Hello Paul, is there an step by step explanation somewhere, how to do that
without spoiling everyting? I would indeed make the "N" curve a very little
but cooler without getting it near the cool curve. At which color to start
and how to edit it exactly?

I will have to explore it more exactly, but my theory was that according to
the lightness or darkness the pront uses more of  the one or the other ink -
one can see it easily on the file with fancy colors (the curves applied for
pronting). My understanding of the phenomenon was that the 3 colors dont
have the same grade of warmth, so according to which one is most used in the
print it seems warmer or cooler - but I didn't study it systematically. The
difference however seems clear. I just finished printing several hundred
photos from my India trip and some seem to be made with another inkset, even
when the N curve is applied.

Or might it be that I do thewrong procedure? Is it absolutely necessary to
first convert to BW and then back to RGB? It might happen that I sometimes
just apply a channel mixer (grayscale) but dont really convert to 8bit BW
and back to RGB then.
