- [[quote]] A primary use of gray cards is to provide a [[standard reference object]] for exposure determination in photography. A gray card is an (approximate) realization of a [[Lambertian]] scatterer; its apparent brightness (and exposure determination) therefore depends only on its orientation relative to the light source.
