I quite often experience a brownish color cast when shooting indoors, although it isn't always there. The following clip (20 seconds long) illustrates the situation (http://vimeo.com/7128305). The clip is made up of two scenes that were shot separately. The first half of the clip has normal lighting, but the second half has the described color cast. The two shots were made just minutes apart. Power on the camera may have been switched off and on again in between. Also, I don't remember what the camera settings were in this case, but I'm sure they were the same.

Is anyone else experiencing this? Any ideas/suggestions would be greatly appreciated!

Thanks,
Sigr
