ACES and ACEScg support
I wanted to ask if would it be possible to add ACES and ACEScg support as a output color profile when working with RAW photos:
It is already implemented in dcraw, but to have it also in darktable would be a big plus :)
Thank you very much for consideration and have a nice day

What exactly are you asking for? Just ACES as the export profile? That's already possible, just copy a matching ICC to ~/.config/darktable/color/out/. Or do you want to export to half float EXR? Or do you want to have darktable to work according to the ACES standard in its internal pipe?

Tobias thank you very much for your reply.
Well darktable working in ACES standards (or in OCIO) in its internal pipe would be great, but I know that it is a huge request so I posted it as a second feature idea, separate from this one. For now it would be great to have at least this ACES export as a first step :) But its a great new that it is possible to do it this way, I did not know about this option before, thank you very much :) I thought that export is only limited to sRGB, AdobeRGB, linear Rec709, linear Rec2020 and BRG (These are the only options I see in drop-down menus). Maybe there could be some GUI element which would allow users to add their own icc? I read the documentation few months ago but I thought that ICC color profiles in this directory would be only usable as input color profiles. Half-float EXRs would be great but are not critically needed - I think that 16/32bit TIFFs can provide the same output quality, or not?

- Status changed from New to Closed: invalid
https://www.darktable.org/usermanual/en/color_group.html#output_color_profile tells about the possible output color profile locations, the same is also shown in the tooltip when hovering the dropdown. I don't think that adding new color profiles is a task common enough to justify its own GUI.
About export file formats, you can surely use TIFF, or full float OpenEXR.

Thank you very much Tobias, you are right it is pretty clearly stated. To be honest I consider myself experienced darktable user (I use it since version 1.4+) and I never noticed that tooltip before, even thought I wondered about if it is possible to export to different color spaces. I understand that maybe it is too much to add a button for it, but maybe make it somehow more intuitive or make this information more "visible'? I'm not sure, I don't want to persuade you now, just want to share my experience that eventhough I used darktable a lot I never noticed it. In my UI/UX experience, if I use some tool and there is only a drop-down menu and no "GUI element" where I can load some custom file, I think of this tool as-is, I usually don't even think that there could be some possibility of expanding it. But this is just my opinion or advice, not a objective truth :) Anyway thank you very much for your help and have a nice day
