Horizon 202 Banding
So I have had the 202 for a few months now, I just came across a roll that i shot a few weeks ago and see that there is banding on most of the frames of that one roll. (this was an expired roll of tmax 3200 if that matters) The rolls that I have shot since then seem to be fine, (ill be processing an other roll in the AM that I shot today) Assuming this next roll is fine my question is this: what caused the banding on this one roll of film? Is a CLA in order? Any help would be appreciated.
