Working in a museum I need to supply images of our paintings for quite a
number of different outputs.
So we start with a "master" scan of a painting, correct the color against
the original (preferably in Lab), and then make derivatives from this master
file for offset, web, inkjet, laser, museum's visitor display etc.
What would then be the optimal working space in PS6 for the "master" image,
to ensure the minimal loss of detail upon subsequent size & mode & gamma
changes?
Are there any particular advantages/disadvantages in using linear workflow
(gamma 1.0) for the master file?
Is it true that the loss of detail upon Lab-to-RGB (or else) is less in
gamma 1.0 than in any other?
I guess it's stating the obvious, but the choice of film is the first
and not the least important decision.
If you want a workflow for professional archival use and where the
digital original remains unclipped using the full film gamut, then
you're headed for 16 bit Lab.
16 bit Lab and more specifically 16 bit Lab TIFF will I hope be
sorted out in conjunction with the update to the ICC spec, to
Photoshop for OS/X and to scanning software for the Mac.
For archival museum use you should look at the standards and proceed
from them to build your shopping list.
