I've used the search function without any success so I figured that I just make a new thread for this. I don't know when it started but I've been noticing that I've been getting these underexposed edges on the negatives at the right side. At first I thought it was just the film curling while scanning but after further inspection, it definitely is on the film. I noticed that it only shows up when I set my shutter at 1/60. Perhaps a sticky shutter? But wouldn't that mean it would actually overexpose it? I use a Canon Old F-1 if that will help. Any thoughts...?
