Hello all, I'm a new Leica owner, I have a Leica iiif that I've had for a few months. I've just had the second film through the camera and have noticed some artifacts that appear on every fame of the film. They weren't on the previous film I had processed. In loading that film, I had problems getting the film (with a correctly cut film leader) and had to remove it and reinsert it. Have I damaged the shutter curtain? I can't really look just now, because there's a fresh film in the camera. Thanks for your advice.
