"localrgb" contains "locallab_dev".
When you open "Local editor", you have 2 expander : 1) local lab; 2) local rgb
For local rgb - only with one spot, for testing algorithms
3) white balance
For WB, I have installed several new "auto wb" - I have found on Web (university...no code furnished, only principle: iterative, edge, etc.) , with some supplementary settings (gamma, cat02..)
The goal is to test
a) in "local mode". I don't think it is very usefull, but to test
b) in full image: put the spot in the center, and area to limit of preview, and transition to maxi....
After that: 1) none is good....2) some AutoWB are good to be placed in "General WB"
