Photography Gray Card
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
There are several good reasons to buy a professional
gray card but if you are in a hurry or want to
experiment you can also print a gray card first.
Consult your camera's manual ("manual white balance" and "exposure time") for instructions on how to use a gray card.
