I've been keeping quiet because i didn't want to contribute to a
flame war, but I can't sit by and let the debate be characterized as
one between color profiling and color correction, or as between
"pleasing" color and "accurate" color.
The debate, such as it is, is between two PROFILED approaches to
handling color in raw conversions.
1.) Convert using a single custom profile as source, as in the Phase
One Capture One/ColorEyes 20/20 workflow
2.) Convert using the white balance tag from the camera to set the
correct interpolation point between two generic profiles with
different white points, as in Adobe Camera Raw.
My experience has been that neither method is more or less likely to
deliver accurate color. (Of course, accurate color that isn't also
pleasing is generally not commercially useful.)
I just bought a Canon EOS 300D, and with either an auto or a custom
manual white balance, I'm finding that ACR nails the color dead on. I
generally have to make tonal adjustments, but I don't believe that's
unusual in any workflow.
So please let's lay to rest once and for all the myth that ACR
demands more handwork and produces less accurate color than other
workflows. Depending on how close the specific unit you're shooting
is to the one Tom Knoll profiled to add ACR support, you may have to
make greater or lesser use of the Calibrate features in ACR 2 to dial
in your specific camera, but in two of the three cameras I've used
extensively with it, I haven't had to resort to the feature at all.
Others' milage may, of course, vary...

Oh please don't take this off line!
I am very interested in hearing this debate.
I suggest that for art reproduction, with fixed lighting, the profiling
method is a good place to start.
For "pleasing" color rather than "accurate" color the correction method may
be better in some cases.

Instead of continuing here, and since you are local why don9t we use this
as
an opportunity to put the methodology I am speaking of to task?
Id rather do than theorize here.
Please feel free to contact me when you have a moment.
All the best
