I said a few days ago that the basic curve gives lobster skin to people.
I'm now working on a whole batch of landscapes photographies, and for them
too the colors are very wrong, with greens and yellows completely
oversaturated.
In both cases, I have to deactivate the basic curve in order to start
working on a not too bad picture. When doing so, in both cases, the
histogram comes way too much on the left, and I need to adjust the
exposition for every picture... to the point I'm wondering whether the
basic curve could be supposed to fix a wrong exposition treatment when
demosaicing.

At shooting time, I take care of the exposition so the histogram is on the
right side, sometimes blowing up the higlights. I definitely don't
understand why/how I get an underexposed picture when I import it in
Darktable and deactivate the basic curve.
