Umm no feedback from the OP.
Could be a lot of things. For me, it mostly happens on the development process, either before or after development. Sometimes I'm to rough when loading film on the reels and sometimes when I squeeze the film. Don't normally squeeze film but sometimes my mind is absent, so squeeze before I realize
.
At leas for me, its rare for a camera to scratch film. Have used about 15 cameras lately, including Leica, Rolleiflex, Canon, Nikon, Fujica and SLR Rollei's and none had scratched my film.
