I have no idea how roll film is commercially developed. I was
hypothesizing the roll being drawn through the chemicals and getting
stuck in one place too long. Totally in my head and without any facts
to support me. Regardless, some sort of processing error seems much
more real to me than two adjacent images sharing a common defect that is
visible only on about 1/3 of each image and those areas being adjacent
to each other. What in the camera causes a flaw to appear on the right
third of an image and in the next frame to appear on the left side?
So far no one has even commented that they see this adjacent image
problem. Am I imagining it?
