This issue is currently ruining my photographic experience so i'd very grateful for replies. I've been using bulk rolled film in an AE-1 program. I've also used said film in a voigtlander and an EOS10. The problem is not present in either of those cameras so i can quite possible assume that it's the AE-1. But what is it?? Presumably people here like Mitica and HVR have seen just about every camera fault in existence. What is visible are these horrible exposed bars about three sprocket holes wide (this is 35mm...) They are consistently placed in the middle of the frame, offset slightly to the left.. however it does not appear on EVERY frame on a roll.. this pictures below depict the negs themselves and also a scan of one of the frames. Thanks so much in advance and i dearly hope this can be solved simply!
