Hey all, wondering if any one could shed any light on my situation (no pun intended). I recently bought a Pentax 67 and have been loving it, the first two rolls were some of the most immaculate negatives i've ever gotten back from the lab. However I picked up two more rolls yesterday and there were light leaks along the edges of everything! Weird ones too, you can see in the photos below that you can actually see numbers and symbols, almost as if the backing paper was somewhat printed onto the negative? I've never seen this before and am pretty confused because no harm was done to the camera in between rolls, it was also a matter of like two days between shooting the good and the bad. Any thoughts? Thanks in advance!
