Digital Photography: all its many secrets
Having a digital camera, whether you have a plan to make a career out of photography or you are simply a hobbyist, is obviously important. But before buying a digital camera, there will be a lot of things to take note of. Camera accessories are one but an important feature is photo software. Many are available in the market while you can also download some in the internet. Also, digital cameras cost more out of the box than regular cameras, but offer the convenience of immediate viewing, multiple image storage, computer connectivity - and there's no film to develop. Compare additional features you might want: interchangeable lenses, steady-shot, burst mode, auto exposure, automatic white balance, voice memo, variable shutter speeds, manual focus and self-timer. In the past, photography was a costly and time-taking business. This meant photographs were taken cautiously so as not to waste film. Only the richest companies could afford to take hundreds of pictures knowing that only one would be chosen out of the bunch. Nowadays, because of technological advancements, amateur photographers do not need to worry about finances or the amount of time it will take them to produce one photograph. Experimentation is possible for anyone, and more relaxing and enjoyable. When it used to take hours to process a picture, it can now take under that to process several, and amateurs can benefit greatly.
White balance (WB) is the process of removing unrealistic color casts, so that objects which appear white in person are rendered white in your photo. Proper camera white balance has to take into account the "color temperature" of a light source, which refers to the relative warmth or coolness of white light. Our eyes are very good at judging what is white under different light sources, however digital cameras often have great difficulty with auto white balance (AWB). An incorrect WB can create unsightly blue, orange, or even green color casts, which are unrealistic and particularly damaging to portraits. Performing WB in traditional film photography requires attaching a different cast-removing filter for each lighting condition, whereas with digital this is no longer required. Understanding digital white balance can help you avoid color casts created by your camera's AWB, thereby improving your photos under a wider range of lighting conditions. A digital camera's auto white balance is often more effective when the photo contains at least one white or bright colorless element. Of course, do not try to change your composition to include a colorless object, but just be aware that its absence may cause problems with the auto white balance.
Quality sports shots are somewhat difficult to come by. Most people have limited access to events to photograph them. The further away you are from the event, the harder it becomes to capture the event in a pleasing manner. You may need a flash with a high output for photographing indoor events.The new modern flash systems produce great results. Some sporting events like gymnastics and others are no-flash events. It is best to talk to an event official before using your flash.
In computing, JPEG is a commonly used method of compression for photographic images. The name JPEG stands for Joint Photographic Experts Group, the name of the committee that created the standard. JPEG itself specifies how an image is compressed into a stream of bytes and decompressed back into an image and the file format used to contain that stream. The compression method is usually lossy compression, meaning that some visual quality is lost in the process, although there are variations on the standard baseline JPEG which are lossless. There is also an interlaced "progressive" format, in which data is compressed in multiple passes of progressively higher detail. This is ideal for large images that will be displayed whilst downloading over a slow connection, allowing a reasonable preview before all the data has been retrieved. However, progressive JPEGs are not as widely supported.
If you use a flash in a dark environment, you often get a red eye effect. This is because the light of the flash is reflecting from the retina, which is covered with tiny blood vessels. The more open the pupils are, the more red eye effect you get in your photos. Red eye is more pronounced in people with light eye color. It is also more pronounced in people with blond or light-red hair and in children. Many cameras have a built-in red-eye reduction pre-flash that helps reduce the incidence of red eye. Red-eye reduction works by having the flash shine a light into the eyes of the subject prior to taking the picture. This causes the pupil to contract. However, you have to make sure the subject is looking at the camera. If not, this technique won't work. Also be wary of using red-eye reduction feature when not necessary, because it may cause your subject to blink.
How do you begin to take good photos? The first thing to remember is this: It's the photographer that takes great photos, not the camera. Think about that for a minute. It's true isn't it? I've seen some people take great photos with a simple point-and-shoot camera, while some take lousy shots with the most expensive SLR. Always look for beautiful natural light. The best natural light usually occurs right before, after, and during sunrise and sunset. Be deliberate and creative. Think about what would make a good background, what would make for good colors. When you set out on a picture-taking spree, shoot 10 to 25 pictures so that you can be sure of getting a good shot. Vary the distance, setting, poses, or even the times of day.
