I am fanatical about keeping dust from my film while drying, and have had consistent results up untill today. Somehow a series of 12 4x5 negs picked up some dirt or dust either from the darkroom or sloppy handling of film and holders. The kind of stuff that sticks and will not come off with an ant-static brush or compressed air. What is the recommended way to "re-clean" film. I could probably just resoak and agitate in photo-flo and try to a film sponge to carefully wipe of loosened dirt. Any other recommendations?(posted 8444 days ago)Thanks, Jim C.
