Hi, I have decided to give Stand development a try - I have a roll of HP5 pushed to 1600 that I want to use as the first cab of the rank. I also have some Rodinal. What starting figures should I use? From my research, I have been found 1:100 & 3.5ml per roll for 1 hour. Is that going to be sufficient, or should I change the dilution and/or development times? Also, what about temperature? Is the standard old 20deg C as good a starting point as any? Cheers.
