Hello everyone, I just developed two rolls of Tri-X yesterday in R90 1:50. This shot is from a Leica II which was performing fine a few months ago. Notice how the image is dark in the middle. It is a bit more pronounced in some photos, and absent in others. I did two rolls at once, and the roll from a different camera didn't have this at all. I'm no shutter expert (besides wrecking them) but can anyone tell me how a horizontal focal plane shutter would cause something like this?
