Cross Processed Negs + Enlarging In Color Help

Cyan need not be touched unless you run out of magenta and/or yellow, or unless you want to dial in very precise amounts of neutral density. Cyan works opposite the other two filters, since it is cool and the other two are warm; another reason not to use it.

FWIW, on my enlarger, I require cyan filtration, along with increased magenta and yellow, because without that my printing times are too low, even with the lens stopped all the way down. I also like to start with some cyan because that makes printing a complete color ringaround a bit easier; I can subtract 5 or 10cc of cyan rather than add 5 or 10cc of both magenta and yellow.

Nevermind, I already know.

FWIW, I had to employ cyan filtration for the first time ever today. The electronic Beseler color head I was using does not let yellow and magenta go below a certain level, so I had to add cyan to lower the Y and M numbers. Even though I turned up the cyan knob, the only thing it did was lower the numbers for Y and M. The cyan LCD stayed at zero.
