Maybe this should be in one of the film forums, but here goes: I recently shot four rolls of Fuji 120, both B/W print and color reversal. All four had narrow light leaks, edge-to-edge, evenly spaced along the length of the roll. The obvious suspect was the little window on the back of my Kodak Brownie #2 Autographic. But then I realized that one of the rolls was shot in a roll-back on my Speed Graphic. I always load in subdued light, so that shouldn't be the cause. Anyway, I'm sure I shot 120 as a kid, and I don't remember any problems then. So, question: Are the light traps on 120's less than effective, or am I missing something? My only other thought is that the lab that processed them is screwing up, which I doubt. Any suggestions? Thanks.
