    For proper processing, if you fix before bleaching then the sulfite in an acid fix will act as a clear. However, you must also fix after the ferri bleach.

    New chart/v´curve

    I have now altered the way my densitometer plots to EXEL So you can have the curves in LOG/DENSITY axis. I have also changed to Fuji Hunt Chemistry and used Fuji negative control strips.

    The attached curve should give you an idea of what a color negative film curve looks like. This is an experimental coating that has severe defects causing crossover. I dug one out of an old file for you.

    Your reading of a step scale in R/G/B space should resemble a portion of this curve, either better in shape or worse. You should have 2 sets of 3 curves, one with one chemistry and another with the other chemistry. This is needed to make any sense of what you are describing.

    Sorry.
