In a previous posting I crowed about my clever way of processing 9x12 film in a Beseler Unidrum for 8x10. Well, now I guess I have to eat a little of that crow. The last batch of film I processed was a single piece of Efke 100, and while the film was processed well, I had a problem with the back side of the film. There was a streak of the (I'm guessing) anti-halation coating on the back where the film was stuck against the side of the drum. This was not a fatal problem; a short rinse in plain water removed the remnants of the coating. This is an annoying problem, though, and one just as likely to occur with other sizes of film in the drum, since there's nothing to keep the back surface of the film from sticking to the sides. Should I just learn to live with this problem? I suppose I could incorporate a post-rinse into my processing, using trays. At least I wouldn't be shuffling sheets in the tray in the dark, which is pretty much the whole reason for using the drum in the first place. Or is there another trick one can use here?
