@dos Having written that, I absolutely don’t understand most of the stuff Darktable does myself… but I know that much that looking at the “default unedited” photo out of it just makes no sense.
And I believe (though maybe wrongly, being just as, if not much more, ignorant of the other software as the author is about DT) that the other programs presented do a bit more magic with exposure and tone curve adjustments out of the box.
@silmeth Aside of white balance and color calibration, darktable may also apply exposure compensation, highlight recovery and filmic curve by default. But yeah, it's just a very basic processing, "starting point" if you will. It's clear from the photos that other applications did more with it.
@dos True (though again, all of those steps optional, possible to turn off – though I don’t expect the author to have done it), and the default exposure compensation is AFAIK also just flat constant +0.7 stop compensation (clearly visible in the exposure module), and not automatic right exposure level guessing (which again, I’ve a feeling some of those other programs might do – but 🤷).
@silmeth It's 0.7 plus whatever the metadata defines (which is often 0, but still). Nothing "automatic" indeed.
@dos Well, what it does by default also really depends on your settings (it’ll set initial white balance before demozaicking, but will it then read scene data from EXIF and set default color calibration after demozaic? depends, and you can turn it off), and it’s also not clear to me what “defaults” the author used. :P
