I’ll stick to your suggestion for now, and meditate on the other settings and the documentation for now. It seems right.
Actually I just realized that if I pick Bundled Profiles / Default (which uses “auto-matched camera profile”, working profile ProPhoto and output profile RT_sRGB) and then disables the “Base table” checkbox, I get really nice results. So maybe the “Base table” thingie is what I don’t like. (Will read up on this now… )
The reason I’m experimenting this much with my Nikon D600 images is, that I’ve never reached a point where I get the same fantastic color reproduction as the Fuji S2/S3/S5 Pro series that I used to work with. These cameras even gave perfect colors when using out-of-camera jpeg, which I find pretty surprising considering what camera jpeg files usually look like for most other cameras.
I have a gut feeling that Nikon (using a Sony sensor btw) are sacrificing color precision a bit to get lower noise levels at high ISO values, which is where D600 beats the Fuji S5 any day. On a sunny day I’d prefer the S5 Pro, but at night the D600 wins.
I’m just happy that RawTherapee lets me tweak so many settings. It’s quite educational.
