Curious about digital photography?
It is important to realize that there is no such thing as a perfect camera, one that will be the best for everyone. Although we sometimes talk about ‘cameras of the year’ or ‘top picks’, such lists and awards are really of little consequence. The camera that wins most accolades may not be the one that is most suitable for you. The important thing you need to do is to think about what you want from a camera; you need to know what the various specifications mean, and to work out which is the best for you. Even those aspects that can easily be quantified - such as the number of pixels the sensor records - are not always straightforward. For some people a 2 megapixel (Mp) camera may be a better choice than a 4 Mp model. Even where image quality is important, you cannot assume that a 5 Mp camera will necessarily give better results than a 3 Mp model. As in life, other things are seldom equal.
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.
It is usually taken for granted that white is white, with no variations. However, all artists would agree that this is wrong, including photographers. The white balance of a camera can make or break a picture, meaning you must learn to control it. In order to regulate it, you must set your camera to manual or custom white balance, and take a picture of something white. It must fill the screen, and should not be in shadows. If the result is not to your preference, you can always use your photo program to tweak the picture.
You may have already noticed that when you’re outside on a sunny day using the Sports/Action mode to take pictures of your child playing soccer or your pet catching a Frisbee, that you get these great action images that are worthy of submission to Sports Illustrated Magazine. But when you go inside and take photos of a basketball game with the same camera in the same “sports mode”, you get images that are only worthy of being erased before anyone else sees them. The main ingredient that’s missing in the indoor photos is “light”. The light inside a gym during a basketball game is minimal just as it is during a football game or soccer game after the sun goes down. Most of your sports/action photographs will be taken in available light. Flash isn’t always allowed and there’s also an effective range of your built-in flash (10 to 15 feet) that isn’t conducive to taking action shots from the stands. Taking a photograph of a moving subject without a flash under low light conditions can result in blurry pictures. The problem lies in the way that exposure works; the lower the light, the slower the shutter speed that the camera needs to make a correct exposure. The slower the shudder speed, the more chance that the picture will be “blurry” because of camera movement or subject movement.
JPEG is a format that makes changes to your photograph, such as adding lighting specifications or white balance. This is usually the best thing to save your picture as, because the results are generally satisfactory and the computer is smart about interpreting the data. However, sometimes you may want to take the raw photograph, which is the picture that has nothing added to it such as light specifications, and edit it yourself. You should do this if you are unsatisfied with the picture taken by the camera, as it is easier than trying to edit a JPEG image. In general, JPEG images are not as detailed as raw images which makes editing them difficult.
We’ve all see photographs where the people in the picture have spooky red eyes. These are photos taken at night with a flash. Where do the red eyes come from? The red color comes from light that reflects off of the retinas in our eyes. If you shine a flashlight in a person’s eyes at night, you don’t see any sort of reflection. The flash on a camera is bright enough, however, to cause a reflection off of the retina — what you see is the red color from the blood vessels nourishing the eye. Many cameras have a “red eye reduction” feature. In these cameras, the flash goes off twice — once right before the picture is taken, and then again to actually take the picture. The first flash causes people’s pupils to contract, reducing “red eye” significantly. Another trick is to turn on all the lights in the room, which also contracts the pupil.
“Picture-perfect” is a term almost always associated with photography, which makes photographers think that every photograph must be absolutely perfect. This is simply not true. Most often some of the best pictures are not perfect, because perfect can be predictable. However, in order to get those perfect pictures, any photographer, whether experienced or a beginner, must be patient and persistent. Eventually, taking perfect pictures will simply become a habit.
