I have two rolls of 120 Fujicolor NPC 160 that were left over from a project a few years ago (2002 or 2003 I think). It's been in a refrigerator ever since. It's "pro" film and so does not have the preservatives that consumer film has. I'm wondering if it's any good. I've heard that the primary effect of aging on film is a change in film speed, and you can get good results if you allow for this change. If this is true then I suspect that the direction of the change is for the film to get slower. I thinking of exposing it as ASA 100 or 125. Comments?
