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

Discussion in '35mm Cameras' started by Michael Stevens, Sep 22, 2003.

    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.)

  6. 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.

  7. 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

  8. 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.

  11. 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.

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

  13. 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.
