Hi Folks,
I would like to know who makes the most accurate gray card for exposure purposes for film and digital photography. I have purchased a couple different gray cards, neither of them being a Kodak R-27 gray card and there seems to be a discrepancy in tones. For example, I have an 8x10" gray card and a zone system value finder card. When I take the zone system value finder and place it on top of the gray card, the Gray card matches zone 3 on the zone system value finder, instead of zone 5, which is what I would expect it to be, all things being equal.
Am I missing something? It seems to me that my gray card and the zone system value card should match in zone 5, not 3, so either one of these tools is wrong, or I don't fully understand the zone system. If that is the case, would someone kindly help straighten me out?
Is the Kodak R-27 Gray card set a reliable purchase?
Thank you very much for your consideration,
Don
