Description
When working with raw images (e.g. to generate the lens shading table) I currently rely on the blacklevel being 64. This is only true for the camera module v2, running on a Pi <=4. It would be nice to read the black level from the camera, so this is not hard-coded. That might even allow a high quality camera to be calibrated reliably for LST and colour balance.

Research direction
Start by locating where the blacklevel value of 64 is used when processing raw images for lens shading tables and colour balance. Investigate how the camera exposes its black level across the supported camera modules and Pi versions; done means calibration no longer depends on that hard-coded value.
