On win x64 the brightness seem to be changing for different images.

original GK-2A:
animated_org

windows 10 x64:
C:\D\sanchez-v1.0.8-win-x64>Sanchez.exe -s 20201011 -o 20201011_colored
animated

linux raspberrypi 5.4.51
pi@raspberrypi:~ $ sanchez-v1.0.8-linux-arm/Sanchez -s xrit-rx/received/LRIT/20201011 -o xrit-rx/COLORED

Thanks for reporting this, Ivan. This seems to be unique to GK-2A and my suspicion is that it's related to the different temperature of Australia over a 24 hour period, combined with auto level adjustment.

Try with the -L option to not perform automatic level adjustments.

-L works like magic. Thanks!
Btw, is it possible to change the brightness of the haze?

Sure, that's a reasonable request. I'll add it to be backlog. Thanks!
