Here's a question for anyone who has done timelapse photography with the Canon 5D. I have done several series with the white balance set to sunny. When creating a movie (using After Effects), I have seen flickering. So it seems to me that either the camera's shutter speed is not consistent, or that the white balance is not actually locked.

I have not yet seen this with timelapse sequences under different lighting conditions (for example, cloudy and night), but it's possible that under lower light, the problem is not as noticeable.

I have also not tested by creating a closely controlled sequence (say, under artificial lighting) or by setting the white balance manually.

Thanks.

I assume u are using raw files? If I were u I will set the white balance to AWB and fixed it later using raw converter program before after effects to get a uniform whitebalance and exposure.

I recall that DxO Optics Pro v4 has a facility to match colors across several images. Might be worth a look.

I'm just going thru some pics in ACR. They were taken at same exposure indoors and the white balance varies markedly. Now there are windows with some daylight coming in but that wasn't changing much as the exposure is constant. Very odd.
Shots were taken in quick succesion and from same postion yet vary by as much as 400 degrees.
