Re: [darktable-user] "while balance applied twice" warning in DT 4.0
Now I get the same problem when importing a new photo in 4.0. It's fine right after import, but as soon as I change something in the White Balance module, I get the "while balance applied twice" warning, and in Color Calibration it says "white balance module error". I get this in the console: - [color calibration] white balance error [color calibration] white balance error [color calibration] white balance error [white balance] double application of white balance [white balance] double application of white balance [color calibration] white balance error - Changing something in the Color Calibration module seems to work normally and doesn't give me any warning.

My Camera is Sony RX-100 M5A, which was supported in 3.8 also. (Also using Ubuntu 20.04.) What's going on?

I will have to learn some more things, as it comes with many improvements and bug fixes. And it finally brings wb and noiseprofile support for my D4s. About wb, I noticed something strange. I had worked on a few photos on 3.8, on which I had set wb to Camera neutral and adjusted Color calibration using the color picker. But, when I reviewed my photos on 4.0, a few minutes ago, they all displayed a warning on both wb and cc, and it appeared that wb was reset to Camera (instead of Camera neutral). Could this be a normal behaviour, due to the fact that there were no wb support for this camera before ?

The reasoning behind that is that the demosaic module needs some form of white balancing/camera correction to give a decent result, but the proper place to correct for illuminant (aka colour of scene lighting) is later in the pipeline. For more precise information, you may want to check Aurelien Pierre's posts and articles (on pixls.us iirc). So, either leave WB module in "camera reference", correct white balance in color calibration module, or don't use the color calibration module for setting the white balance. You can set the adaptation to "none (bypass)" if you want to use the other possibilities of this module.

Re: [darktable-user] "while balance applied twice" warning in DT 4.0
Ah, got it, thanks for the explanation. Now when I know how it works, it makes sense. (I guess that I should have read the user manual before asking, since it is explained there.) However, I think the error messages could be improved. I am used to modules working more or less independently from each other, and this coupling is unexpected.

I'm having a hard time finding stuff on pixls.us. Can you give some pointers?

I must admit I did not understand when I read this using the help on the WB module. But now, after Pascal explained it and you pointed it again, I read the help again and finally found that it makes sense. [OT]By the way, I realize that I never thanked the devs for adding exif handling in the metadata fields at import. This feature is really helpful. Many thanks. :-) [/OT] Rgrds, J.-Luc darktable user mailing list to unsubscribe send a mail to darktable-user+unsubscr...@lists.darktable.org
