I feel qualified to answer your question since I am a photographer and
well versed in using digital cameras,
PS CS is a more "interpretive" converter than "technical", but the
results are excellent.
I monitor APA digital list and photographers are split on what is a
"better" converter. Skin tones seem to be favored in canon raw
converter, workflow in Capture One and interpretive "hands on" in PS CS
Raw converter. I favor Capture One with PhaseOne and Fuji s2.
CaptureOne uses profiles, but it simply gets you in the ball park. I am
of the opinion that no profile will work 100% with cameras.
The only situation that gives you an exact usable profile is; say a
copy set-up with either flash or voltage regulated quartz lights that
are not moved and the same lens is used with same swings and tilts (if
applicable) every time. Even something as simple as adding a diffuser
to a light changes the spectrum enough to make the profile suspect.
Making a custom profile may still be a good idea as a starting point,
but you would need one for each lighting situation and to be a bit more
exact you could make a custom profile for each set-up or approximate
situation. Still PS will not allow you to use it.
CaptureOne i believe will.
My personal approach is to use the CaptureOne profiles (they have
canned ones for almost every camera) as a good starting point and then
tweak by eye with a good profiled monitor. In CaptureOne I do use
"exposure" and color-temp settings, but dont touch levels or curves,
but convert to 16bit and use PS for that tweaking. Interpolation up or
down is also best left to PS. The resulting file would be in the adobe
RGB 98 color-space.
Converting a tagged file from the Raw converter into a PS color space I
feel has associated losses.
PS CS Raw converter does not allow for profile conversion inside the
module. RAW in - tagged file out.
Hope this helps

The icc profile for my camera was made from an untagged TIF file
converted by canon raw converter. Can I use the Photoshop CS’ s camera
raw settings box in any way that will allow me to continue to embed
this profile before converting to an RGB workspace? If so please
elaborate.
