Thanks in advance for any insight on this one.
I just got back a roll of 120 and some sheets of 4x5 from the lab and noticed that both the 120 and 4x5 had strange rows of banding going along the long edge of the negatives. The image with the fence is a detail (about half the neg) of a 4x5 and the other is a detail of a 120 (6x7) neg.
Trying to figure out if its the lab, shutter issues or possible film fogging. Oh joy!
Btw, both are Portra 400 (120 and 4x5).
