I just got back from the lab my first 2 rolls of 120 using a DAYI 6x12 film back. Every image had the same problem.
Each image has a 8mm section that is clearly underexposed compared to the rest of the image. This section is located on the far right of each image. This section that is underexposed has a sharp line, it isn't a fuzzy transistion. Directly next to this sharp line of underexposed film is evidence of some sort of light leak - next to the sharp line in all images it appears the image is overexposed for a few mm, though the transition is back to the rest of the image is smooth, no clear line is visible. Most images are not completely blown out in this area, and in some it's hardly noticable. There are however a couple taken when the sun was higher that have a good 10mm section completely blown out to white and then pink fringing before returning to the image.
I'm a bit perplexed where to start with this as although it seems there is a light leak, I can't see how one small section of the image is also clearly underexposed each time and why there is a firm transition at this section.
I'm still waiting to get my 4x5's transparencys back from the trip, but the last set I took were fine and showed no evidence of this sort of problem (fingers crossed it is the film back causing the problem - I hope all my 4x5's from the trip aren't like this as well!)
Unfortunately I don't have access to a scanner at the moment so I can't show you scanned images, so it may not be possible to identify the fault., but any suggestions would be great
