I again reveal my ignorance:
I know that there is no way that a camera can get white balance right
without some information or assumptions, which can take four forms.
1. Set WB by taking an image of a white thing in the ambient light,
achieved with the Auto WB setting.
2. Set WB to the known or guessed color temp. of the lighting, achieved
with the preset fixed WB or direct color temp settings.
Both of these options can achieve rather good color balance in all but
complex mixed lighting.
3. Assume the scene averages out to gray, achieved with the Auto WB setting.
This is often going to give odd colors, generally whenever there is an
overall average deviation from neutral tonality.
4. Some manufacturers have introduced "intelligent" Auto WB, where the
camera compares color (and other?) characteristics of a subject with
stored samples to deduce what kind of scene it is, and set the WB
accordingly.
This is a P&S feature, not for pro DSLRs. However, I think the Auto WB
results of Canyon cameras are a simple form of this. DPreview has been
dumping on them for years about their poor Auto WB performance in
incandescent light. Given their general competance at other aspects of
image quality, I ask myself hwether this characteristic might be
intentional, to give the look of warmth most people expect and find
natural in such shots.
To date, the approach of #4 is not going to work for this kind of
camera, so there is no way at present to make Auto WB optimal for all
kinds of light. If I were making this camera, knew I couldn't make the
Auto WB work for all situations, and had to make a choice of what kind
of light to tune its Auto WB for, would I tune it for "arena lighting",
which, of course varies all over the place, or for relatively neutral
subjects? Given that this camera will be used for all kinds of different
purposes and that, as you suppose, people react strongly to skin tones
in people pictures, I would balance it to give its best results in the
kind of light used for portrait and event photography.
Now I know the SmartShooter skin tone test is flawed, in several ways in
addition to leaving out your beloved E-1. However, lots and lots of pros
who make (or try to make) a living taking just those kinds of pictures
and selling them to the subjects and their loved ones looked at lots and
lots of prints taken under limited, but controlled conditions. Voting
blind, they choose the 5D as the camera producing the best skin tones in
JPEG shooting at default settings.
So I propose that C did just what I would have done, as outlined above,
set default WB for the most WB sensitive application. I suspect that the
vast majority of people looking at the sports shot in SI don't notice
skin tones unless they are so far off that they start to make
determining race difficult. So how stupid would they have to be to tune
Auto WB for such situations? Having got that right on the 5D, why on
earth would they do anything but use the same set-up on the 1DIII?
Now back to those first 2 points, custom WB and fixed color temp
settings. We're talking pros here, right? People who are capable of such
things and might even visit the venue early to find WB settings that
work with its particular lighting in addition to preferred spots, lens
choice, etc.? And this is pretty simple stuff in a place with fixed
lighting, nowhere near as tough as some other venues.
If I'm buying a camera to shoot arena events for money, am I going to be
worried about something I can easily control beyond the needs of the
clients or about things like frame rate that improves my chance at the
money shot and iso performance that allows really high shutter speeds to
stop the action?
