Digital Cameras come in two basic types, compact, pocket size or Digital Single Lens Reflex (DSLR) here is a short résumé of both, it may help if you have not bought a digital camera or are thinking of up grading to a DSLR.

Compacts are usually small pocket size units that are fully automatic, have short zoom lens and a screen on the back used for both taking and viewing the picture.  Very simple to use and ideal for beginners, the automatic exposure adjusts for different light conditions, the auto flash works in low light, and the auto focus sets the distance, no more to do except frame the subject and press the button.

DSLR's are for the more enthusiastic or keen amateur photographer, although they have the same auto settings as the compacts, focus, exposure etc, you can override some or all of the automatics.  The main difference is that they have a) interchangeable lenses so you can put wider angle or longer telephoto lenses on and, b) via a prism or mirror system you view through the lens, thus seeing exactly what you are taking and at eye level.

Today's Digital Cameras are easy to use, lots of automatic features which make picture taking simple and enjoyable, but difference between a "snap" and a photograph is vast.  It's easy to show someone a picture of your child but when you want a good "photograph", one to enlarge and hang on the wall you are prepared to pay a professional so why not learn even the basics and produce better pictures your self?
