5D Discoloration

This is my second post of the day about other photgoraphers issues but here we go anyway. As this photographer was shooting the event, his 5D Classic gave him these random discolorations. These are the only 2 out of the 200+ pictures. Everyother image came out spot on with color. What would cause this? WB is not the answer, it didnt get switched to a different setting, the pictures before and after are perfect color. Metedata on the images show no change in any field between a regularly colored image and these. Any input would be great. Thanks

No idea... subscribing.

Do you have an example of an image where the colors are all in order? (Similar lighting, skin tones, etc. as the two examples). Were these shot in RAW or JPEG?

Looks like white balance color shifts. You can change it in the camera. Dunno if that is what this is though.

Are these is RAW? Is the WB the same for both of these shots in RAW settings?

Wow - this is interesting, as I have two of the old beasts.

Have no idea either, but - I'm wondering... is it possible that the metering on the 5D picked up some random, extremely different WB reflection from somebody else's flash and tried to " WB " that? I know that's a big stretch.....

Yeah I was wondering if some split second lighting anomaly might have influenced the auto WB.

Could the card be bad? I know most car failures look a little more like artifacts in the image but who knows.

You say every other image but all the bad ones either Green or Blue ? Even though you have red robes in the shots, Do any of the shots have a red cast? Maybe the sensor is going bad.

Hmmmm - hard to say. I always felt that bad or "dying" cards resulted in strange banding, wierd pixilation or other distorted displays. These are clear, sharp images, just badly WB'd. Maybe things were shot pretty fast in sequence and something hickupped in the 5D's buffer.

What happens if you use the ACR white balance dropper to try to correct it? This looks more like a tint than a WB problem though. I'd like to see a good raw and a bad raw side by side, if you want to email them to me that'd be interesting.

All images were shot in JPEG. I couldn't confirm the white balance by the metadata though. I always thought the metadata would show flash if you shot flash but all these images (including the good color ones) say "manual".

In answer to whether any images have a red tone....
None of them do. They are all purple and green as far as I know.

In response to whether there was a strange light such as another flash discharging at this moment....
This happened on at least one other shoot. Not to rule out that explanation but that is a rare and hard thing to do. Ill propose this to the photographer and see what he thinks. He was there after all.

I thought about the WB dropper as well. It helped to a certain extent but the image is still unrecoverable. If you can try on such a small image go for it (the students collar is supposed to be white). Otherwise, pm me your email and I will send the bad image and a good image to you.

Thank you for all the responses. All input is certainly appreciated.
