Color control
All digital cameras offer an automatic white-balance setting that calculates the right color balance for your shot, but the results can be erratic. Look for models that let you select among white-balance presets for particular types of lighting, such as sunny, cloudy, incandescent, or fluorescent. If you'll be shooting a lot under fluorescent light, look for a camera with presets for all three types--or at least make sure that the fluorescent setting on the camera you choose matches the type of fluorescent light you'll be using.

Manual or custom white-balance is the most dependable because it lets you take a reading from an area that you want to appear as pure white in your picture, then use that reading to calculate the color balance. Advanced photographers may find white-balance autobracketing and compensation useful. The ability to adjust color saturation or select from different color modes is an important tool for serious photographers as well.
