I've been loading my film wrong for two years and only noticed because of a light leak
So I got this old Canon AE-1 from a yard sale in Cincinnati, and for the longest time I thought I was a pro at loading it. I'd just drop the film in, pull the leader across, and close the back. I never had any major issues, just the odd frame that felt a bit off. Then, last fall, I shot a whole roll of my friend's wedding on Portra 400. When I got the scans back, there was this weird, thin orange line along the top edge of every single picture. The lab guy said it was a light leak, probably from the film not sitting flat in the canister. He asked how I loaded it, and I told him my usual way. He just shook his head and said, 'You're not catching the sprocket teeth, are you?' I wasn't. I'd been just laying the film over the take-up spool this whole time, not hooking it properly. All those slightly blurry shots I blamed on my shaky hands were probably from the film slipping. Has anyone else had a basic loading mistake that messed up a whole batch of photos?
