, for testing, but not for doing actual exposures. If actually needed for exposure, I'll use the white card in this set.
I am for an accurate neutral gray card that has true 18 % reflectance. I want to use it to accurately set correct exposure. I may vary the exposure one way or the other for creativity but I want the truely accurate initial exposure. Does anyone here use a gray card to set or check for accurate exposure and if so, could you suggest one or more good reliable ones? Any help will be greatly appreciated.
