After a year and a half of efforts,I'm getting pretty good color matches
(to the slides I start with) with what I'm doing but nearly always, the
pseudo "red"filtered negative has to have density either added or
subtracted from some area, and registration errors are numerous.
I work from slides and make negatives to print from using a dichrotic
enlarger head - max filtration. There is some color bleed (especially
if the slide is contrasty) and sometimes masking is necessary.
I keep thinking there must be a better way, but maybe there is not.
