Choosing A Camera (part.2):

megapixels

Buying by only the megapixel rating will mean you will miss out on the other features of the camera ?portability, accessories, a good quality flash, but it is one of the most important considerations. Less than 3 megapixel cameras are suitable for basic snapshots; the camera will be small and good enough to take basic 'I was there' shots, but the images won’t be as clear if you want anything larger than standard 4x6 prints. Between 3 and 5 megapixels, you will find the best range of everyday use and vacation cameras ?you can fill your photo albums with shots from cameras in this range or use them as desktop images, as you will generally find the images are good enough that you don’t need any more and will be able to make good quality prints at a variety of sizes. From 5 to 7 megapixels, you will find serious cameras for hobbyists that want to explore photography as an art or those that are looking to stay ahead of the curve ?the images will take up more hard drive space but will be perfect for manipulation and printing out in larger sizes. Choose a camera of 7 megapixels or more if you are a professional and expect to be paid for the work you produce, as these cameras are overkill for casual everyday use, but ideal for professionals who need the highest resolution for larger prints, and more flexible cropping options.

zoom

Zooming is another important consideration with digital cameras - there are two kinds of zoom: optical zoom and digital zoom. An optical zoom factor is one that relies on the lens itself magnifying the light coming in, so that what is distant appears larger and closer in the resulting image. A digital zoom factor is one that takes the resulting image and magnifies it after the fact. Needless to say, an optical zoom factor is much more important than a digital zoom factor (and produces better quality results).
