Just wondering what camera you're using that wouldn't capture to a
larger gamut? I can't imagine any pro-sumer or better camera that would
be stuck with such a small gamut. I know that with my S2 Pro I use
Adobe98 very successfully.

I'm not the most knowledgeable person on this list ( and that
statement
is up for "understatement of the year <grin>) but from what I do
understand, sRGB was developed by Micro$oft and HP (if I remember
correctly) for web colours on poor monitors. I just came back from a
digital photography seminar where the instructor strongly suggested
Adobe1998 colour space because it maintains the colour fidelity and
works well with almost every printer. So, it it doesn't "hurt" the
printer to use a larger gamut, why would you want to compress the
gamut
in your file before doing any work with it?
Right. My position is to carry across, from capture to final print, as
much
of the original colors as possible. And I'm sure that's everyone's
position
on this list and elsewhere. I mean, that's one of the goal of color
reproduction. So, if my original capture device does not "see" more
colors
than what fits into an sRGB color space, then, I'll stick with sRGB. I
won't
try to waste bits. But, as in the case of capturing IT8.7/1 and
IT8.7/2 with
a scanner, where the range of colors represented make up a color gamut
that
is larger than sRGB, then, of course, I'm not going to try to compress
the
colors into a smaller color space like sRGB! I'll use a larger gamut
destination space for that, like AdobeRGB or EktaSpace or ProPhoto or
anything that will preserve the integrity of the original colors.
Then, when
I finally need to commit the colors to print (make it inkjet or offset
or
whathever you want), that's when I'll submit the colors to a dose of
perceptual compression if I have very saturated colors. If the colors
are
not very saturated, like I find with typical skintones (please say so
if you
disagree!), I am going to lean towards relative colorimetric w/BPC. Why
compress then? I only compress if I have to.
That's my position.
