Advice on vertical bands appearing on negs at random. (ETRC Bronica 120 back)
I would really appreciate some feedback and help identifying the issue here. At first I thought it was some kind of reflection off the prism or filters, but I have tried both on eye level and waist level finders, removed the filters and shot with the lens hood to try the process of elimination, but the problem still persists.
Can anyone help me identify why I get these thick bands at seemingly random exposures? out of 15 exposures, about 5 appear with the band at not particular order, seemingly at the exact position on the neg
Thank you so much
