you clipped off John's quote. anyway, straight AWB conversion with default
Photoshop CS settings, except for possibly exposure compensation, of the
color calibration charts taken in daylight with direct sun on the chart,
gives extremely accurate color. delta E average around 3.8 and a sigma of
4.6. these results are well above average for DSLRs. Photo Laboratory gives
delta E around 5.6 and sigma of 7. these are about average results for a
good camera. these are from converting the same image files with the two
programs and using AWB with possible exposure compensation and no other
adjustment. making adjustments improves some things and makes others worse.

I was a little confused by John's assertion below. In the PSCS Raw
Converter one need only go to "calibrate," and the red hue and saturation
can be controlled independently of the other colors before conversion. I
can't think of a single attribute that can't be dialed in during conversion
in PSCS. About the only thing I ever do post conversion is a bit of
shadow/highlight control.
