Yes, it's look neutral. But this pic is overexposed!
And... if I move exposition to down — UPS :-(
I hate magenta on the sky :-(

Yes, It works! Thanks! White sky better then pink sky! But... why in Adobe
Lightroom I see gradients and middle colors between white & blue? And I see
in the darktable sloppy spots with clear contrasting borders :-(

Yes, I use 1.3+1069~g79488d8 (version from Darktable Unstable PPA —

Yes, I use 6D, and sometimes I use 5d3 from my friend, and it has similar
problem. I can show files from 5dIII with overexposures, if it needed.

Yes, I think perhaps this is the case bug. 5dIII and 6d are using 24-bit
color, and the old converters can not even properly display their RAWs. But
the bug is marked as fixed!

Oh, no. I can sometimes use Windows, but I do not like to do it. If we have
to take a laptop with Windows - it is easier to use Lightroom. But I want
to use darktable with Ubuntu.
Many thanks for all! You help me very match!
Also, I want pic from darktable with highlights and overexposures like as
from lightroom ;-)
Best wishes, Liudmila
