Weird D3 Color Cast

->> So getting back into shooting some college stuff around here, and I've started noticing a weird color cast on my D3 files. It only happens when I'm shooting in lowlight (Usually around 2500-3200) and in high rapid fire mode.
Oddly, I'm seeing it on both of my D3 bodies. Every other frame has a weird color hue halfway through the image. Almost looks like when your flash is out of sync a smidge and you catch part of the shutter.
- Shooting RAW
- Tried different metering modes and worked with custom white balance to see if that helped. No dice. Only happens during night games and low light, and the shutter only has about 150K actuations.
Anyone else experienced anything like this? |

| ->> Sounds like the lights are cycling. I see it a lot when shooting HS events outdoors but especially indoors. There really is no real way to stop it from occurring unless you like shooting at 1/30th or 1/60th, as you shouldn't catch it then. Or you could just talk to the school and have them put in more lights! |

->> It's almost certainly what Geoffrey said. Lights at most venues are not continuous - they are gas discharge lamps that flicker, usually around 60 times a second. When the discharge happens each 60th of a second, it doesn't happen instantaneously...the light gets brighter then fades. During the fade, the color temperature shifts. If you are shooting at a fast shutter speed, you'll catch this fade.
You can test this theory by shooting something white with a manual white balance while varying your shutter speed. At speeds below 1/60th the color should be pretty consistent. As you get faster than this you should start seeing the color go weird.
No way to fix it on your end other than using strobe or shooting at a slower shutter speed... |

| ->> Thanks for clarifying! Don't know why I didn't think of that, but it makes perfect sense. Especially since there was no real pattern to the color shifts. |

| ->> you will get that a lot in high school gyms if you don't already light the place yourself. |
