Darktable 5.4 is out with a new AgX tone compression module. I love the provided camera styles, because I mostly do documentary photography, where you aren't supposed to do much editing other than fixing exposure, white balance etc when needed.

The current camera styles are for filmic module, so I spent a bit of time creating an AGX one is close to standard out of camera standard picture profile.

So here's the darktable camera style with AGX for the Sony A6700.
