Janet, As far as I am concerned, that film wasn't worth much when it was new. : ( Yes, It could have been used in Dektol under red safe light to make enlarged negs. And since it was direct to negative, if you are going to try it make sure you flip you neg in the carrier so that it is up side down. This old it will probably have a bit of fog and always could have used a bit of help in he contrast range. I'd try some D11 or D19 with it and see what kind of range it will give you.

Hi Janet, You might look it up on the Net. It could be a direct positive stock. Frankly, any film that's 30 years old isn't worth the effort, time and chemicals to experiment with.

At a camera sale last weekend I bought a box of 4x5 Kodak Direct Duplicating SO-015 film. Can I use this film to make enlarged negatives? Can it be used under a safelight, although the box says "only in total darkness." Can it be developed in Dektol? The film is dated Feb. 1975. It may be useless, but it was cheap.
