Yes. > But currently darktable does seem to force output to be in the darktable > version of linear gamma Rec709 (which isn't equivalent to GIMP's > internal linear gamma sRGB color space - > https://mail.gnome.org/archives/gimp-developer-list/2016-April/msg00116.html > -, but hopefully this can be changed). Should be fixed, see the other thread. Once you confirmed that the profiles are fine now we will release darktable 2.0.4. > Right now GIMP is an "sRGB only" image editor.

The reason I chose linear sRGB is that 1) we are exporting to EXR as the intermediate file, so we need a linear profile 2) GIMP seems to work best with sRGB images so far, so I used the linear version of that. I agree that it would be nice to have some choice there. Would default export to linear Rec2020 be better? Still hard coded, but a wider gamut. It seems GIMP asks about converting the colors anyway, so for people that want to work in sRGB that's just one click away. Having a way to actually change the profile from darktable on the fly would require some changed to darktable that I don't want to do right now (pending release, breaking things, you know the drill). Eventually I will think about ways to fix that though. > Also, only some GIMP operations are "sRGB only".
