Re: RE: Gum / Van Dyke online

Thanks,
That's why I am looking for some help.
Yes, the van dyke process changes a lot the gum colors.
With cyano there is no problem, Wang article works perfect
(http://unblinkingeye.com/Articles/3CG/3cg.html)
But can it be done with Van Dyke?
I mean changing the "RGB" to 3 new primaries and one is a the Van Dyke-
define on photoshop as a R(75) G(34) B(32)? or whatever but we need to find
the other two gum colors (color theory).
Does it make sense to you?

mention that for my combination prints I printed both the positive and the
negative of the image (one in VanDyke and the other in gum). I never tried
to get "full color" using the two processes. I'll be interested to hear
what you do.
