Could it be that ART 1.25.8 suddenly displays values for a and b that are much too low with the color picker?
I can’t verify it technically, but a and b should be around 20 for this skin tone.
At least that was the case until recently.
RawTherapee displays the following:
(Both screenshots were taken from a JPEG generated with ART.)
Could not reproduce with a quick check on a few samples of similar skin tones. a/b around 20. ART built from latest sources on Fedora 42.
To my great surprise, older ART versions (1.23, 1.25.0, and 1.25.1) also show roughly the same values, each about 10 lower than expected. Now I suspect that it might have something to do with the settings in ART, which I may have accidentally changed. However, I see that the values in Working Profile do not fluctuate by more than ±1, so that alone cannot be the cause.
Is there a setting in ART that could influence this?
My system is Manjaro Linux.
I found the operating error: I had clicked here: working profile. When I turn it off again, everything is back to normal.
It was my mistake, not a bug.
What surprises me is that the colors displayed are the same, only the L a b values in the color picker differ significantly.
