Hi, that's the problem I got with filmic. Once the wall of the non-linearity is crossed, there is no coming back, so all you can do is move your module to the right place in the pipe. Basically every filter dealing with physical phenomenons (diffusion, refraction) should be put in the linear part

I always assumed that basecurve fucks up the whole linear workflow. So I always have it off. But still, what then? I mean each module that relies on a certain color space must take into consideration everything in the pipe before (and possible undo it, which is not always really possible) to p

Hi, quick question: what do RBG color values actually represent in darktable just after basecurve module? For simplicity, let us assume "input color profile" is standard color matrix with Rect2020-RGB as working profile (In case that this is of any relevance.). Backgroud of my question: The
