Any 1D (or other digital bodies) owners see this problem and have a solution?

Both shots were captured 1/8th second apart but the color difference
is obvious. No white balance bracketing in use. I have the latest
firmware.

This is not an anomoly ... it's a pretty common occurance.

Anyone see this in their digital body and have you found a solution?

I could be way off the mark here but what about the possibilty of rapid
flickering that occurs with luminescent lighting? ... It's too fast for a
brains to register but maybe not for a fast shutter speed on a camera

Did you try changing the film? If that didn't help how about changing labs?

Yes, use a fixed white balance instead of AWB. If you want it perfect,
shoot a grey card first, & take your colour temperature from that. (Or
shoot in RAW mode & fix the WB on the computer, which is what I do on my
10D.)

 

Possible ...

 

Already do that. I usually take a few shots first using the different
"stock" white balances and see if I like any of them. At this gym I
did actually use a white card image as my white balance.

 

It's the green colour cast on one and more accurate colour on the other that
makes me suspect this. I suppose the easy way to check would be to see if
this occurs on any any of your daylight or tungsten shots

It's just the lights flickering. As the lights pulse at 60hz, the
temperature of the gas in the bulbs fluctuates rapidly causing color
shifts. It happens all the time.

In that case, it sounds like your gym had mixed lighting. Flourescent &
sunlight perhaps?

On the flip side, the lights used in major league sporting arena's
(can't remember the name of them, Metal Halide?) use a gas in the bulb
that actually glows at the same color temperture as the filiment. So
when the light is in the off cycle the gas is still glowing at the
same temperture and you thus don't notice any disruption in the light.
This is why you can shoot at 1/1000th of a second and not have any
pesky dark frames.

The lights cost way to much for most colleges and minor league teams,
so it's way out of price range for almost all high schools.

Not in this one. There was another court in another room, same
building, that had some sunlight coming in but this main court had no
external light source.

 

Well, I can't seem to remember any daylight shots that showed the same
color shift. I'll have to check. Thanks.

 

Xenon, same as your flash Work the same way as well, except they
use the halogen to re-cycle the tungsten back onto the electrodes
like halogen bulbs do.

The bulb, and the constant current power unit. Prices are coming down
as volumes ramp up though.
