I shot some HP5 which I rated at 200 ISO. The exp. range was about 7 stops. I placed the shadows on zone three. I want to use Rodinal as a compensating dev. t o compress the range to about 5 stops. Questions: 1 Is 1:100 a good dilution ratio for this? 2 What is an approximate time for development? 3 Also, I exposed some Agfa 100 at 64 ASA - same kind of exposure range. What would be an approx. time for that? 4 I have a daylight tank which holds 6 films and takes appox 1100 ccs. I read somewhere that there may not be enough dev in a dilution of that strength for th e film area. Is this true? If so how do I make a high dilution but make sure th ere is enough dev? Only do three at a time? Many thanks to everyone in advance. I would also like to thank everyone who con tibutes to this BB. It has helped me tremendously. Yaakov Asher Sinclair
