Okay, I posted once before on this and thought I might have a solution, but I was wrong. I keep getting very faint scratches on my negatives that show up on enlargements. The scratches don't appear on every negative so I don't think it's an in camera issue; I could be wrong. I have cleaned all accessible areas in the camera just in case, but everything is pretty immaculate inside. I develop in a single reel tank and am very gentle throughout the process. Once the roll is developed, stopped, fixed, and washed I hang to dry, never touching the film (aside from the very end of the roll). I do not have forced air/heat in my house so dust is at a minimum. The film hangs undisturbed in a closed room until dry. Once dry, I cut into strips, one at a time, and lightly dust with an anti-static brush to ensure the negatives are as clean as can be going into the sleeves. They are then stored in a sealed box and receive no trauma whatsoever. At printing time I do not drag the negative across the carrier, which is smooth anyway, so I don't think the problem occurs here. I didn't have any such issues until a roll processed on 12/17/06. After that, each roll has a couple of scratched frames. The only thing that changed in my process is the weather. My next step is to skip the Print File sleeves and store the negatives elsewhere. Any ideas on how I can diagnose the problem? I'm losing some good shots because of this problem. Thanks.
