Hello, I use my old 4x5 camera more and more and I was thinking trying to test my system. I have done some reading and I would like to go for "the contact sheet test" as described by Barry Thornton or the "second" test described in Way Beyond Monochrome II. In short, they both come down to define the "minimum time for maximum black", then see which exposure gives the best result to render zone III detail to define EI and then do some development test to define the development time. Barry Thornton method uses contact sheets and WBMII uses enlargments to do this. Is there an advantage in each of these methods that the other does not have ? Thank you !
