distance lens just called fix (fixed), while if the lens can be changed from wide to telephoto zoom lens is called. Zoom lens capability is measured by comparing the maximum telephoto to wide maximum, for example when a zoom lens with wide focal length specification of 28mm and 280mm telephoto, it is called a 10x zoom lens (or 280 divided by 28).
• The speed of the lens (lens speed): Each lens has a diaphragm which regulate the amount of light duty that can pass through the lens. Diaphragm can enlarge and shrink according to the specified aperture value, expressed as f. For ease, remember that large openings have small f values, and vice versa (the small openings have a large f value). So f/3.5 is larger than f / 8. The bigger the lens opening, the more light that can be inserted through the lens, and allows use of shutter on the camera faster. Each lens has a maximum opening different, can be very large (f/1.4) to smaller (f / 4). Therefore, the lens has a large opening called fast lenses (can use shutter speed) and lens are small openings called the lens labih slow, because most often forcing the camera using a slower shutter.
• The sharpness of the lens (sharpness): Being a determining factor of a good photo results, usually no matter the sharpness of certain size, but by looking at test results of the review of the camera / lens to the test chart, we know the sharpness of a lens. A good lens ideally should provide a uniform sharpness throughout the image area, both in the middle or at the edge / corner. Similarly, the sharpness of the zoom lens, ideally should remain sharp both at the time when atapun wide maximum telephoto.
• Distortion lens (lens distortion): It is an optical aberration phenomenon that can not be avoided because the lens will tend to bend the straight image area, primarily as wide or telephoto position. Distortion at wide-called barrel distortion (straight lines become curved out) and at telephoto is called pincushion (straight lines become curved in). However, the present lenses have been equipped with specialized lens elements to reduce the lens defects that may occur.
• Another term commonly used in assessing the lens is vignetting, purple fringing, lens flares, and Bokeh. But on this occasion I will not discuss these terms further considering the limited time.

Before buying a camera, one should first recognize that the future needs of a photographic camera lenses in accordance with his needs. Here are some common scenarios that occur in the real world:
• For daily use, simple documentation photographs, family pictures: 3x zoom lens, with focal length 35mm to 105mm. This is the lens focal length is most common in compact cameras on the market. Wide to telephoto lens of this kind is considered to meet most of the photography needs everyday.
• For landscape and architecture: wide lens (fixed or zoom). For example, DP Sigma compact cameras have a fixed wide lens, while the other camera lens at wide can generally up to 10x optical zoom. For example, Lumix TZ4 has a focal length from 28mm to 280mm. On the market today began many cameras with wide lenses, though not always the same length fokalnya. Generally is at 28mm, although some are 30mm or even 24mm.
• For the needs of remote images, bird lovers, and who liked to secretly photographed from a distance: a telephoto lens which is generally found in cameras Prosumer / super zoom. Usually camera with telephoto lens has a maximum length of over 300mm, and some even above 500mm. If you find a camera with 10x optical zoom, 12x, 15x and even up to 20x zoom, the camera is an example of a telephoto lens capabilities.
• For the needs of high-shutter speed, or use in place of less light: fast lenses with diafrgama maximum exposure above f/2.8. Or a zoom lens that has a constant maximum diaphragm opening (as in the lens Lumix FZ20). Keep in mind that such a fast lens is quite rare, however, because the design is difficult and high production costs. Instead, now encountered a new camera with a slow lens with the diaphragm opening that starts from f/3.5 quite disappointing.
After a prospective buyer to understand the needs of photographic cameras and choose lenses (camera) that he liked, then he can explore further to the lens (camera) that has it. In practice, there will be so awe or disappointment may even be the performance of optical lenses. But once you do not feel sorry if the picture was not satisfactory, you can be too imposing your camera lens exceeds limits. At least, recognize the first few facts about the following lenses:
• The lens has many elements in it. The more elements, the path of light paths will become more complex and tends to reduce the quality and sharpness of the lens. So it has nothing in history can match the zoom lens fix lens sharpness, because of the many elements that have a zoom lens.
• The lens will always have a wide deviation / distortion. For that do not force a wide lenses to photograph people’s faces, because the later will look round and fat. Also avoid using a wide lens to photograph a straight line.
• The sharpness of the lens is not always the same. The sharpness of the lens is reduced when the diaphragm is opened up or reduced minimum (lens diffraction effects). A zoom lens will also decrease the sharpness when used in the tele position. To get the best sharpness, use a wide focal length up to normal, and use the diaphragm value of the middle (sweet spots) around f/5.6 to f / 8.
• The center of the lens is always sharper than the edge / corner. A good lens has a sharpness that still pretty good in his corner, and a bad lens will experience a severe reduction in sharpness in the corners, corner blurriness term. But considering most of the object image in the middle, then (thankfully) few people look at the corner detail of a photograph.
• The maximum diaphragm aperture on the zoom lens can be changed. To avoid the complicated lens designs, the zoom lens has its own uniqueness with maximum openings of different diaphragm in a different focal length. Notice the writing on the lens, ie lens 35-105mm f/2.8-4.5 means “the position of 35mm wide, maximum exposure is f/2.8, while at 105mm maximum telephoto position, opening up to f/4.5 maximum down”
• super zoom lens has a lot of compromise. Initially there is no lens that has an extreme focal range, which can accommodate up to 26mm wide on a 520mm telephoto lens. But the market needs and inter-brand competition makes producers finally forced to make a versatile lens can (sapujagad) such as the Olympus SP 570 with a 20x zoom. This kind of lens through a lot of theoretical limits of optical physics, at the expense of quality and sharpness, to meet the ambitions of a predicate all-in-one lens. In my opinion, a super zoom lens up to 12 x 10 is enough balance between capacity and quality telephoto, while the lens 15x, 18x and 20x seems too forced myself and only for those who are ambitious to have a very long lens.
Finally, let me give some feedback how to tips on selecting quality pocket camera lens. At least, for those of you who had intended to buy a pocket camera, can have an idea of how I rate the lens on the camera.
• Do not ambitious. There’s nothing wrong with a 3x zoom lens camera, though it would be nice to have a camera that can zoom lenses up to 6x or even more. Return to your needs alone, with the longer recognize the principle zoomnya, the more complicated elements of the lens, the more likely reduction in sharpness. If you want to buy a camera that zoomnya above 10x, make sure you have read reviewnya, see the sample pictures and feel satisfied with the sharpness of the lens.
• More wide better. This may be somewhat subjective, but believe me, it would be great to have a wide lens than a telephoto lens. In some cases, you can try extra to get the photograph as a telephoto lens (as closer to the object or cropping), but to get results that seem broad picture (and dramatically) can only be done using a wide lens. Find the camera lens starting from 28mm wide and at least telenya ends in 85mm.
• The sooner the better. Very simple, avoid maximum lens opening is smaller than f/2.8. When your camera has a slower lens, you will often raise the ISO and will result in a lot of noise in images. To that note written on the lens, which tells us how the maximum exposure. For example, relatively fast lens is like this: f/2.7-3.5 (the Canon S5 IS). Unfortunately, many camera manufacturers are not gentle with no writing on the specification maximum diaframa lenses, such as Kodak, Pentax and Samsung. So if you are offered f/3.5-5.6 lens camera, you can just say: no.
• Much better bonuses. Some elements of the lens given special bonuses such as optical stabilizer, lens and lens Asperical low dispersion. This bonus can reduce the distortion, purple fringing prevent and maintain the contrast and sharpness. Unfortunately the lens with low dispersion element bonus is rather rare (in some Nikon Coolpix line of cameras, lenses are marked with the code indicating a bonus ED low dispersion elements).

‘why professional photographers have to spend big money to have a full frame DSLR camera this expensive? “
I can only imagine what a full frame DSLR camera can only guess it, about what makes the professionals choose Full frame. Perhaps this is her answer:
• Noise cleaner at high ISO. Although ordinary DSLR capable of giving good results in photo high ISO, it does not mean necessarily without noise. For comparison the Nikon DX class, the lowest caste (Nikon D40) and the highest caste (Nikon D300) using the same size sensor so the noise in the case of high ISO would be the same. It could be at high ISO, D300 noise reduction approach is better, so look cleaner than the D40. But when pitted against the D700 for example, looks D300 is still oversized at high ISO. Professionals do not compromise with the noise.
• Without the crop factor. The main enemy is the wide lens crop factor of the sensor, so the lens should be very wide in 18mm would be 28mm when mounted on the ordinary DSLR camera. Crop factor might be a friend of a telephoto lens, but for the wide lens manufacturers have to think extra hard to make a fixed wide lens wide when exposed to the crop factor. Therefore, the present wide lens starts from 10mm to 14mm to get the angle of view is desired. With Full frame DSLR, 24mm lens will still 24mm. 18mm lens will remain 18mm, so very suitable for landscape photography.
• Dynamic range is better. With the large sensor size, pixel density and pixel size so that even greater ability to capture light sensor in any better. Full frame sensors can avoid the possibility of blown highlights or dark shadows. To maintain the dynamic range while the high contrast, professionals need Full frame DSLR.
• extra large Viewfinder. Imagine doing manual focus using the viewfinder small and narrow. It must be frustrating right? For Full frame DSLR that comes with a large viewfinder for convenient shooting object image.
Of course, many other answers, but the technique of the four factors above it deserves to be the main reason. If you feel it the four factors above can not be compromised, then you need a full frame DSLR. But keep in mind, Full frame DSLR does not mean much superior in terms of speed auto focus, metering and overall performance (fps, shutter lag, etc.) than usual DSLR. And when used at low ISO, the photographs of the two types of DSLR camera is very difficult to distinguish. So, wants to play Full frame DSLR or DSLR ordinary (APS-C sensor or sensors Four Thirds)? It’s up to you (and your budget of course).

Figures Diaphragm

February 9, 2010

Confused where the numbers “magically” come to the diaphragm bracelet? Here is an explanation
One of the basic theory of photography mentioned that every time down the diaphragm opening one-stop, means reducing the volume of light (which entered through the lens) as much as half. Conversely, if we widen the opening of the diaphragm one-stop, means increasing the volume of light as much as twice before. The explanation is as follows
Figures obtained from the ratio of the diaphragm between the lens focal length and diameter of the lens surface that serves to collect light. (f / stop = F / Ø)

So, if the lens has a diameter of 50 mm (diameter = diameter of the lens (glass) rather than the diameter of the filter holder) width of 50 mm it is said he has a diaphragm f / 1 (50 mm: 50 mm). This is a very powerful lens collects light and is currently only one manufacturer produced by the camera (canon).
From here can be calculated – using a normal lens with a maximum opening of f / 1.4 – how much the lens diameter is used to collect light.
50 mm: f / 1.4 = 35.7 mm
(rounding of 35.7142857 …….)²²
When we realize that the light is responsible for collecting the entire lens surface area in question, these calculations become more attractive again. Junior still remembers the lessons that the formula to find the area of a circle is equal to πr ² (pi r squared)? Or 22 / 7 times the radius times the radius?
So, if the radius of the lens diameter 50 mm f / 1.4 is 17.85 mm (35.7: 2) then the surface area of the lens is
π x 17.85 ²
= 3.1415926535897932384626433832795 x 318.6225
= 1000.982105268413896122063591389 mm ² (rounded to 1001 mm ²)
If we reduce the diaphragm one stop to f / 2, kemampua cahya from lens collecting the relevant be down by half. With the diaphragm f / 2, the lens diameter virtually had “changed” to 25 mm (50 mm: f / 2). The radius of the lens becomes 12.5 mm
Surface area (virtual) lens in question becomes
π x 12.5 ²
= 3.1415926535897932384626433832795 x 156.25
= 490.87385212340519350978802863742 mm ² (rounded to 491 mm ²)
Why not be half? 491 mm ² Does not have half of the 1001 mm ²?
Keep in mind that in photography there are a lot of rounding and compromise. 491 mm ² numbers are very close to half of the 1000 mm ². Besides differences in 9 mm ² area will be very little difference in the results of shooting.
However, if you are still curious, too, we see just why are not actually made half (500 mm ²). If so, we count back to
500 mm ²: π
= 500: 3.1415926535897932384626433832795
= 159.15494309189533576888376337251
159.15494309189533576888376337251 is the root of the radius of the lens, ie 12.615662610100800241235747611828 mm

From here to get the numbers as 25.231325220201600482471495223657 mm diameter. f / stop lens in question is
50 mm: 25.231325220201600482471495223657
= F / 1.9816636488030055066725143825606

The question now is, these numbers muatkah series to be written on the band width diaphragm that cute? Moreover is not it very obvious now that the actual f / 1.98, and so it was very close to f / 2?

We continue with the following diaphragm opening, which is f / 2.8 as well to show more about rounding and compromise earlier.

Virtual diameter 50 mm lens at f / 2.8 is
50mm f / 2.8 = 17.85 mm
(from 17.857142857142857142857142857143)
Radius is 17.85: 2 = 8.925 mm

Surface area:
π x 8.925 ²
= 3.1415926535897932384626433832795 x 79.655625
= 250.2455263171034740305158978472 mm ²
Or 250 mm ². Uhapir half of the previous surface area and a quarter of the area on the diaphragm permyukaan f / 1.4.

With this formula, the surface area of f / 4 is
122.71846303085129837744700715936 mm ² (rounded to 123 mm ² once again almost half of previous)

Surface area of the lens from one diaphragm to the other diaphragm less than half the range (if reduced) or twice (if raised) from the previous value.
In conjunction with shutter speed, seems clear enough that by reducing the volume of the light half (-1 stop) automatically takes twice as long (+1 stop), and vice versa, by doubling the volume of light, the time needed also becomes more rapid two – fold.

Then, do you know that there are several versions of the true meaning of the f / stop? F / stop (small f) can mean one below.
a. abbreviation of fenestra (Latin) which means “window” (interpreted as the opening of diaphragm forming a “window” for cahya to enter through the lens).
b. Abbreviations of the function (function) or fraction (fractional)
c. The symbol of the focal length (focal length) divided by the diameter of the opening (aperture)
d. From a legendary photographers (Ansel Adams) who was the form of the letter ‘f’ for the opening of the diaphragm more “beautiful” and “artistic” American standard of writing that had popular in the early 20th-century ago (eg, U.S. 1 to f / 4, US4 to f / 8, and so on).

Whichever you believe, he explained the word “stop” represents a shift of the diaphragm into the diaphragm opening of others who have stopped at the point of control bracelet.

Revealing the Secret Photo Excellent
This paper is an adaptation of an article in photosecrets.com, I like it and prefer to read them in their own language, with its own style. At first I was published in the forum thread, but for the common weal I move them to page the article. Hopefully useful, especially for me and other beginners, and for the senior pictures are fine of course, I’m sorry, because some of your secrets become common knowledge. But of course, without training and persistent effort, this article will only be used to true stories we read in the newspaper.

We have a friend named photography, the perfect friend in travel, service to the area, pilgrimage, picnic, going home or climbing the hill. Photography makes us confident that we explore the places visited, people we meet; photography make a more meaningful way, and we enjoy the fun with her love of art. Photography makes us more grateful for the gift of sight and the chance to see the signs of divine majesty. Pleasure that can not be measured and measuring.

Photography became a strong reason for our activities, go visit various places previously had no plans, come home late, buy equipment, and so on. Burning desire to get a steady shooting pains encourages us explore a place through the bushes, turning what would mutari we take pictures, searching to find the angle of the unique and unforgettable beauty, sometimes the search is also at risk of fatal if not done with caution and calculation logic.

Finding the best viewpoint is perisitiwa big, your heart beating, while you look at him with eyes shining, you might think, is this the right time to take a picture, you may be setting up camp and waited for the best moment from time to time, from dawn till Asar, from March until December. You become a resilient and patient.

When you press the shutter release, you tie a braided sweet person with a place and its people. You are there. Photographic memory protect your encounter with what is in it. Then we show to others about places and exciting atmosphere in which we had there, majestic scenery, the people are amazing. Your soul was drawn.

The pictures like affect our minds, like teasing us, forcing us to play in it or imagining it. The photographs that we create can encourage others to want to experience the beauty or the fun that presented the image. Of course, the beautiful landscape photos and the sexy model will generate the desire and imagination are different. Desire that arises unconsciously.

Anyone can become a member fotografer.net. That means anyone can take pictures. With the addition of creative thought and effort do not know falls, you can create great images that show your creations and interpretations of what you see and snap. Indeed the velocity and acceleration of the achievement of each person is different, one could be overtaken another, but not what was reasonable. Do not upset.

Fortunately, the good do not need expensive, good photographs can be made with minimal equipment and little knowledge of technical data. The secret is to look at the artistic and critical. The art of seeing. Bisikanlah this question in the heart: What I see, and how I see it? A good photograph has qualities that demonstrate the skills, artistry, attraction, and the personality of the photographer. So we can know what a good picture. But can not know what a bad picture, ask why?

What Makes a Good Photo?
Good photographs are images that contain messages. The message can include a statement (This is Lake Toba), impression (Dusk atmosphere in Lake Toba), or expressions of emotion (Love in Lake Toba). Messages bagusadalah clear message, firmly and effectively. But how?
The message needs a subject. About what you want to convey. That might be one that you know, landscape, or abstract forms. The subject is the center of the POI and are usually placed in the foreground. Then we set the message by entering the second part, namely context, often the background. Context provides relevance, the existence, location, subject, or other interests. The message is a combination of two elements of the subject and context, foreground and background narrating the message.

As the importance of knowing what needs to be inserted into the message, we also need to know what you do not need to be incorporated into the message. Apasaja that are not part of the subject or context of the message that we make, then it is just a thorn or glass annoying, scratching pictures and make our message becomes unclear. So cut the parts that are not relevant in some POI usually with inching closer to the subject, or move to get a better viewpoint and make shots clear and clean. A painter creates art with the addition of adding what he painted as a photographer to create art with a reduction reduces the parts that do not need.

Recipe for a good photograph is:
“A foreground, a background, and nothing else.”

What Makes a Great Photo?

Great photos directly stunning eyes. While the proverb says: picture may say a thousand words, then the extraordinary photos only say one word: Wow!

A great photograph is a work of art. It captures the spirit of the subject and evokes emotion. Bob Krist called The Spirit of Place. You can also use tricks to make palpable awe visitors your photo gallery. Let’s see how.

A picture is a playground, there are places where our eyes wander and watch, also the space where our eyes to rest and relax. When we first see something, we act to not be affected. Our eyes are naturally found a light, bright areas, and find people, usually in the eyes and mouth. Do we know the people in the picture? What they feel and how does this relate to us? Are they drawing attention to something? If so, whether we recognize it (a building, a landmark) and what he? About whether these pictures? What main subject or objective? How big is the subject? We determine the scale by comparing elements with something that we know sizes, such as people, animals, or cars. Once we finished watching people and elements related, we continue our attention to elements that more abstract.

First we look at the color or tone of the subject. Red hot, cool, distant blue, natural green, black silence. Then we see the shape. Gentle curves, tight corners, the lines that sweep. How light on the subject provides subtle shadows of three-dimensional shapes. You, as a photographer, can manipulate it all by looking for light and dark, shifting the intensity of tone and hue. How the eye drawn into the picture?

Guide us in the form of texture, how the subject feels the touch. He Lembutkah, haluskah it, hard or rough? Would have character and warmth? The way the elements are juxtaposed and are influenced by the same light, makes us consider their quality and relevance. This balance leads our eye from one element to another element, investigating its unity, contrast, and detail, each item to add fun to the next item. What relation to one another of all that?

As an artist, you are faced with choices that will reveal the sense of the art you. Composition as a whole, the proportion of layout, presentation of other elements are important, you can determine which features you need, and what is best to emphasize your message.

Recipe for great photos are:
Consider how the elements related overall.

What Makes Photo Eye-Catching?

Back to the eye-catching nature of extraordinary photographs, along with his secret, just 4 keys: simplicity, color, light and depth.

Simplicity: Simplicity in art is also known as the visual economy, which eliminates all the elements or details that do not need that there is no contribution to the spirit of the composition as a whole.

Simplicity can be achieved in several ways:
• reduce the number and type of object to be targeted
• photographing closer to the subject, or if the lens can zoom in, zoom
• You can also remove elements that do not need to go through the path photoshop

Color: To create an impact on your photographs is to find a prominent color patterns. Red flowers, blue sky, sunset yellow, or green leaves. Once again, simplicity is the key to try to reduce the number and type of color in your shots for better impact. In general, a photograph should have only one main subject and one main color. Concentrate on only one of the three primary colors: red, blue or yellow. Three dominant color is very good balanced by its complement colors, namely red with green, blue with orange, and yellow with purple.
There are several ways to highlight the color, the first is to use a polarizer filter. The second way to limit the range of dark to light. Get rid of areas that are too dark or too light compared to your main subject. The third way by using Velvia slide film. The fourth way: select the best time in accordance with the purpose of your photographs:
5 hours: Morning: pink, light a very smooth and light mist to lakes, rivers and scenery.

6 hours: Sunrise: Light crispy, golden. Fit for subjects facing the east.

10 hrs 14: Middle-day: not suitable for the scene and pictures of people, but good for pictures of buildings and monuments. The colors and detail of the building is very well documented.

14 hrs 16: In the afternoon: blue sky with a polarizer.

16 hrs 18: Dusk Day: Light a warm, golden. Fit subjects facing west. The best time for landscape and people, especially one hour before sunset.

18 18:30 hours: Sunset: The sky is beautiful, starting 10 minutes before sunset until 10 minutes later.

18:30 hrs 19:30: Sunset: Photo of a beautiful night, the lights were still bernyalaan while the sky looked purple.

Light: good lighting is often the key to championship photos. The use of daylight can also effectively improve your photos. To achieve such beautiful pictures in National Geographic, Photo capture the golden light appeared after sunrise and before sunset, often called the magic hours of the photographer. Let’s see more details of the best times over.

Depth: Include a sense of depth to your picture. The depth can be achieved by DOF settings, placement of elements in the photograph, and lighting. Exposure, exposure / lighting are: the number of rays received by the sensor / film. If less light so the image tends to look dark / under, while what if excess of the photos will look tends description / over …
Lighting itself is a combination of AV / aperture value that is the size of the diaphragm, TV / time value / shutter speed of the shutter opening duration, and the last ISO / iternasional standards organization which in this case is an international standard for the sensitivity level sensor / film …
This exposure alone is often not as dianalogi we want to fill the glass with water from the tap … Where is the tap rotation compared with the aperture, while the tap is opened compared with the shutter speed, compared with the ISO glass, water pressure compared with the intensity of illumination (light or low light), and finally water compared with the light … So if the faucet wide open so we’ll quickly full glass … While we tap kecilin reply then the glass will be longer completely … And when we pake large glass (low-iso) then we will also be longer to fill the glass, unlike if we kecilin glass (high iso) so the glass would be full faster … But still large digelas water more than that in a small glass … Similarly, the water pressure, the higher the water pressure (bright light conditions), or the smaller the water pressure (low light) will affect the charging time … But sometimes before we have a full glass of tap it happens to hail a state under … Or just the opposite even though the glass is full but we are closing the tap belom the situation over there …
Ease today this exposure was calculated automatically by the camera with a name metering system. It works like Matering light / flash meters. The difference in this system can measure continuous light just … And another advantage is the technology now we can analyze the image from the histogram on camera … While ancient kalo a photographer must carry a bundle of records containing such things as photographs reply av broad daylight, tv, how the iso it all, there are clouds continue to reply so many, many reply that afternoon, and so on …
Now working principle of this metering determines exposure itself is gray 18% (according to the gray card) in a lighting condition … So when we photographed the object or situation the dominant white / light / hi key abu-abu/gelap will look at our photos, and when we photographed the dominant object in black / dark / low key will also be seen a gray / at our pictures are brighter than actual circumstances … And hence we have the camera exposure compensation (in the two-digit class number -2 to 2).
And conclusions also reply to a picture with the right exposure (exposure corect) yes measuring / metering is on the gray card placed on the lighting would we measure exposurenya …
And one more if the contras between where the most dark or bright cause has not caught again Full Story at dark or bright places are, then you have to choose between being on the exposure or sacrifice one of them (keep in the shadows Story or at the light). .. Sukur-sukur not reply vast dark place and we can lift the (fill in) with artificial illumination such as flash …
At the time, high contrast is needed dynamic range camera with a wide range or use the usual editing techniques we call HDR …
Return to the components of the exposure:

a. Aperture
Aperture has the following rates (for shift 1 stop): … 1; 1.4; 2; 2.8; 4; 5.6; 8; 11; 16; 22; 32; …
Numbers above mean itself is an open hole on the lens we like (number above) from the broad lens of our … That need to be seen how the aperture affects our image that is more wide open aperture (small number) the more narrower / shorter DOF / space we get a sharp … And the narrower the hole (large number) it will get longer DOF / space we get a sharp …
Regarding input from oom Kana Lay there is a theory that a lens that will record a maximum of lenses in the subject when aperturnya set about 3 stops from the aperture is narrower broadest … Example: if the lens with the widest opening 2.8; terbeningnya the images will be found in the opening 8 …

b. Shutter Speed
There are also numbers on the shutter speed is as follows (for a shift in one stop): … 8000, 4000, 2000, 1000, 500, 250, 125, 60, 30, 15, 8, 4, 0’5, 1 ‘, 2 ‘, 4′, 8 ‘, 15′, 30 ‘, bulb (for a camera shutter button to continue recording) … Numbers above mean itself is like (number above) seconds and seconds to sign ‘. That need to be seen how speed affects our image that is: with a high speed moving subject (particularly silence) will look frozen, so look sharp … While in low speed motion (movement) of the moving subject will also be recorded by the camera … And if dilamakan again at a certain time moving object will not be recorded by the camera at all (not present in the photo) …
Now to determine their own speed so that our image freze (frozen) and a sharp two things to consider:

b1. Minimum speed to freeze subject motion (subject motion)
Basically the various levels of shutter speed to freeze the subject … This is strongly influenced by the speed of the subject itself … As the reply was photographed pause (poses) with 0.5 seconds may still frozen … But the speed of the frozen much for reply belom street person … Between the road and running speed is also different for the freeze … Movement on the stage may be frozen at the speed 1/125dtk … But maybe could freeze belom street bike … So it is with people who are racing course should be even faster speed to freeze … But apart from the speed of the subject itself, there are other things also affect the subject distance and direction of our movement … The closer the subject the more rapid the movement … This is why aircraft fly so fast but it seemed slow when the sky … Because distance emang far … Kalo sabject direction of movement toward or away from us will be different from the speed when moving parallel to the sisubject our view …

b2. Minimum speed the capture of hands held way (by holding the camera without a pedestal or tripot)
In principle, the long focal length the more we use it will be more easy movement on our camera, which will take recorded on the photo … Held hands eating this formula associated with the long focal length that is speed = 1 / (long focal length)
Well this is where the IS (image stabilizer) was very influential … IS my own prisipnya by analogy with Shockbreaker the car … Technology serves to reduce vibration happens … Maybe that is often a question where the hell IS bagusan on what lens to the body … Kalo my personal opinion, the same analogy as a shock to move from a motor under the seat to be near the wheel … Quencher placed closer to the source of more efficient work … Yes of course IS the better lens for more light first movement into the new lens forwarded to the sensor … But IS also has limitations in reducing the vibration …
So while speed is too slow that we should use tripot … Actually there are two tripot function, which I will explain only part focusing on … Satuhal that needs to remember, turn off IS if you take pictures using tripot

That should be emphasized here:
- IS and Tripot only to dampen vibration on camera … But not to freeze the subject …
- Not all photos have to freeze it, because there are some pictures that are beautiful if we use such a low speed stream photographed to look like cotton, photographing the car lights are there in the street, and even in the action stage also will be more beautiful if slightly motionnya caught.
- There are even pictures of where the camera techniques deliberately shaken at low speed …

c. ISO
Figures from the ISO itself is (for a change 1 stop): … 50, 100, 200, 400, 800, 1600, 3200, 6400, … The higher the ISO number the more sensitive the sensor / film when exposed to light … I need to know how the ISO affects our image, namely: higher iso will likely cause more image noise, less contrast, less resolution …

A little addition to the figures above related to the stop is as follows: when you take a picture with the exposure speed 60, the diaphragm 8, and ISO 100 … Apparently you think your subject is less frozen and decided to raise the speed to 125 (1 stop) … To get the exposure value (the same light dark in the photo) then you have to expand your diaphragm opening to 5.6 (from 8 to 5.6 = 1 stop) or you should increase your iso to 200 (up 1 stop) … Well this is the technical factors that make each photographer’s photos of different … In certain circumstances there are photographers who prefer to sacrifice speed, there is a sacrifice ruangtajam, and there is more tolerance for noise is the picture of them …
Well this is where you will decide to use the mode where the creative zone … Kalo your priorities in the diaphragm for example because you want to get a stable dof use AV mode because your aperture will always remain, and your speed will automatically look for camera … But your reply on priorities such as speed subjectnya want to be frozen, use the tv mode because your speed will always remain while the aperture will be determined automatically by the camera … Kalo fixed which occurred on Stelan TV example, you specify you want to take on speed 125 … figure your exposure on camera metering and 2.8 show the number you are using a lens with f terlebarnya maximal 2.8. Then the numbers flashing, it indicates the level of iso you’re using it, although still under the automatic setting is resolved by the camera (in this aperture) is the maximum … Means you must raise the ISO to aperturnya not blink again so that you get the exposure right … Normally when you blink reply forced to take pictures without changing the ISO, it will adjust itself speednya which in this case to a lower speed if you’re using tv mode …
O it, if you doubt terhadapa exposure value you want it, it’s good you do braketing (AEB = auto exposure baketing) … That is a facility of the camera where the three frames that we will have pictures under the size, the right size according to camera, and size over … How stop under and we can overnya stel … So every subject we have a portrait photograph of three times, and we’ll get three photos with different exposure … How to settingnya: menu -> AEB -> Set -> quick control dial (to determine how stopnya) -> set.

Photography Major


The link between ISO and noise in digital photography

February 5, 2010

For starters, just so-so recalled that the basic photography is to play with light, which more or less light is captured by the camera is influenced by how the shutter speed and size of diaphragm opening. In the era of film photography is known as ASA score indicating the sensitivity of the film the film to light. The term ISO in digital photography (referring to the ISO 12232 standard) such as ASA was equivalent to the film, which in this case the value stated ISO sensitivity sensors in digital cameras.

CCD sensor
Sensor, whether CCD or CMOS, is a major component of a digital camera, which is a piece of silicon chip composed of millions of light-sensitive pixels. At the time the picture comes from the lens of the sensor each pixel will capture light energy to come and turn it into a voltage signal magnitude. How sensitive sensor capable of capturing light that is expressed by the ISO scale. Each sensor has a base ISO values / normal ISO sensitivity is the lowest value of the censor is generally equivalent to ISO50 to ISO200 (depending on type and brand of camera). On the value of this normal ISO sensitivity to light sensor is at the lowest level that is needed enough light to get a photo with the right exposure. Therefore the normal ISO generally used only when shooting outdoors in daylight.
To measure the light, call metering, the camera has a light meter system (light meter) that tells how much light will enter the sensor. If the light received by the sensor is too low (sometimes the camera gives warning in low light the LCD screen) then the option exists to keep exposure is to increase the diaphragm, slow shutter, and / or increase the ISO value. In compact cameras are all automatic, shutter and diaphragm value will be determined automatically by the camera based on the results of light measurements. If the condition is less light the shutter and diaphragm combination could not produce the proper exposure, then the ISO value should be increased. If the ISO on the camera mode is set to AUTO, the camera will increase the ISO value automatically. At that allows the camera to be set manually the ISO value, the value of a higher ISO can we choose in multiples of factors ranging from 200, 400, 800, 1600 to 3200. Even now the latest digital cameras began to offer the ability to ISO 6400 extra high sensitivity.
It should be noted that the value of a higher ISO also allows shooting with a shutter speed faster. This is because the high ISO to give a high sensitivity so the camera does not require much light to get proper exposure. Shutter speed is useful to make a moving object appears to be silent. Term, freezing objects (see comparison picture at right). Use a low ISO (eg ISO 100) will make the shutter is fast enough (eg 1 / 20 seconds) to be able to capture the child’s movements. By raising the ISO (eg ISO 800), obtained the value of a faster shutter (eg 1 / 160 second) so that the child was still visible. Sometimes the camera is not equipped with stabilizers, the use of high ISO can also be utilized to prevent a blurry picture. With high ISO is expected to hand-shake is usually prone to motion blur can be avoided because of a faster shutter.
Unfortunately increasing the ISO will also bring negative effects of unwanted. Increasing the ISO sensitivity of the sensor is increased, so that weak signals can be strong. The problem is, the sensors work processes also generate noise that accompanied the original signal. If the ISO is increased, the small initial noise will also be a high. High noise would disturb the results appear and appear in the form of image dots of color are not good to see. These noise problems are more severe if the type of sensor used is a small sensor, such as commonly used in compact cameras. Why? Because of the small sensor size point / pixel is also smaller, and smaller pixels theoretically more susceptible to noise than larger pixels. Hence digital SLR camera produced better images at high ISO, because the DSLR camera sensor using a larger (and more expensive production costs).

Noise on the various types of cameras
What can be done to overcome the noise? First of course as much as possible avoid the use of the ISO too high. But if forced use high ISO, digital cameras today have a noise-reducing system (Noise Reduction / NR) which automatically tries to refine the results before saving the image into a file. Each brand has a camera ‘approach’ for this to overcome the noise. A trademark can be applied to a NR so that the image looks still a little noise but have better detail. Brand B could be used NR too much so that it generates images free of noise but the details go missing. Unfortunately until now there has been no method of NR is able to eliminate noise while preserving detail but with equally good photos. If it needs a lot of making photographic images using a high ISO, you should use a professional camera with a large sensor (2 / 3 inches, APS-C or even Full Frame) which has Signal to Noise ratio is good, so the effect of this noise can be reduced.
Conclusion
• The value of ISO in digital photography states that the sensitivity of the sensors used in digital cameras.

• If the shutter and diaphragm settings still can not get the right exposure (usually in low light conditions) then it could try to raise the ISO value.
• In addition to shooting at low light, high ISO usage is also suitable to prevent hand-shake blur effect (if the camera does not feature stabilizer) or for high-speed photography, because the high ISO allows the use of faster shutter than a low ISO.
• Raising the ISO value will make the side effects of noise on the image.
• Method Noise Reduction (NR) can be used to reduce the noise that comes up, but ideally the NR still able to maintain detailed as possible so that images remain sharp.
Advice
• Find a camera that has a larger sensor than the camera in general, so the effect of this noise can be reduced.
• Allowing the ISO mode in the AUTO position may be able to make automatic camera raises the ISO value is too high when used in place of the less light, the alternative arrange the ISO value is adjusted manually with the shooting conditions.
• When to use a high ISO, if available, use the RAW file format so that noise reduction can be done in software

Selling Photography to Magazine

through a PC.
• Do not buy a digital camera:
1. can not manually set the ISO
2. wearing false image stabilizer by increasing the ISO
3. has a higher megapixel sensor but the small size -> will be very noise at high ISO


Digital Camera Tips: Prevent Exposure Under Saku On Camera

February 4, 2010

Pocket camera users are complaining because the indoor photos that they tend to get less light (under exposure). This often happens in cameras that rely on built-in flash with range (coverage) plus a limited area to practice shooting at a maximum distance range of flash.

What often happens is:
1. At wide angle lens (zoom out max), only the central region bright enough pot, while at the edge / corner, tend to be dark, this occurs due to the limited coverage area of flash.

2. At telephoto lens (zoom in max), the overall picture tends to be less bright (under) because the light flash was not strong. This is due to reduced coverage due to flash a smaller aperture opening when zooming in done.

To avoid this problem, we need to know the capabilities built-in flash on the camera. In compact cameras, are generally only given a maximum range of data from the built-in flashnya, for example: at ISO 100 with the condition of wide-angle coverage of built-inflash is 3m, while the telephoto condition is reduced to 2m distance. This distance changes, increases or decreases in proportion to the ISO used. For example, the increase in 1 stop / double (ISO 200), the distance is increased ¼ time. At 2 stop / quadruple (ISO 400), 2nd time the distance increases. Conversely, if reduced to ISO 50, 0.7 time the distance decreases.

To prevent under exposure, try to take pictures in the distance before / under max flash range.
There are a few things must be considered in order to reply the resulting images are not under exposure, namely:
• Use the highest ISO the camera to take pictures in less light conditions (low light) and / or for fast-moving objects (photos sport / action). However, the use of high ISO on a pocket camera generally small bersensor will cause noise (in an analog camera or a camera that uses film is grainy) due to increased sensitivity of the camera sensor to light. However, these noise levels are still worth printing for small size (3-4R), if you are “allergic” to the noise, avoid ISO 400, ISO use ISO 200 as the highest.

• Use a flash with a low speed (slow synch flash) to the object and background tercahayai quite well. The use of flash with the low speed is particularly useful for taking pictures at night (night shoot / scene). But keep in mind, because it uses a low speed, the camera and photograph the object must still did not move and are advised to use a tripod to prevent photos of vibration due to hand shake. The lower speednya, the more natural color of the original light recorded (for example, light colors are more warm incandescent). Use the value of (+) EV (Exposure Value) to “enlighten” the photographs taken. Advantage of using the (+) EV is increased brightness that is not accompanied by an increase in noise due to the way it works is to decrease speed to the limit “safe” (speed limit is high enough for handheld). If it still feels not enough, then the next action is to enlarge the aperture. Related to how it works, there are some things that must be considered / calculated at the time of the shooting done:
1. The greater the value of (+) EV, the lower its speed. This is not suitable for making objects move (not to “freeze” objects), but more suitable for still images. When it comes to his enlarged aperture, the DoF would be shortened. But this is rare, especially considering the digital compact cameras have a DoF is “very” long, except for the macro picture. “Because the brightness of our deliberately” add “, so to avoid the use of close range shooting (close-up) are shooting distance 1m or dengahn less. In order not to over exposure (picture is too bright due to excessive light) better coverage of the object is approaching its maximum flash.

2. How much value (+) EV her? depending on how bright image we want, lighting conditions at the location shooting, and do not forget to adjust with the ISO setting that we use. There is a good idea to experiment first to determine its value.

Generally, the value of +2 / 3 – 1 (+0.7 – 1.0) at ISO 100-200 is enough. In certain conditions which require a high brightness level, maybe just enough at ISO 400 (eg: photo group had carried out the reply max flash range).

What about auto ISO? consider his ISO range, generally between 100-200, 100-400, 50-150, depending on the brand / type of camera (though the camera generally tend to choose their lowest ISO).

Model Graphics, Photography and Self Imaging Technique
Model at its peak is called, a supermodel, a term originally pinned on Cindy Crawford, the original model of American fame last year. Then he is now mentioned every day, sekerap world petantang petenteng in our little world.

“Supermodel is a model of high-paid fashion and usually has the reputation of the world and often have a background in haute couture and commercial modeling. [1] This term is used in popular culture in the 1980s until the 1990s. Examples of supermodel Gisele Bündchen is from Brazil and Heidi Klum of Germany. (www.wikipedia.org) “

Derivative of the reference to the above include: amateur models, advertising models (a person who appears in your ad memampangkan TV, radio, magazines, etc.), magazine cover model (usually face reproduced on the covers of magazines). The reference is based on the job.

Once again,

“The model is a plan, representation, or description that describes an object, system, or concept. (Www.wikipedia.com).”
Then,

MEMPOSEKAN self-pingir on the edge of the road, the concrete wall of the building, attached to electrical poles, the corners of the intersection, the four-wheel vehicle body, the object is visible. This is what makes the public areas in this city as a poster display market, in the corner of the terminal there.

Want to oval-faced, thin, tapering?, Or black, brown, white?, Or rather on the skinny, fat, athletically?, Happy to pose smiling, thumbs up, jacket slung shoulder?, Or the graceful relaxed pose , with clothes slang?, berpeci and clad koko?, could be on the mustachioed face of a smile?, said it looked nice and make gemes.

Hubbub sketch face font and text with various characters meet ordinary eye, so it seems there is no place in this town without photos. There was a trend using a photo of himself lately. Photos of them declared passed verification by the Election Commission, of those who carry the agenda of KD-like verse song, “… Choose that I become candidates MU”.

Variety photo spread in the shape of candidates are varieties of graphic communication medium (posters, banners, Baligho, newspapers, Calendar, pins, shirts, even a radio spot). Also vary in size, there is a small, large, very large depending on the type of media used. Likewise with the amount depending dikantong pocket.

When the hubbub is a portion of a party, democratic party is now called, is less than 100 days ahead, to reach the eye sight was not free from these photographs. Unless you look to the sky, or into the ground. And this is the purpose of it all.

Not to me_narsis_kan themselves, or too selfconfidence, but as a strategy. Introduction self at the bottom level. Election 2009 is also due to set the most votes, via the introduction of aspects of yourself as pertontonkan profile necessity. This means that silence is risky at the time of minimal voters.

Now the 35 political parties (parties) will fight in Serumpun Sebalai. There are several large political parties with large figures, there is a new political party with the names of respectable, there is also a new party with new faces certainly. All have the same agenda, making sympathy. When the 45 competing Caleg 573 Parliament seats Bangka Belitung province, from this figure using the strategy posters show themselves, so you can imagine the chaos this party. if every candidate put 10 artifacts communication with a photograph of yourself, then there will be a 5730 baligho, banners or any of our daily column of the page will be filled them-they are. Not to mention those who fought in the level of district legislature and the City, the central parliament and regional representatives of the Council (DPD).

Effective?

For the printer, this special blessing. Orderan printed banners, baligho, or posters will be booming over the approaching election time later. Sekitarannya business was also lucky, sort of photographers, designers, welders, carpenters. they are sort of chain elements in the upstream production to downstream products campaign ads, until later this knacks gallantly mounted in public places. For media owners, obviously.

Are scattered trinkets is an effective communications medium?, Yet can be known, but there are no scientific studies, successfully or not a photo of himself in meng_gol_kan candidates qualified for the new board chair is known, when calculating the official election results Election Commission diliris few months later.

For now, hope minimaladalah face recognition, tebar tebar-old charm. Over time, the community expected to be familiar with these faces. Analogy, the more often he is seen more closely in the liver. Gratitude-gratitude later, at the time hari_H elections, faces familiar to dicoblos.

Was that simple?, Of course. Or is it part of the strategy?, Could be. Initial identification, and the strength of parties who will speak in making sympathy. Not be denied, the greatness of parties also influence the perception of select choose. Especially with the influence of political parties themselves.

Using communications media trinkets were viewed from the cost side, terlalui not very expensive. Compared with the campaign via television, advertising per column in the print media, or a visit to the electorate. Posters and the like more efficient. In addition, long-lasting element of graphic communication knacks so factor that encourages candidates to gang advertised.

Long note, as if the varieties of graphic communication nge-trend at the moment. Yet another option, too much to say. No terfikirkan, or may be “not very renyek e”, “no sphere nyusah e”. Finally trooped through knacks tebar begituan charm. Rather than work to identify yourself, graphics product installation strategy in public areas may be not effective for the success of the campaign. Even reversed. Backfire. For lack jituan Happenings advertised. Although she felt was a good feeling.

When they face and accessories memampangkan campaigns in public spaces, meriuhkan views of the city, seize the clustering, we face, the face Serumpun Sebalai, Indonesia in the end is a sign of diverse faces, a question mark.

Strategy Jitu or boomerang?

As a political act, a campaign aimed at the achievement of support. The form of slogans, speech, printed material, broadcast tape-shaped item pictures or sound, are varieties of this form of imaging directed at engineering, and developed it in the effort equation or the introduction of an idea, issue or ideology.

Including, in the varieties of graphic communication with the manifold above the present, reproduced, placed in public spaces. Is part of the campaign. He may be spreading the message of self, other than the communication of ideas or spirit that was brought to the electorate.

When Ferdinand de Saussure introduced the realm of semiotics in communication, a discipline which studies the language, the language membahasa and processes. That in any object used by someone to express something to someone else, always has a dual role as “indicating something” as well as the “signified”. So, when scattered varieties of such communications or artifacts were not as simple as inanimate objects stuck in the ground. Apparently there is a sign and signified in any earlier graphic media knacks. Variety of meaning becomes.

If you see a campaign ad of our city, is not so complicated because the elements used seemed simple. Even so, the simplest graphical artifacts were still playing in the management sign. Playing neat sign with herbs will produce the message (image) specific. In view of the semiotics of advertising, there are special dimensions on an ad. These dimensions are interrelated and support to obtain a certain image. Advertisements, usually containing elements of the sign of the object (object) is advertised, the context (context) of the environment, people or other beings that give meaning to objects, and text (the text) that reinforce the meaning (anchoring).

Photograph of yourself, and then reinforced with slogans, text-based, giving special meaning. Similarly, facial expressions, body movements, a large selection of letters, thick thin, and other supporters formed elemen2 union sign (signifier). Small big products also make an impact. Location and position and type of installation media itself is very decisive. Not a thing in passing, but he became a propagator which turned out to be a message meant to subjectivity of each community.

Written language that, according to Saussure was signed at one of those signs. And no more pictures or symbols is a way of language in it. Again, a poster with another poster that can be interpreted differently, an earlier graphical knacks can mean something for a group of people, while for other groups it could mean something else.

Posters or the Mampang baligho and junction on the outskirts of our city streets, generally showing a close-up, margins could be in addition to the left, right or center, with the placement of approximately 50 percent of the page. The remaining elements of the text and other marks.

When a poster displaying only a close-up images can be different meaning to the semi-full body. A close-up indicates “mediocre”, look like pieces of voters in later, complete with a list of the order. Signifier photos of semi-intact may reflect self-confidence. Similarly situated, if the centering and meet the lay out, this refers to the center of attention. Was that shares in proportion to other signs in the last perwajahan knacks, referring to the dividing opportunity to appear and sign visible.

At first glance, view photos berpeci average and clad Koko, safari suit or a uniform political parties. The berpeci and berkoko, would like to emphasize religiosity and closeness with the majority, was a suit refers to the formal and authoritative impression. Other parties with a suit, could refer to the greatness of his own party. There is also a shirtless young man typical slang now, which is signified_nya someone who “really slang”.

Likewise pose like a finger pointing, there was like about to shake hands, thumbs-up. This poses a living, as a dynamic reference, which also depends on close-ups. Also like the look, or a standard photo ID cards, so its reference well biasa2 aja. Including facial expressions, whether to laugh, smile, flat. Smiling reference to the warm-hearted and full of warmth, while flat refers to the seriousness and formality. A laugh, referring to the humorous figure. This last seems to not exist.

Strengthened by the number of candidates in the table, fontnya enlarged to the same size, so that voters see the obvious. There is accented with red and white flag images, flag of the party. Also juxtaposed with images chairman of the political parties or authorities in this country, because it happened at the party. Sometimes as large as the corresponding picture of candidates, can also be smaller. Photos coupled with a magnifying This refers to the support and political blessing.

Next brac media was added to the text, reads like a wedding invitation, “Please Doa Restu”, reference is to the candidates asking permission to be advanced to candidacy as well. Text as the anchoring point is again sounded casual. Impression troop used to make this text a common standard, nothing special.

Why do we choose you?, Should be delivered. The text in the form of slogans, like “Let’s Changed,” “Clean and Care”, or text such as, “I let your behalf”. These texts refer to the answer to this question. Persuasive and seductive tone better than “Please Doa Restu.”. As anchoring on one-way communication medium, the text should be really powerful.

If the sidewalk is attached to the media knacks lined neatly in a red light intersection, they huddled together, like seizure positions. This new beginnings will be busy later, after the addition of a political party flag, or major holidays. Boisterous posters, banners, baligho, flags of political parties on the side of the road segment, flagpoles and trees were included as before. In my village, the crowd is unparalleled as 1 Muharram celebrations. For Happenings placement, the candidates we are quite telling.

What’s important is how the packaging of this message to the community, managed at the level attitude (behavioral). End choose. When viewed, and accepted sight keep runtun process memory in the brain, and then perceived (encoding) in accordance with backgrounders can be ideology, norms, there will be a subjective meaning.

That is why then became a cultural context-bound reference for the success or failure of communication on an ad. For example, ad safari suit candidates who have the connotation of formality and the intellect is not necessarily in accordance with the cultural context of a particular community groups. Safari jackets can have different meanings, such as the existence or the sophisticated elites who always identical with the suit. Bookmarks (signifier) candidates could have a landmark suit (signified) “the elite”. Signs can not be released to the context, for example traffic signs (traffic lights) is useful at the time he posted on the highway. The sign would be useless if installed in the cane fields in the tribal hinterland.

Finally

Communication not only as a process, but the communication as the generation of meaning (the generation of meaning). When we communicate with others, at least these other people understand the intent of our message, kebih less accurately. So that communication can be done, then we must create a message in the form of signs (language, words). The messages that we make, encourages others to create meaning for himself related in some way with the meaning we make in our message. The more we share the same code, the more we use the same system of signs, the more closer “meaning” we the people are the messages that come in each of us with other people

When the current era of creativity in advertising is a demand, an advertising designer demanded how she had to get out of the situation called “me too” positioning (to it). Candidate advertising designer should try to escape from the position “than that to it” only. Referent / seidealnya reference free from the appearance of a mature, intelligent, nurturing, and the like, so that it moves signifier extended in the presence of nan wise men in the context of a board of distinguished figures. Resulted in creative campaign ads, too powerful attract the masses. But instead of creative, a reference mark for the referent-that’s hard to even find the varieties of graphic communications media today.

Compare, baligho our service provider, 3 (Three), which only displays a black baligho sahaja, then accented with a white question sentence?. This ad is intriguing and stimulates the brain. The sequence of signs runut conveyed, from the beginning and then presented with a question mark on the next day strengths, the new end, know what it 3 (three). Creative marketing concepts. Sekreatif, other operators, who use sign as a signifier of the monkey. This is different but, to borrow a phrase now, “kereeeen”.

Said Roland Barthes in “The Death of Author”, that when the sign (advertising) has been born and tertayangkan the “author is dead”. In the sense that no power of advertising (the man behind the ad). The power is in the public. Interpret their own free society intent of the ads that appear.

Once again, playing with varieties of graphical communication in one direction is like throwing bait into the river, when many would just get caught, but like a boomerang, throwing ketidakjituan might turn around and create a gap between candidates and voters .**

Introduction to Photography Tools and Techniques

Glance Photography

The word photography comes from the words photo meaning light and the graph which means the image. So photography can mean drawing / painting with light.

Camera Types

Film cameras, now also known as analog cameras by some people.
• Film Format
Before we stepped into the types of film cameras is useful to know in advance a variety of formats / film size.
1. APS, Advanced Photography System. Small format 16x24mm film size, packaged in a cartridge. Although this relatively new format, but not popular. Stores that sell this type of movie hard to find in Indonesia.

2. 135 format. Also known as 35mm film. Has the size 24x36mm, packaged in a cartridge containing 20 or 36 frames. This format is the most popular formats, many of us go on around us.

3. Medium format

4. Large format

• Type of Film
1. Film B / W, black and white negative film.

2. Color negative film. The most popular, we often use.

3. Positive film, also called a slide. More expensive and prone to overexposure. Nevertheless colors produced better because it can capture the contrast range more widely.

• The types of cameras Photo
1. Pocket / compact. Pocket camera. Popular for ordinary people, simple and easy to operate. Using 35mm film format.

2. Range finder. Range finder camera. Small, at first glance like a pocket camera. The difference is, this camera has a mechanism fokusing (hence called Rangefinder). Generally use 35mm film format.

3. SLR, Single Lens Reflex. Single lens reflex camera. Popular among professionals, amateurs and hobbyists. Generally have replaceable lenses. Using 35mm film format. Also called the camera system.

4. TLR, Twin Lens Reflex. Double lens reflex camera. Usually use medium format.

5. View finder. Usually use medium format.

The camera manual and automatic camera

SLR cameras are already equipped with the latest autofocus and autoexposure system but could be operated manually.

Digital Camera

Digital Camera Using a digital sensor instead of film by using storage media (Storage) Berua memory cards, sperti SD, MMS, and so on.
6. Consumer. Pocket camera, cheap, easy to use. The lens can not be replaced. Most have only fully-automatic mode. Just point and shoot. Some, like the Canon A series, has a manual mode.

7. Prosumer. SLR-like, high prices. The lens can not be replaced. Shooting Mode manually and auto.

8. DSLR. Digital SLR.

Camera Lenses

The eyes of the camera, in general determines the resulting image quality lens has 2 important properties of focal length and maximum aperture.

Field of View (FOV) of each lens has a wide FOV depends on the length and area fokalnya film / sensor is used.

Field of View Crop, often mistakenly referred to the focal length multiplier. Almost all digital cameras have sensors that measure smaller than 35mm film, then in the field of view digital cameras is smaller than the 35mm camera. For example 50 mm lens on the Nikon D70 has the same FOV with a 75mm lens on a 35mm film camera (FOV crop factor 1.5x)

Lens Types

a. Based on the prime-vario
• Fixed focal / Prime, has a fixed focal length, for example, has a Fujinon 35mm f/3.5 focal length 35 mm. Prime lens is less flexible, but the quality is higher than the zoom lens at the same price.

• Zoom / Vario, has a focal length that can be changed, for example Canon EF-S 18-55mm f/3.5-5.6 has a focal length that can be changed from 18 mm to 55 mm. Flexible because of length adjustable fokalnya.

b. based on the focal length
• Wide, wide FOV lens, focal length 35 mm or less. Usually used to photograph the landscape and buildings.

• Normal, focal length of about 50 mm. Lens is versatile, fast and cheap.

• Tele lens with a narrow FOV, focal length 70mm or more. To take pictures from a distance.

c. based on its maximum aperture.
• Fast, has a wide maximum aperture.

• Slow, has a narrow maximum aperture.

d. special lenses
• Macro lens, used to take pictures at close range

• Tilt and Shift lens, can dibengkokan.

Conditions lens wide / telephoto (based on the focal length) above apply to 35mm film camera. Nikkor 50 mm lens becomes a normal lens on a 35mm film camera, but a telephoto lens when used on Nikon D70 digital camera. FOV at Nikon D70 Nikkor 50 mm lens equivalent to 75 mm FOV on a 35mm film camera.

Another assist devices for the Camera (Photography):

Tripod
Required to shoot with a slow speed. At slow speeds, to avoid camera shake when held by hand (handheld). In general, the minimum speed handhel is 1/focal. Bringing a tripod when hunting can be troublesome. For the purposes of hunting is usually carried tripod is a lightweight tripod and small.

Monopods
Similar to the tripod, one leg. More easily transported. Can only eliminate vertical shake only.

Flash / flash / flash
To menerangai objects in dark conditions.

Filter
To filter the incoming light. There are many kinds.
• UV, UV light filter to prevent hazy on foto2 landscape, often used to protect the lens from dust.
• PL / CPL (polarizer / Circular Polarizar) to reduce shadows on the non-metallic surfaces. Could also increase the contrast for the sky.

Exposure
The amount of light entering the camera, depending on the aperture and speed.
• Aperture / diaphragm. The bigger the aperture the more light inside. Aperture is expressed by a number of other figures as follows: f / 1.4 f / 2 f / 3.5 f/5.6 f / 8. the greater the number (f number), the smaller the aperture aperturenya.

• Shutter speed / shutter speed. The sooner, the less light that entered.
• ISO, said sensitivity sensor / film. ISOnya higher then the amount of light needed less. ISO 100 film requires 2 times the amount of light ISO 200 film.

Example:

Combination diaphragm f/5.6 kec. 1 / 500 at ISO 100 equivalent of the diaphragm f / 8 kec 1 / 500 or f/5.6 kec. 1 / 1000 at ISO 200.

Exposure meters (light meter)
Almost every modern cameras have an internal light meter. It is also available external light meter.

Exposure metering (often abbreviated to the metering only), is a method of measuring light
1. Average metering, measuring the average light the entire frame.

2. Center-weighted average metering, measuring the average light in the center of gravity.

3. Matrix / Evaluative metering, Measuring the light in various parts of the frame, and then calculated by the methods of certain automatic.

4. Spot metering, measuring the light only on a small section in the middle of the frame only.

Exposure compensation, 18% gray.
Exposure meter is always measuring the light and produces bright images that measure the resulting range in 18% gray. So if we hit a piece of white cloth and use the exposure settings as shown by the meter, then the white cloth will be gray in color. To overcome this we have to do exposure compensation. Our exposure to be added so that the white cloth.

Under exposured, photos too dark because of lack of exposure.

Over exposured, images are too bright due to excess exposure

Term stop
Rose 1 stop, it means increased exposure to 2 times. 2-stop ride, which means increased exposure to 4 times. Down 1 stop exposure was reduced to 1 / 2 times. Down 2 stop exposure was reduced to 1 / 4 times.

The increase in the aperture 1 stop as follows: f/22; f/16; f/11; f / 8; f / 5.6; f / 4; f / 2.8; f / 2. Different f-stop number of each is 0.7 times (1 / Ö 2).

An increase of 1 stop kec. Rana as follows: 1 / 2000; 1 / 1000; 1 / 500; 1 / 250; 1 / 125; 1 / 60; 1 / 30; 1 / 15; 1 / 8; 1 / 4; 1 / 2; 1. Different speed of each stop is 2 times.

DOF, Depth of Field, Depth of Field.
DOF is the area around the focus sharp. The depth of field is influenced by a large aperture, focal length, and distance to the object.
o Aperture, the greater the aperture (smaller f number) will be more shallow DOF / narrow.
o focal length (real), the focal length, DOF more shallow / narrow.
o The distance to the object, the closer the distance to the object of the DOF more shallow / narrow.

DOF Selection
o If a narrow DOF, FG and BG will blur. Narrow DOF used if we want to isolate / emphasize the object from the surrounding environment such as the portrait photographs or pictures of flowers.

o If the DOF wide, FG and BG looks sharper. Wide DOF used if we want almost all parts of the image appears sharp, as in landscape photos or photo journalism.

Shooting modes

Auto mode, point and shoot mode, live capture and snap.
6. Full auto, the camera that determines all the parameters.
7. Portrait, the camera using the largest aperture to narrow DOF.
8. Landscape, the camera uses the smallest aperture.
9. Nightscene, using a slow speed and flash to capture the object and the BG as well.
10. Shuter fast speed
11. Slow shutter speed

Creative zone
12. P, AE program. Similar to the auto mode with more control. In this fashion we can control the exposure compensation, ISO, metering mode, Auto / manual focus, white balance, flash on / off, and continues shooting.
13. Tv, shutter speed priority AE. We determine speed, the camera will calculate the appropriate aperture.
14. Av, Aperture priority AE. We determine the aperture, the camera set the speed.
15. M, manual exposure. We are determining the aperture and speed manually.

Composition and Angle.

Composition is the placement of objects in the image frame Angle is the angle photography, from the bottom, top, or parallel. The composition and angle is more related to the art of photography. Factors tastes great photographers influence.

Camera Care Tips

February 2, 2010

Digital cameras have advanced, but could not take good care of? Well, it was the same as spending money for the cost of repair or buy new!

Digital cameras may be a mandatory thing for the holidays with family or when a reunion with old friends. Caring for these high-tech items must not be arbitrary. There are several things you need to know to care for her.
• If the camera is accidentally plunged into the sea water, first rinse with fresh water, then immediately dried. Sea water can quickly make the body and the inside of the camera rusty.
• To clean the lens, use a special blower camera you can buy at a camera store.
• After that, the new lens cloth with soft cloth (like a cloth to wipe his glasses), or a special lens tissue. Do not wipe the camera lens with normal tissue, because the coating on the lens can be detached and tissue filings will stick. This will make even more dirty lens.
• To clean the camera body, use a soft brush.
• Do not store the camera in a wardrobe, bookshelf, or other places which moist. Keep the camera in a dry and cool. If possible buy a special box or cupboard for storing cameras, or store it in glass / wood, or a clean glass jar, and put some silica gel.
• If you are finished using the camera and want to keep it, copotlah battery from the camera body to prevent leaking batteries and store separately from the camera.
• The battery will be easily damaged if used in cold areas. If you are in a cold place, do not leave the battery in the camera. If you’re not in use, store the battery in your pocket.
• Keep the camera from direct sunlight, because it can damage the plastic and rubber.
• Keep the camera out of mothballs or air freshener, because it can damage the camera chip and cause spots on the lens.

Maintenance is good and right will make your favorite camera certainly durable and produces images with good quality!

Indoor – Outdoor Bounce Flash and / diffuse
Camera-Digital.com (Agus Chiawono)
The use of Flash is very helpful when we photographer at room dark light conditions. But if we do not exactly set the settings to use flash, then the image will not be maximum, sometimes less bright or even too bright. For the continuation of this article will explain how to use flash indoor and outdoor as well as how flash is used and an explanation of the bounce and diffuse the flash. (This article is the connection from the article Blitz for Dummies)
Indoor Flash
Blitz often even almost always used in the room. The reason is because in the room lighting is usually somewhat less bright light to produce images that can be seen. Indeed, there is a technique using a slow shutter speed to capture more light, but this usually causes a rather blurry picture because the cameraman’s hand shake and the movement of people who want us to photograph. Therefore, we usually use a flash.
Its use is usually simple. We can set a digital camera on auto and let it do its work or it could be our own setting using the calculations done above. Not difficult. Only, there are some things we need to consider in order to get maximum results.
1. Do not take pictures of objects that are too close to the flash straight faced. Take for example the flash GN 20 which I think is adequate as an external flash for digital cameras in an indoor shooting in a room (not the hall). If we want to mention the shooting at a distance of 2 meters with ISO / ASA 200 then we need f/16 is not available in most of the PDC and will produce images over. Therefore, for the PDC / DSC are usually already have a built-in flash to TTL and has the GN rather small (8-12 on the part of the PDC, the Nikon 12-14). Use it instead of an external flash to objects rather close.
2. Combine flash with slow shutter speed to get the main object tercahayai well and has a background light sources are also well captured. This is a technique that’s worth a try, and often produces a beautiful picture. Do not be afraid to use a low speed because the object that was subjected to flash will be recorded freeze (freeze).
3. When the room was quite dark, beware of the red-eye effect / red eye effect. This red-eye effect occurs because the pupils are dilated to familiarize yourself with the light but rather darkness suddenly startled a very bright light from the flash. If the camera and / or flash is pre-flash/red eye reduction facility, use it. If not, change the angle akali with a flash of light coming directly not to the eye.
4. In the room there was a strong light source like a spotlight. Avoid taking pictures with facing directly into the strong light source but want to get a silhouette that is not perfect (compensation under 1 to 2 stops for a good silhouette). In this case, use flash to fill in / illuminated object that you want photographed.

Bounce / diffuse
Flash is a source of very strong light. In addition, the flash is the light that comes from a small light source (narrow). Therefore, if the light is exposed directly to an object will cause harsh lighting (harsh). In most of the documentation photographs of personal consumption where officers documentation using point & shoot camera (film / digital) can be accepted. But in a higher level where the results of these photographs will become public consumption, hard path of light will give effect less unsightly. Plus this will usually cause a flash of light bleaching thing was a little white and cause certain details disappear.
There are several ways that we can do to avoid this in terms of softening the light:
1. Expanding the field came to light that is reflected into other areas (bounce).
2. Spreading the light coming from a small source is so widespread (diffuse).
Bounce flash is done by reflecting the flash into a broad field so that the light comes in a wider angle. We can use the ceiling or wall in the room. If the external flash mounted on a digital camera connected via hot shoe, then the flash should have a tilt facility to reflect light. If the synchro is connected via cable, then we can put flash on a bracket with a position facing upwards / sideways or hold such positions. Reflect the correct position so the light falls exactly on the object is to confront these flash on the ceiling in the middle of the photographer / flash and the object. Some things we need to consider the use of bounce flash is:
1. The distance to calculate the f / stop change is not a distance camera and the object, but turned into the distance traveled by the light flash. Normally at 45 ° tilt angle we will widen the aperture 1 stop and the tilt angle of 90 ° we widen the aperture by 2 stops. Surely this is only a brief guide. Depending on the technical implementation in the field.
2. Related to no. 1 above, the langit-langit/dinding distance should not be too far or it will be useless.
3. Always use a white reflective areas and dark. Color other than white will cause the color contaminated image and the dark color will absorb the light flash.
4. Note the appearance of the image can occur on the other side of light. For example, if we reflect on the ceiling we will get a shadow under the nose or chin and if we reflect at the wall on the left then there will be shadows on the right. To overcome this we can put a bounce card on the front of the flash so that when we reflect the light up / side we still have a light that is not too strong which leads to the front and neutralize shadow appears.
To take a photo in the vertical, would be easier if we use a cable connection because we can easily expose flash upward when using brackets or held. But if our connection is hot shoe flash then make sure we have a swivel head so the facility can we play is facing up. Even better if we have a flash that can be tilt and swivel. This will accommodate most of our needs.
Another way to soften the light is to expand dispersinya. How to use flash diffuser. Flash diffuser will spread the light out of the flash in all directions so that light does not come out hard. Special diffuser generally available for a particular flash head flash considering different. We can also make your own flash diffuser for us to use the various tools. When we use a diffuser, we actually block certain areas of the light flash and turn it into another place. This reduces the power of flash that we use it. If we use a diffuser which is the result of buying, then we can read how much compensation we need aperture when calculating exposure. Usually found on the box or paper manual. If we decide to make your own, then we can perform the experiment many times to get the right numbers required to compensate other times.

Outdoor Flash
Brief if we think about using flash, then we’ll know if it applies to an atmosphere of lack of light shooting. Therefore, we are not thinking about the need for flash in outdoor photography (during the day, of course) because the sun was very bright. This is where our mistake begins. Flash is required to shoot outdoors, especially on:
1. Condition object back to the sun. In these conditions, the camera meter will think the atmosphere was light enough so it will cause the object to be photographed the dark / under strong light such as a waste because it is not reflected by the object. How to outsmart is to fill in on an object so that even though the setting is very bright but still get the light objects.
2. The sun is above the heavens. This will cause the image appears on the bottom of the nose and chin. Use a flash to eliminate them. To soften the light using bounce card or diffuser.
3. Objects are in the open shade (shadow). Flash is used to obtain the same lighting on the overall image of the object because it will make the dark shades of different parts of objects much less a human face.
4. The sky was blue and seductive. If we are not tempted by the blue sky and willing to get pictures of white sky when shooting outdoors so please do the metering on the object without using a flash or with flash. If we are willing to object as long as the lack of light blue sky please do the metering on the sky. Well, if we want to keep the blue sky and object tercahayai well, use the metering on the sky and fill flash on the object. This will produce the right mix and right.
5. The sky was overcast. When the sky was overcast, do not hesitate to use the flash because the effect would be the same cloud as if we were under the shadow.

Blitz for Dummies
Camera-Digital.com (Agus Chiawono)
Blitz or flash freely translated into the flash. This is one accessory that is widely used in the world of photography. Its main function is to illuminate (mencahayai / illuminated) objects to the lack of light exposure well. But later began expanding its use to produce artistic photographs. However, flash photography is one thing to be learned. Most of the readers must have often used the flash well and getting good results also, but this paper will discuss the basic knowledge required to use the flash correctly. Correct in the sense in theory can be accepted and justified in terms of using a base that can be explained scientifically.
Using the flash is not merely a flash lit it, directing the camera and click and be a single photo and beautiful light, but there are things we need to know for the sake of getting good photographs and correct it. Whether we look at digital cameras as art or technology, the flash still is a means of simplify, optimize, and enhance creativity.

Meters, Aperture, and Shutter Speed
Photography briefly defined as the science is often painted with light. In conventional photography using film, we ‘paint’ with light in the film layer. Term is to burn the movie permanently using light with a certain intensity. The intensity of light entering the film or CCD / CMOS digital camera should be right. Excess lighting will cause the results of washed-out photos (commonly called over-exposure/OE) and lighting will cause the results of the dark images (commonly called under-exposure/UE). So how to get the right light?
We know what is called lightmeter in the world of photography. Lightmeter some built-in in the camera body and some are handheld. We usually use is the built-in lightmeter it. We use to measure lightmeter reflective light that comes into our lens (if TTL) and the processor will determine whether the camera is in accordance with the type of film cameras installed in us. In the auto mode or programmed auto, the camera will automatically find the right combination of f / stop and shutter speed (explanation follows). In the aperture priority mode (A / Av) the camera will use the f / stop which we select and determine the appropriate shutter speed. In contrast, the shutter speed priority mode (S / Tv) the camera will use a shutter speed that we choose and determine the appropriate aperture. In manual mode (M) we will have to determine the right combination is guided by the camera meter.
Aperture or shutter opening is wide hole opened by the camera to allow light inside. Usually symbolized by the number f / stop. This figure is actually the result of a multiple of sqrt (2). Commonly used is usually started from 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, ff. To keep in mind, the greater the number the smaller the opening. Because it is usually written as the denominator fractions such as f/1.4, f / 2, f/2.8, f / 4, f/5.6, f / 8, f/11, f/16, f/22, and so on. Aperture is also associated with DoF (Depth of Field) or the space that we can sharply defined as a room in front and back of objects that are included in the range of focus. DoF is itself influenced by 3 things are:
1. f / stop where f / greater DoF would provide a wider (more and more regional focus).
2. Distance of objects where objects are further focus will cause the DoF is also widening.
3. The use of telephoto lenses where the lens will give a narrower DoF than a wide angle lens (wide angle).
Shutter speed or aperture is the length of the shutter curtain is opened to allow light inside. This figure is symbolized by a second unit and the increase / decrease in the form of multiples of ½. Example: 30s, 15s, 8s, 4s, 2s, 1s, 1/2s, 1/4s, 1/8s, 1/15s, 1/30s, 1/60s, 1/125s, 1/250s, 1/500s, 1/1000s, 1/2000s, 1/4000s, and so on. The slower the light coming in more and more.
As measured by the camera’s meter the incoming light intensity is. If the meter shows the lack of light then we can reduce the f / stop or slow the shutter speed. Conversely if the meter shows the advantages of light then we can expand f / stop or speed up the shutter speed. One thing to remember is that the slower shutter speed the more likely the object blurred by hand movement, camera shake or movement of the object itself.

Blitz and GN
To divide / classify blitz, there are several classifications that can be used. The first, based on the availability of the camera flash is divided into the built-in flash and external. Built-in flash from the camera itself while the external flash is a flash attached additional cables or hot shoe to the camera. In addition, we also can divide by the type / brand of camera. We know the dedicated flash and non-dedicated flash. Dedicated flash flash is made specifically to use certain features within a specific camera. Usually the camera manufacturer-specific flash out also for the camera range and can use features such as TTL, slow sync or rear sync, etc.. While non-dedicated flash has the general functions of most of the camera alone and can be used regardless of the type / brand of camera. Flash this type usually require a lot of computation because the flash is already dedicated’ve got the information from the camera lighting so that does not require additional settings again. There are also flash output power (GN) can be arranged and some are not able to (fixed GN). We’ll tend to talk more about the flash non-dedicated, non-TTL, and fixed GN.
In using flash photography, we will not escape from the calculations related to the intensity of light reflected back from objects that we cahayai. Therefore, we will see what is often called the GN (Guide Number) or flash power. In short we can say if flashnya powerful, it will be one object with mencahayai lighter and can reach more distant objects.
GN is basically a simple calculation of flash power. There are 2 kinds of writing GN using a different calculation of unit m (meters) and feet (feet). Normally in Indonesia, we use the count to m. This is one of the considerations are also due to flash with the same strength, the number GN m and different feet away. In addition, GN is generally written for the use of film with ISO / ASA 100 and wide angle (35mm/24mm/20mm).
GN is a product of the distance from the opening (f / stop or aperture) in certain conditions (ISO / ASA 100/35mm/m or ISO / ASA 100/35mm/feet). For example, if we want to use flash to photograph a person standing at a distance of 5m from us using a 35mm lens and we want to use f/2.8 then we need to flash GN 14. Calculation commonly used is usually just find the right aperture for a particular blitz. For example, the GN 28 will flash to photograph the object is 5m that we will use f/5.6.
GN is only a guide for photographers. Not set in stone. Which affected a few. One of them is the ISO / ASA is used. Each 1-stop increase in ISO / ASA will cause GN increased by sqrt (2) or approximately 1.4 times (or the farthest distance multiplied by 1.4) and 2-stop improvement in ISO / ASA will cause GN increased 2 times (or the farthest distance multiplied by 2 ).

Film SLRs vs. Vs. Prosumer Digital Camera. DSLRs
One thing to remember is that the film cameras and digital camera is different. In the digital camera itself, there is a difference between pocket camera (in this case is usually able to use additional flash is the PDC / Prosumer Digital Camera)) and Digital SLR (DSLR). The first difference, of course, in terms of the proportions of the sensor / film to the lens. Because the digital camera sensor smaller than 35mm film, then we’ll be stuck on a long comparison of different lenses. To obtain a similar angle as 35mm, so the camera with a sensor 1/1.8 “will use the lens of about 7.5mm, D100 will use a 24mm lens and 10D will use a 20mm lens. This is the effective length of the lens to start the calculation using the flash GN.
Second, zooming. At the PDC, zooming will cause a change f / stop is slower (large numbers) and so also with the use of consumer zoom in SLR / DSLR. For example, we know f/3.3-f.5 lens 35-70. That is, the largest opening is f/3.3 at 35mm and the largest opening is f/4.5 at 70mm. This certainly will affect the object being photographed.
Use the zoom on the camera is usually coupled with the use of the flash zoom head. Telephoto lens / zoom to narrow the angle and zoom lens coverage on the flash head to narrow the dispersion of light that flash in other words increasing intensity, so they can reach further. Zoom head position and the telephoto lens on the wide positions would cause a part of the photo is not a light or familiar with the term vignet. Zoom head in wide positions and telephoto lens in position will cause a flash of light can not reach the remote object (after all, it’s worth a telephoto lens? For photographing objects that far?). In addition it also happens if we attach a 35mm lens on DSLR and then we do a flash calculation using the calculation remains to SLR is usually because the angle is equivalent to 50mm or more (depending on factors pengalinya). Actually there are no significant problems that arise, but we are ‘wasting’ the light in vain.

Tips for Making Green Photography


Why do professional photographers using DSLR full-frame

February 1, 2010

First, allow me to preach the presence of the first Full frame DSLR from Sony is called the Alpha A900. Attend a DSLR camera with the highest current resolution of 24 MP (or 6000 x 4000 pixels, wow!), Sony was not playing in a professional working in the world. Carrying 30 million pricing, advanced camera from Sony is (though without the live-view feature and the internal flash) is ready to compete with the Full Frame DSLR such as Canon’s established EOS 5D mark II and Nikon D700.

Nikon D90, my favorite DSLR camera

Hey, today’s my birthday date. In addition to a special gift from his beloved wife, akupun a ‘gift’ that was quite special is the launch news Nikon D90 DSLR camera that was so awaited by millions of photographers around the world.
Yes, like them, I also make this the Nikon D90 as my favorite. Not only the big names that made my Nikon camera to admire 13 million dollars worth of this, but also legends D70/D80 series known as the middle-class DSLR camera’s best selling and quality, which makes me so enthusiastic about the presence of this single item.

Optimize the camera’s manual features you

It could be the first since someone bought a digital camera, the mode is always used to photograph the AUTO mode. The first reason for this mode is the mode most easy to use and relatively reliable in a variety of situations without fear of the results will be disappointing picture. The second reason may be due to chance in the digital camera is available only AUTO mode only, so ‘forced’ can not create more distance with manual mode. It is generally a digital camera type of point-and-shoot designed very simple and not equipped with many features like cameras Prosumer manual. But for those of you who have a camera with manual features, you still wear masihkah AUTO mode all the time?

Focus, Mega Bazaar & Jave 2008

Focus 2008 became an annual event for terakbar exhibition of photography in the country, held at Jakarta Convention Center, Senayan. The exhibition The exhibition coincided with the 13th Mega Bazaar Computer and Jakarta Audio Video Exhibition (JAVE) 2008. This grand event should be an appropriate arena for displaying camera maker before a new product can only be viewed via the internet. Also here are also held seminars and workshops which would be useful for photography enthusiasts.
In Focus 2008 to be held tomorrow, I hope to see and try to direct the latest DSLR camera that will be the favorite in many circles this year, like the Nikon D300 and Canon EOS-450D. Referring to the exhibition of the past, usually Sony made a booth by giving us the flexibility to try to direct product. Hopefully, tomorrow Sony’s Alpha DSLR display A-300 so I could feel the Quick mode claimed viewnya Live best and fastest Live View DSLR than others. I also look forward to falling prices Nikon lenses in the exhibition this time, who knows something suitable in the bag. My prediction, the lens that will drop the price of the AF-S 18-200VR, 55-200VR, 70-300VR and 12-24. I also look forward to Sigma HSM lens range on display at the exhibition later, especially the Sigma 18-50 f/2.8 HSM. Sorry for my D40 lens kit accompanied only just for this ..
For those who are looking for a pocket camera, the event is suitable for comparing various options. After reading the digital world of blogs, you may finally have some alternative options, it’s time to see and besoklah held directly. If the camera can try, consider the quality and ergonominya body, try to use pictures and feel the shutter lagnya, ISOnya ability (light in the room quite dim JCC exhibition and suits to try high ISO), feel zoomnya, compare the various brands such as Canon, Panasonic, Fuji or Nikon. No matter if you are in the exhibition will not buy, yet more appropriate exhibition to know more closely. Can buy things later ..
Because the exhibition coincides with the Computer and Audio Video, it’s worth the big expo is also not passed away. Typically in a computer exhibition, a major sale was held. Than just memory cards up to Intel Core 2 Duo processors will be on sale here. New motherboards with new chipsets will be on display everywhere, not to mention various berchipset Nvidia graphics card or ATI with SLI technology, or Physics. For those looking for a laptop, would be confused with the selection of laptops from various brands. Hopefully Asus gives big discounts for Asus Eee PCnya. For audio video, let alone the expected flood later if not cheaper LCD TVs. By starting the achievement of margin keuntungandari LCD TV, there is no reason for producers keep prices so high LCDnya TV. Imagine the wide-screen LCD TV with affordable prices, who can stand the temptation?

Canon A650IS, hands-on preview
Posted by Erwin M. | Posted in Photography | Posted on 21-02-2008

This morning I was surprised by my work friends who had just bought a Canon A650IS and he was pleased to lend me his camera. Without a longer length, I can easily picture this camera with my HP camera (sorry picture noise worse). The first impression, like the Canon A series 6xx with 4 batteries (A610, 620, 630, 640 and 650IS), is a solid ergonominya. This is due to the increased grip due to the number of batteries up to 4 pieces, so it was like holding a mini Prosumer. To determine the performance of this camera does not take long for general I felt was as good as my friend’s A610 purchased in 2006. I found Auto ISO feature smart enough not to use high ISO even in dim lighting. For example, in my office that uses fluorescent light, to keep this 650IS normal exposure ‘only’ increase the ISO to 500 and this is better than other cameras tend to ISO 800. Oh yes, for the Auto ISO did not have a guessing, because the ISO value is written on the top left corner of the screen when the shutter button is pressed half, nice.
Regarding the lens and stabilizer, well, relatively well. Distortion at the wide, indeed, quite clear (and reasonable for the 6x zoom lens like this) but the contrast and sharpness of this lens at all focal length (35-210mm) deserves thumbs up. Zoom lens feels smooth and responsive (although not too quickly). Stabilizer also works well although I can not give a comparison here because the picture has not been moved to the PC.
I have tried to fashion is P (program), Tv (shutter priority), Av (aperture priority) and M (manual). I am quite impressed with the capabilities of this lens when used A650IS Av mode because it can give a pretty good Bokeh at f/2.8 and the diaphragm lowered down to f / 8 the results of a sharp image in both the object and background. M mode when you try a little confused when I switch set the shutter and aperture value, this is because of the absence of semajam jog whell or joystick. Unfortunately .. But after finding the way, was so long accustomed. The way is by pressing the Exposure Compensation button, then the time has determined the value of the shutter, we can move on to the aperture value.
Because of the limited time of borrowing, I did not have time to try other features such as manual focus and more. But I sure do the same with the A610 I’ve ever tried before. Essentially manual focus remains on a pocket camera is not as easy with DSLR camera. This is because the shift is done electronically. However, this feature would be useful when auto focus failed to lock the object (like a cat in a cage for example).
In short, the good:
• 6x zoom lens, sharp and effective focal range
• stabilizer with lens-shift system
• LCD screen can be rotated
• Auto ISO smart
• using 4 AA batteries (instead of 2 batteries)
• new features such as face detection
• there is an optical viewfinder
The bad (not too bad):
• little distortion at wide-end (though still reasonable)
• would be better if started at 28mm wide (rather than 35mm)
• histogram does not appear moments before shooting
• without jog-whell/joystick
• be more fun if there are RAW file format
• 12 MP resolution too forced for such a small sensor (perhaps 10 MP more rational)
Overall, I was impressed and acknowledged the greatness of the highest series Canon PowerShot A series of this. Highly recommended IMO ..
Prosumer camera trends of today

As we’ve known, the more expensive DSLR. Price Nikon D40 or Canon 350D is now cheaper than Nikon Prosumer lawas like Olympus 8800 or 8080. Clearly to win the Nikon image, not to mention the features and speed. Prosumer price range to be ‘completely wrong’ because people are lazy little expensive to buy, but people are too cheap, too scared to buy. To remain exist, Prosumer eventually evolved into a super-zoom cameras are no longer promote the image quality but more to the all-in-one solution. Evidenced by the emergence of over 10x zoom camera which photographs the results are generally mediocre. But past who can imagine 2 million worth of cameras have lenses with a range of up to 18x?


Some Techniques in Photography

January 30, 2010

Technical Photography & Functions

Photography is not all about the camera. It is said that photography is the art of playing with light. In the absence of light, then it is impossible photography. Produces a good picture, must have a strong vision in terms of ‘seeing’. Noticing the light, composition and moment are the things that is important to note in making images that can be categorized as ‘good’.

However, it seems impossible to produce a picture like that if it does not know and understand the technical each basic photography. Photography is not all about the camera, but the camera is a tool to deliver our vision. So, if it needs to know and understand how the camera works.

The main task of the camera is set intensity of light coming in and in the end of the film / sensor (hereafter I call the medium). If the camera allows too much light coming in the medium will be burned (overexposed.) And vice versa. How do I get the light coming in was not excessive and no less, or in other words ‘pass’. Here I describe one-one.

Aperture

Or is often called a diaphragm or lens opening is a function to regulate how much the lens opens. This function is more precisely located on the lens. Logically, the bigger the opening, so the more light will enter. Like a water faucet. The bigger we open the faucet so the more water will come out.

Writing the correct Aperture is f / x. Therefore, when told his Aperture value is 5.6, then the correct writing is f/5.6. So do not be upset if someone said that the 2.8 lens opening larger than the lens opening 5.6. Because if you are writing is true mathematical khan? (f/2.8> f/5.6), but most of us are reluctant to say f/2.8 or f/5.6, because we are simple people’s … Very Happy

Side Effect of Aperture

Like cough medicine that has side effects, as well as the aperture. The side effects are greater the lens opening, the smaller it will be the focus area. And vice versa. This focus area commonly known as the DOF (Depth of Field). For more details, see the following picture:

________________________________________

f/3.5, 1 / 125 sec @ 50mm ISO 100
________________________________________

As an example picture above, shows that the focus only on the stigma of the flowers alone. While the crown is out of focus (blur). But, taking a look at this little opening.

________________________________________

f/11, 1 / 200 sec @ 17mm ISO 200
________________________________________

In the example above is almost the whole picture look sharp (except for objects that are far away).

Shutter Speed

Or commonly referred to as shutter speed or speed duty to set how long the mirror open and closed again to limit how much light will enter. Like the theory of the tap, when we opened the tap too long, then the container will the water reservoir so that the excess will meleber out. If in the case of photography, the medium will be burned.

Writing the correct shutter speed is 1 / x. So when it is said that a photograph menggunkanan speed 60, then the correct writing is 1 / 60 second. So do not be confused to say that the 60 speed faster than 30. because the writing is so mathematically khan?

Side Effect of Shutter Speed

Like dating has side effects, such as hard glanced woman / other man, as well as the shutter speed. The faster the shutter speed, then the image will be more visible still (freeze). And conversely, if the speed is too slow image will look blurry because of movement is too fast, so that the object seen moving very fast. More details, please see the following photos as illustrations:

________________________________________

1 / 320 second, f/5.6 @ 17mm ISO 100
________________________________________

Horses are running (probably not dance khan?) Seems still to use a fast shutter speed.

________________________________________

1 / 15 second, f/11 @ 17mm ISO 400
________________________________________

people who are sitting looking sharp, while behind a moving vehicle looks blur.

ISO or ASA

Sensitivity level is medium in the light. The higher the value, the more levels of sensitivity. That is, if we change the value of the ISO or ASA becomes higher, while the aperture and speednya not changed, then the media will receive more light. And vice versa.

SIDE EFFECTS ISO or ASA

ISO is the sensor sensitivity level (medium), while the ASA is the sensitivity level of the film (medium), so the difference is only just dimediumnya. But the same logic. Except for side effects. Which if using high ASA film, the picture will look grainy (the shape of a small point but a lot). While the use of high ISO will generate noise (such as a worm, but many forms). Slightly amused wrote’ve let alone a lot =)

What is important is that we recognize the camera and its functions as a means of distributing our vision in producing an image. Thus, all functions have side effects, but this does not mean bad. However, we must be able to use it wisely. The question is, what effect is produced in order to reinforce the message? If you want even stronger sampeiin wrote himself …: p
