Digital cameras also make sense in situations where the image quality of a photo is not critical-publishing on the Internet, for example. They are usually found with a zoom lens and a series of automatic exposure settings. A flash is often available to enhance a low light situation, and there are even cameras that can take a series of pictures continuously with one press of a button for action shots. However, the similarity ends with the picture processing. Because the pictures are stored as digital data instead of film, one critical measure of picture quality is resolution.
Resolution refers to the number of dots used to compose the picture.
Even greater resolutions are preferred if you plan on enlarging and cropping the pictures. Another factor affecting image quality is the digital camera's bit depth. This refers to the rang e of color that can be captured in a given pixel. Higher bit depth translates to greater color sensitivity. Look for a minimum 24-bit camera to ensure an adequate range of color will be displayed.
