While on vacation in LA I stopped by Freestyle and picked up some film. Among it was some Tri X and Arista Edu / Fomapan 100, I shot a few rolls of each while down there.
Both of the Fomapan rolls have an odd line through the frame. The height of the line changes frame to frame and isn't always straight. The difference is fairly consistent and the line is visible, though not as much, between frames.
While I'd normally default to user error (developing, etc) on my end, a light leak, etc I can't think of anything that would cause this specific default due to how specific yet irregular it is. The issue is plainly visible on the negative so it isn't a scanning issue.
I have at least one more roll to develop but expect to see the same issue on it.
No issues with Tri-X or Acros shot on the same trip in that camera. All home developed.
Beyond an emulsion coating issue which seems unlikely, any idea what else could do this?
(The spots under the line are on the negative as well but aren't consistent frame to frame)
