(Darktable tutorials recommend starting with exposure compensation. Is this standard?)

The scene-referred workflow is centered around nailing middle gray. filmic keeps middle gray constant. So, it makes sense to adjust exposure quite early. So is white balance, as it is a fulcrum of color grading in the color balance module.

And therein lies the whole problem of that approach - it is completely counter intuitive to settle on a color grading unless you are color grading video where each frame must match the settled look.

In photography the frames can be widely differently exposed to begin with, even when I am shooting several aspects of the same subject it's often the lighting that is intentionally different and thus having to settle on a color grading makes no sense whatsoever for me, and neither does fixing middle gray - those only get into the way of editing to match the intent of the differences in lighting I settled on when I took the shots because their intent is screwed up in trying to equalize on the captured dynamic range when in fact it's the visual intent that must be  front, middle and center of the RAW development.

When you get the news that there is someone driving the wrong direction on the motorway you're on and you have the second car coming in your direction then you should begin wondering if it's you who is going the wrong direction. In the case of Darktable name one single established photo development tool that is using the same screwed up pipeline that disregards the visual intent of the photographer and imposes a color grade - there isn't a single one. Yet also none of the other tools does tie it's output to a specific display during editing as supposed by the misrepresentation of the main developer of Darktable - they all operate on a large color space with well defined transformations to the display. That developer also has largely discredited himself because in all "publications" he provides on his reasoning instead of demonstrating the superiority of his approach he resorts to foul name calling whenever it comes to arguments against the competing software.

The whole scene approach is completely screwed up because editing a photo has fewer constraints than a video has - constraints (straight jacket type) which Darktable now tries hard to enforce. And since the display (what a misnomer that is - it's a visual referenced workflow unless the tool is a total screwup to begin with) referenced tools are already being phased out. Thanks why  I am going to discourage anyone putting in much time into that crap. If I didn't have a full time employment I would possibly fork before the wavelet mess (which is years before the main developer lost his mind and got into color grading  (the sharpening in DT is completely messed up now as well since the deconvolution they try to use now too needs a setting to prevent the worst of artefacts if you have a good lens - which isn't working well)...

If you want a decent Open Source tool the  look at ART or Rawtherapee, Darktable is going into a niche that has nothing to do with photography and is only relevant to videographers.
