White Balance

The image sensor in a digital camera does not "see" light the same way that film does. The sensor just receives light, generates an analog charge that must then be interpreted by software to digital pixels. This gives digital cameras the ability to adjust color in camera. What white balance allows a digital camera to do is to calibrate all the colors based on the color White. In finding a reference white, all other colors are adjusted accordingly. The better digital cameras allow you to calibrate the white balance using a white (or gray) card. Ensure that your digital camera allows you to select different white balance setting for different situations, such as outdoors, cloudy, fluorescent, and tungsten.
