Hey guys,
I just encountered a problem similar to the known "color shifting" issue with the GH1. I mounted the camera on the hood of my car and shot a close-up of the driver through the windshield.
The problem is that, intermittently, the saturation of the colors "pops" from less saturated to more saturated and back again.
I used a Canon 50mm FD lens, Creative Movie Mode, everything full manual. No "intelligent" or "auto" settings were engaged. AVCHD 720p60. Smooth setting, NR at 0, Contrast at -1, Sharpness at -2. Shutter at 1/50 or 1/60. Used a polarizer on the lens to cut the reflections. I don't think the polarizer is the culprit as the change in saturation literally pops to a different setting in one frame's time.
Sorry I don't have any footage to show to illustrate the problem. I can post some tonight.
My hunch is that the vibration of the vehicle may have something to do with it. Either that or the changing reflections on the windshield glass makes the camera do something similar to the "color shifting" problem.
On a related note, if you want to shoot though the windshield of a moving car with the GH1, get ready for plenty of Jello, at least when using anything other than a wide-angle lens. The road needs to be as smooth as glass, or else!
I discovered if you want to get a shot of somebody driving a car while under the influence of drugs, the GH1's Jello effect is perfect! :cheesy:
