Here's a question where I know what causes it but I don't know how to deal with it. There is a discussion about this on a photo site but I no longer post there.
In that debate the responders say it's the nature of fluorescent lights to "flicker" causing white balance or color shifts. For me those shifts go from brown to yellow. They also say it's more noticeable at higher shutter speeds. Their solution, shoot at slower shutter speeds.
In some of the basketball courts I shoot in that's not possible. I can put my D300 in burst mode and the exposure (color) will be different for each shot of the same subject shot back to back. The funny part is that I never noticed it until I did the firmware update last week.
Last year I shot basketball on the WSU campus with the same camera with no problems. The first home game this year is when I noticed it. Mt initial thoughts were they changed the lighting in the facility.
Any ideas?
Thanks,
Michael

The current in the U.S. is 60 cycles per second. A tungsten bulb filament gets hot and glows. It doesn't cool off enough between pulses of electricity to change color or intensity very much. The phosphors in the flourescent tube don't have that continuous glow to the same extent. Shooting at 1/60 second, if your shutter is accurate, should catch the entire cycle but shooting at 1/30 or longer would be better.

Thanks Al, how would one get that under control say shooting basketball with shutter speeds of 400 and up?
