Digital BW, The Print

Good questions, Antonis.  I will have to approach this in a more structured
way.  The PS color space (Adobe RGB 1998) and the Epson print space (Epson
2200 EEM MK, no color adjustment) are the same.  The files are RGB (Portra
b&w C41 film, which scans with a slight color cast, so converted to b&w in
PhotoKit).  The computer is a PC (Windows XP).   I didn't think to test both
8 and 16 bit files.  What I did was start with a 16-bit RGB scan that I had
used to make an 8-bit print, and did similar contrast adjustments with CS,
only now with 16-bit layers.  After drying, the prints (EEM) are pretty
green under daylight, but fairly neutral under tungsten or fluorescent.  I
would have thought that if the PS eyedropper tool is showing me that RGB
values are equal, and I print on the same paper with the same profile,
Photoshop would not influence the print.  But maybe not.  I'll work on it
some more and report back.
