TIP
If your camera doesn??™t have a digital noise filter, mount
your camera on a tripod, and shoot several pictures in low
light without a flash. The ideal test of a camera??™s ability to
deal with digital noise is a night scene with bright lights
and a dark sky. Shoot the first picture at the lowest ISO
setting, the second picture at the next highest ISO setting,
and so on. Download the pictures to your computer, and
preview them at 200 percent magnification to see the ISO
setting at which digital noise becomes visible.

Cope with Lighting Conditions
When objects are viewed in different lighting conditions, the three primary
colors (red, green, and blue) exist in varying proportions, depending on the color
temperature of the light source. As the color temperature changes, the color cast
changes. When a color temperature is high, there is more blue. When the color
temperature is low, there is more red. The human eye compensates for color
temperature.
