A gray card is an object of neutral color which reflects a certain amount of light. It is used to solve two color related problems in photography. One problem is a so called color cast (~ hue tint) in images caused by different illumination conditions and the cameras (in)ability to neutralize it. The other problem is the lack of a reference point for managing exposure time (amount of light captured), to prevent an image turn out too dark or light.
