The Difference Between Digital Camera And Film Camera

Basically a digital camera is a device use to capture pictures without the use of film. Unlike the conventional camera, it does not rely on mechanical and chemical processes. Since the images captured are in electronic form, this is a language recognized by computers. Although the image looks exactly the same as that of a normal photograph, they are stored as pixels.

Many similarities exist between the two types of camera because lenses are still required to capture light just the same as a film version. The only difference between a digital camera and film cameras is how they capture this light inside the camera itself. A charge couple device is the light capturing device in the quality models that is used to convert light into electrical signals and as far as the user is concerned, an image is saved just like an ordinary device. Less expensive cameras us a complementary metal oxide semi-conductor or CMS device which does the same work of capturing an image and although some believe it could replace the CCD, this is not likely.

The CMOS device is this reason that many models have come down in price so much as they are easier and cheaper to produce than their CCD cousins. A digital camera works where millions of tiny solar cells, each of which forms a part of the whole image; both CCD and CMOS do this task using different methods. If you find yourself in the market for one of these marvelous cameras then some useful information is detailed in this article. Look for models with over 6 megapixels and you won't go far wrong as they will provide decent images; they can also provide prints that are larger without any degradation.

Many people rave about a digital cameras zoom power but the image is being artificially magnified so always try for an optical zoom even if it is one with only a low magnifying power; portrait shots that require 'framing' are so much easier with a an zoom facility. Today's nickel metal hydride rechargeable batteries are very powerful and last for around a 1,000 charges so always use these if you want to save money. most models come equipped with some sophisticated software that can create interesting shots; functions like those listed here for instance:

*Macro (close up shots)
*Continuous shooting
*Self timer

You will also need something to store the captured images on especially with the high megapixel models available today. Although larger storage cards have plummeted in price, a 1GB card should be enough for most peoples needs; some cameras won't accept very high capacity cards anyway. Unless you intend to use your camera for serious photography there isn't any need for a bulky very high specification version.

There is no longer any need (even for keen amateur photographers) to carry around large, heavy models if you don't have to. These are just the basic things you have to look for in a camera when you buy one. Digital cameras have very quickly become the way to take photos and have reinvented photography for those who had no real interest before there introduction.
