Altering the AWB settings won't affect gain or exposure time. Your code does say you are setting ISO and shutter speed, so it should be fixed.namorK wrote:we're struggling with a pink colour cast and brighter corners due to a lens change. also, we cant't get the exposure set completely manual (camera.awb_mode = 'off', camera.awb_gains = (1.5, 1.5)).
No, there wasn't, and that probably won't help anyway as the response of your lens is unlikely to be totally uniform.namorK wrote:do you know if there was an update to get rid of the lens compensation?
Up to you. They should both expose the same functionality.namorK wrote:and what would you suggest, would it be easier to use raspivideo and a shell script?
Correct. Stats pass does NOT affect video capture, only stills. When the raw frame has been captured, it is passed through the ISP to produce statistics alone, recomputes gains based on those stats, and then processes the data again to produce the output frame. It's mainly used with a flash, as that can vary all the parameters quite significantly.namorK wrote:did i get it right? using the statistics pass doesn't affect video capture. or would there be a possibility to program a white balance feature and use it before we let our balloon fly?

Sadly I can't release the source for it. It is baked into our video processing software, and that is proprietary.
But if your problem is that you have a single camera that has a color issue, then I suggest you search around the forum here for other threads. My issue in this thread is a very very subtle difference in colors between multiple cameras that is only noticeable when stitching together the images from several cameras. I know I have seen reported issues with single camera color gradient problems in other threads.
