Thank you for your reply. I did indeed disable the base curve because I wanted a rendition as neutral as possible. I certainly mean no offense, but it appears to me that the architecture of darktable is wrong if it cannot produce natural colors with only an input and display profile and no further adjustments. Is this not the point of an input profile in the first place? Why would I need to mess with any curves? This seems really wrong to me, but I would be open to a good explanation.
The reason I want to avoid messing with curves its that it cannot avoid to distort colors, no matter how close to "nothing" the curve is, this should not be required. Please help me understand this. The only thing in favor if your approach right now is that the Rawtherapee rendering is very similar to that off darktable, and yet it still appears wrong to me. I appreciate all the help you can get me.
