Unfortunately you need to test to see what step the fogging is happening.
Running an unhandled & unexposed roll would check for leakage from
before you received the film. Not a great choice as you have to use
up an expensive hard to find product.
loading & unloading the camera in complete darkness for a roll or
two might give you some clues about what's happening as well.
Checking for light leaks in the camera would be wise.
If you are using 5" aerial film without antihalation backing, you'll
have great many more problems with flare.
If you are using a thick film base like a sheet film base it will
want to unwind more, and may not be as tight as you think on the
roll. It will tend to unwind itself without constant pressure to keep
it tight.
What kind of film is it? Jamie Young from Madison, WI
