Gray Card
What is a gray card?
Camera light meters see reflected light, but it is often useful to know the incident light (the light hitting your subject). With an 18 percent gray card you can get a reflected light reading which is essentially the same as reading incident light. Our gray cards are made from mat board. They have been painted to give results similar to an 18 percent reflectance Kodak gray card. This is equivalent to zone V. In the zone system, V is the middle tone half way between black and white.
