Interesting thought.I 'v decided to experiment(shhh don't tell the SO I've spent enough this month)and send a neg,6x7 B&W and a do a interneg on the(35mm) stuff in question.It'll cost a few schcels but could put my concerns to rest.
The interneg might not be a good test as every time you add generations you loose a bit of quality. A good R-3 or ilfochrome done on an enlarger would be a much better test. BUTCH Each man had only one genuine vocation - to find the way to himself. Hermann Hess (Demian)
