Setting up your camera is very important to achieving the best product possible. There are four main factors one needs to be aware of when setting up their camera. These four factors are compression, resolution, white balance and sensitivity. A digital camera allows you to save in three different formats, depending on the model of camera you have. RAW, JPEG and TIFF. RAW is the cameras proprietary format, which records all aspects of the shooting data, and contains as much colour and detail information as the camera can provide. Its downside is that it can only be used by individuals who have the right camera driver software, which will allow you to print pictures. The JPEG format examines the image and simplifies it by throwing up to nine-tenth of the file size away. The advantage of this you can fit more memory pictures on your memory cars, however, if you are planning to blow up the picture, the image may appear blocky.
There are two types of lenses one can choose from. They are fixed and zoom. Fixed lenses are mostly found in inexpensive cameras which do not allow you to zoom into your image. Therefore, in order to get a closer look at the image, you are forced to physically move closer. This could be very tricky when shooting a wedding. With a zoom lens, it is permanently attached to the camera; however, it still allows you to zoom in on the subject for a tight shot or zoom out for a broader image.
When your battery runs put at the most unexpected time, that could be very bad when your in a middle of a wedding. Fortunately, many popular digital cameras use alkaline. Only downside to them is the life expectancy and replacement cost. Ni-cad batteries are expensive initially but in the end pay for themselves, for they are rechargeable and can be used over and over again. Downside to these batteries is that you will only be able to capture a few shots before having to replace your batteries. The second problem with Ni-Cad is they can develop a chemical memory. A chemical memory is the number of pictures you are able to capture before recharging. If you recharge your Ni-Cad battery before they are completely discharged, the next time you go to use those batteries you will get fewer pictures before the batteries need to be recharged again. NiMH, a third type of battery has been introduced with better features. This battery has a much better battery life span without the concern of chemical memory. These batteries are too initially expensive but pay fort themselves. Another advantage to this new battery is that it can be fully recharged within only one hour.
Megapixels are the multiple of pixels. A megapixel (one million pixels) primarily determines how much detail and how rich your image will be. Megapixels also determine how much a picture can be enlarged by without distorting it.
