Book Summary Information

Book Reviews of KODAK Gray Cards (Black and White Photography)

Book Review: True, but not the whole truth
Summary: 1 Stars

Yes, cameras are set to determine exposure based on the reflectivity of 18% grey. That's because this is the reflective value of common objects such as people, grass, bricks and grey concrete.

Grey cards are helpful to determine the correct exposure when you're photographing something brighter or duller than this 18% grey. For example, in snow, on water, or in a really dark environment. But, they're no good if you can't alter the exposure on your camera. Sp, if you don't have an SLR camara, don't bother.

Plus, for a lot less money, a brown paper bag - like the one you used to get your school lunch in, or even the hand on the end of your arm, will give you exactly the same result!
