Megapixels tuning

Code:

< model=PinePhone Pro

> model=PinePhone

< blacklevel=16

> blacklevel=3

< #colormatrix=1.384,-0.3203,-0.0124,-0.2728,1.049,0.1556,-0.0506,0.2577,0.8050
< #forwardmatrix=0.7331,0.1294,0.1018,0.3039,0.6698,0.0263,0.0002,0.0556,0.7693
< blacklevel=3
< whitelevel=255

< iso-min=100
< iso-max=64000

I have some tweaks to the configuration file for the megapixels-ppp package. It is important to increase the blacklevel settings as seen above. The old values for the two cameras  of 3 and 0 need to increase to the two new values of 16 and 3. The old values washed out the blacks. This even prevents a good color calibration for raw dng post processing.

The file to be copied and modified is pine64,pinephone-pro.ini in the directory /usr/share/megapixels/config/ . I would put a copy in the ~/.config/megapixels/config/ directory and then edit the file to insert the new blacklevel values at least.
