Hi
I'm noticing that I'm getting scratches along the length of my slides. I don't think they're on every slide although I can only really see them clearly when there is a plain image on the slide ( clear sky for example).
I'd like to find out for sure if it's happening in the camera or at the lab.
Am I right in thinking that after making sure the camera is clean I could run a film though the camera and then immediately examine it for scratch marks. I know I'd ruin a perfectly decent fim doing this but at least I'd know if any marks did appear on the film surface it would definitely be happening in the camera.
