These can be optimised using the methods in the camera tuning tool shipped with libcamera. Though most of the camera tuning tool methods make assumptions that are invalid for a microscope. As such any tuning would further consideration.

### rpi.geq - Green Equalisation
#### The problems with green equalisation
This tried to calculate whether adjacent grren pixels should be equal. This interacts very porly with the chief ray angle compesation when using the camera. The imx219 has a lenslet array:
