Has anyone else experienced light leaks around the edges of 120 J&C Pro 100? I processed a couple of rolls the other day that had been shot about a week prior. Since there is no tape at the end of the roll, I used rubber bands to hold the roll together until processing. I normally use black electrical tape, but ran out and some rubber bands were handy. Anyway, there was heavy light fogging along the edges of the last half of both of the rolls, the last couple of frames were VERY fogged, well into the image area. I got a bit concerned that maybe that batch of film was bad, so I took an unexposed, still in the wrapper roll into the darkroom and loaded it up, souped it in Rodinal, and it was fine, no fogging. My guess is that the pressure of the rubber band in the middle of the roll caused the edges of the backing paper to lift slightly and caused the fogging. Fortunately, the images were nothing of any importance, but I'm going back to using tape from here on out. Those lovely 120 film cans that the film is now packaged in should also eliminate that problem with film that sits around for a few days before processing. BTW - I compared the backing paper of the J&C 100 to the backing paper of Tri-X. The post film portion of the Tri-X backing paper is about 3 inches longer than the J&C 100, giving at least a full turn more at the end of the roll. I love this film, but I'll sure be careful to keep tape in my bag at ALL times.
