Malcolm,
From the 1Ds MkII manual p.48 (would imagine the same or very similar for
all models):
Auto: 3000-7000
Daylight: 5200
Shade: 7000
Cloudy: 6000
Tungsten: 3200
White Fluorescent: 4000
Flash: 6000
Custom : 2000-10000
all approx, degrees K
Why you ask?

Craig,
Many thanks, and sorry about wasting your time - I'd completely forgotten
that the info was in the manual(s) for my 10D and 5D.
I'm reviewing macro images of flowers taken in the very deep and narrow
Sottoguda Gorge, high in the Dolomites, where sunlight was largely not
present, and the weather was varying from dry and bright to mist and
drizzle. I used AWB for some, and tried Shade (which seemed sort of
logical) for some others. The "Shade" setting seemed fine when viewed on
the 5D's LCD screen, but back home the AWB setting looks truer, but not
quite right. From the above, Cloudy would probably have been better, and
with the °K info I can try out how "The Imaging Factory" Whitebalance filter
alters things.
(I could have shot in RAW, and did for some shots, but there were rather a
large number of alpine flowers to capture, and the 5D's RAW files soon eat
up memory. My image tank was back at the hotel.)
On a later flower outing, where I started to run into similar problems, I
used my Expodisc and Custom White Balance, with super results.
Thanks

Malcolm,
The "problem" with colour temperatures is that they are only a measure of
blue/amber.
Any green/magenta content can't be described.
So a mix of daylight and tungsten could measure the same as fluorescent at,
say, 4000K but would be totally different in colour.
Also, IIRC, ACR and RSE reported different colour temps of the same pic,
neither of which were the same as my meter!
Don't you just love "standards"!
