Michael, Thank you so much for the detailed response. I am hoping that you are right, and that WAS just the ending strip of the film. I was not monitoring my film gauge, unfortunately. I just remember taking the cartridge out, thinking I'd have shot half way or 3/4 into it, compared to prior experiences with other film types. Maybe like you said, it was short loaded. Today, i will shoot a test roll of B&W on the Nizo Professional, and see what happens. I hope it was the film stock and not my cameras. I'll run my tests and let you know what happens.
Thanks again Michael.
