47 minutes

Jim O’Connell. The man seems to have a knowledge on photography that knows no bounds.I've been trying different developers for a while and have found the process a huge time sink. Half of me enjoys it and the other half just can't stand sitting around Agitating every minute. So, over a flickr on the Magnum group (no, the other one) where we seem to have all kinds of crazy discussions, the question came up about Rodinal by Jon about how long to develop for. Jim answers "For that, mix 1/100 with tap water, mix well, pour it in, shake it like a martini for 5-10 seconds and then let it sit for an hour before fixing and washing." but I remember hearing from either him or second hand that 1 hour didn't cut it when he changed to a new batch of chemical so he dropped the time to 47 minutes. So I tried it on 2 rolls of TMax 400 @400 and they "look" like they came out fine. Also tried it on 2 rolls of TMax 400 @800 and THEY look like they are ok too. The real test was to see if I could do a roll of TMax 100 and Tmax 400 at the same time. Result! I can't confirm this 100% until they dry and I've done a few scans but it's looking promising. I think the moral of the story is, if you have a question about B+W film dev just ask Jim. Stay tuned for results.
