Alan.... Many of the so called generic or "supermarket brand" are made
by major manufacturers (konica, etc.) It sounds to me like your
scratches and muck problem is a Laboratory problem, not a film
problem... try to find a good custom lab where they use a dip and dunk
processor as opposed to a roller transport processor... the difference
is that with dip and dunk, the film is hung from a hanger and weighted
so it can be dipped into and out of the process chemistry without any
thing such as rollers touching it... roller transports are ok if they
are meticulously cared for (which most consumer labs don't) but they
still have their problems... a professionally run dip and dunk line is
absolutely the best way to process your negs... you should see a huge
difference in the scratches and muck problem.
