I teach enlarging negatives the old fashioned way. My next class is with Julio Galindo at his school in Mexico this June. The best film I've come across is some that expired in 1968. It is labeled Graphics art film, and is a Kodak product. You want base fog when making an interpositive. The film that is that out of date, comes nicely prefogged. Janet the film you have is not one you can use under safelights. Aggie afterswift@xxxxxxx wrote: 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.

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. Janet Ness = --------------------------------- AOL now offers free email to everyone. Find out more about what's free from AOL at AOL.com.
