I think in discussions of old film processing the adding of a restrainer was not recommended. There will be fog more than likely but a restrainer probably won't help. a 7-12 minute development will probably be OK. e ________________________________ From: Bogdan Karasek <BKarasek@xxxxxxxxxxxx> To: pure-silver@xxxxxxxxxxxxx Sent: Sunday, February 5, 2012 2:58 PM Subject: [pure-silver] Developing Univex ultrachrome No. 00 film Hello all, A neighbour recently gave me a box filled with old cameras and film. Inside, I found 4 rolls of Univex ultrachrome No. 00 film and it is marked EXPOSED. What information I have been able to find states that it was made in the 1940 by Gevaert of Belgium for Univex. A label on the box says that it should be developed by 1949. Since I can't let sleeping dogs lie, I want to try developing the film. I have no idea regarding the film's ASA and no info is forthcoming on the Internet..... So.... Anybody have a clue as to the possible asa of this film and what would be the best way to proceed with development... All ideas are welcome. I have four EXPOSED rolls. and I still have my 3.5 gal tank of stock D-76 which I was going to dump but decided I could develop the film by dunking it in the tank. Probably have to add Benzotriazole to the D-76..... how much per litre/gal? Anything else I can try? I'll do one roll at a time, so I have 4 trys at finding the right combination to adequately expose one roll of the film. Thanks for any ideas...
