Blotches on edge of 120 film
Hi! This is only my 2nd C41 roll I've developed, the first was a 35mm roll and it went perfectly. Using Cinestill's C41 kit and a Patterson tank.
On this roll, I noticed on one of the first negatives I scanned that there is a slight blotch on the left-hand side of the frame. When turned positive, it appears bluish. I also noticed a similar (but fainter) effect on the second frame.
Attached a photo of the negative and positive, also confirmed visually the same blotch is on the actual negative (just looking at it in my hands).
Any thoughts as to what might cause this? loading issue? bubbles during development?
