David,
<<Using PS CS's camera RAW I open my Canon EOS 10D images. I have been
choosing ProPhoto RGB. I keep everything in 16 bit. Then the file is
sent to my Epson 9600 with Ultrachrome inkset and matte black ink.My question
is, what am I loosing, if anything in the final print, by
being in ProPhoto RGB the entire time? Should I save the RAW file in
Adobe RGB 1998 instead? I don't believe the Epson 9600 can print the
gamut of the ProPhoto RGB.>>
I do basically the same thing and after much testing I've come to the
conclusion that this is the correct workflow. Depending on the paper type and ink
combo, the Epsons can have a color gamut that is significantly larger in places
than AdobeRGB1998. If you are shooting high colorfulness scenes or making big
moves in PS, then parts of these images can easilly fall outside the
AdobeRGB1998 gamut. You can easilly test this by proofing your ProPhotoRGB images in PS
CS using Proof Setup and the Gamut Warning. If you find that none of your
finished images exceed the AdobeRGB1998 gamut, then working in 16bit ProPhotoRGB,
while safe, is overkill. If in doubt, stick with your current workflow with
one significant modification - make sure you have Proof Colors on, the correct
printer profile specified in Proof Setup, and Gamut Warning on. Because
ProPhotoRGB has a gamut greater than the Epsons, this modification will help you keep
your images/edits printable.
