The gel that contains the active ingredients probably doesn't freeze/separate until it is noticeably below freezing. Testing is in order. The problem is that the chemicals that do the developing are in a gel. You're not just freezing the film (and paper) which can stand freezing, but you're freezing the developer/fixer in solution. When you freeze stuff like this, different components freeze at different temperatures and separate, and then the ingredients after thawing either are separate from the those they should be intermingled with, or are no longer in solution. - -- * Henning J.
