When we were discussing this issue in May last year, I did some
experiments with getting LCMS to handle all the gamma work. I posted a
patch which did this back then:
http://sourceforge.net/mailarchive/message.php?msg_name=20080504095335.GA3268%40earth.li
I also played around with a modified version of this patch, which
applied a profile based on the colour matrix but with the inverse gamma
of that selected in ufraw.
You would expect the gamma setting to then have no effect, but in
practice it had a very visible effect in the shadows. With gamma near
1.0 there was marked fogginess, which went away towards "normal"
perceptual-space gamma values.
It looked like the "fogginess" was a result of problems in LCMS, most
likely related to limited precision arithmetic. I found similar issues
in ArgyllCMS, which went away if I used its floating point math
options.
We discussed that a bit in this thread:
http://sourceforge.net/mailarchive/message.php?msg_name=481D7313.10009%40telenet.be
Graeme Gill of ArgyllCMS explained the issue for ArgyllCMS here:
http://www.freelists.org/post/argyllcms/icclink-G-and-source-gamuts-profiles,5
The explanation for LCMS is probably similar.
I never filed an LCMS bug because I didn't have a simple test case
program that didn't involve the rest of ufraw, but it's probably
straightforward to write one.
For the last year or so, I have been using an ICC profile for my Nikon
D50 which is generated by LCMS from the Adobe matrix, assuming an input
gamma of 2.2. I then use this in ufraw with a gamma of 0.45 (1/2.2),
linearity zero.
The program I used to generate this is attached, based on Rafael
Espindola's test code from January of last year.
