Do any of them support HDR colorspaces?

That’s my big sore point. I need something more like Darkroom/Darktable than a full blown editor, but basically nothing supports HDR well.

Darktable can technically output HDR files from RAW, but can’t render it! I have no idea what it’ll look like when editing. Last I tried, GIMP doesn’t support it at all, and almost nothing on Earth will output a gainmapped file. But Adobe software is one of the few that, unfortunately, gets most of it right…
