Hi Eric,
Thanks for responding.... I take it the restrainer is the Benzotriazole?
So 7-12 min in stock D-76.
I seem to remember reading that old films loose some of their contrast,
hence their softness (?) So wouldn't the longer development time
(12min) help what contrast is left?
Cheers,
Bogdan

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.

*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...
Cheers,
Bogdan K
