I may have done this wrong, I apologize I’m new to this site. However, I’m trying to figure out the source of my film processing issues; The last 3 rolls of Black & White film I developed I notice scratches along the edges, outside of the sprocket holes. Basically, where the name of the film usually shows is either clear or scratched.
The first 2 times I used a plastic tank and saw Discoloration and black marks on the outside edges and now, I tried to use a stainless steel tank and I’m seeing scratches.
i use a Nikon FA that normally has had no issues when I get rolls professionally developed so I can’t tell what the problem would be. The frames themselves come out fine, so the issue is cosmetic I think but I’m shooting for perfection if possible. If anyone could diagnose this, it would be awesome.
