I just bought a GL2 and it came in the mail the other day.. Well I started capturing footage in low lighting and it seems like the red balance on it increases.. Why does it do this? Is there anyway to fix this problem?

Low light often means dim incandescent lights, which tend to the red; i.e., low color temperature.

White balance in the camcorder is accomplished by adjusting the gain in the analog amplifiers between the CCD and the A/D converters. They also provide the gain for the gain setting. (Now recall that with film, it takes perhaps 1-2 stops of aperture to compensate for filters beteen daylight and tungston for film.)

Assuming you already have the camcorder gain at max, in poor light you may just plain run out of enough gain to do effective color balance.

The fix is to add more light, go to a slower shutter if you can deal with the motion artifacts, or try do some additional color correction in post - or convince the client it is a new art look..
