Re: color crossover in color negs, chemists advice needed.

You need to be more specific about the negatives on which you have encountered
these crossovers. Improperly "balanced" filter packs for internagitive film will
give these results. So will improper storage of film(too old, exposed to heat
etc) prior to processing. Simetimes problems with the replenishment of the
processing chemestry will also do this. Paul
