Bayer Rendering and White Balance
As Bayer images, which are comprised of a mosaic of Green, Red, and Blue color filters, are transferred,
they can become biased towards one of the color filters, making your image appear green, red, or blue.
You can correct the image using the Image Processing options in GEVPlayer.
