@martijnbraam Some time ago, I used #darktable to remove the green hue from the #GC2145 (#pinephone front camera) pictures, like so: color calibration
Red: input red 1.0 input green 0 input blue 0
Green: input red 0 input green 0.8 input blue 0.2
Blue: input red 0 input green 0.2 input blue 1.2
Never figured out how to convert that to a #megapixels #colormatrix...
Any tips?
@zachdecook That's not that simple since those values are dependent on the lighting conditions, the image is so green because the auto whitebalance does not run. I think it's a better fix to have a manual whitebalance control in megapixels
