Hi Johannes, I only pushed a few stops to exaggerate it. I'm seeing green shadows even in well lit daylight ISO 1600 shots without exposure compensation, but i felt this image could demonstrate it much better. Also, in your screenshot the shadows are still green, just less obvious because they are darker. They are not green in Adobe Camera Raw, DxO and Aperture and they aren't in RawTherapee either, all at default settings, white balance as shot, exposure compensation set at any value, camera profile set to any profile. I added a Camera Raw sample to the Dropbox folder as an additional sample. If it's just a limitation of the way Darktable processes these images, so be it, but to me it seems very much like the issue RawTherapee had in 2013. Sadly I do not have a sample of the old RawTherapee picture anymore. I'll check if I can download an older version. It was just as bad as it is in Darktable now. There is another (closed source) raw editor with this issue, but I don't remember which one it was.
Also, I'll try to set the blackpoint myself. I didn't realize there is a gui option for that. I'll report back. Hopefully it's indeed consistent across images, although I could not find the correct blackpoint in the gui of RawTherapee before they patched DCRaw.
