Hello,
I have been using darktable with various Nikon cameras (mostly D60 and
D5200 and occasionally a couple of shots of other, mostly Nikon,
cameras) and have not observed such color bias so hard to overcome.
What I noticed, however, is that the base curve module changes hues and
increases saturation significantly. Its high increase in medium-light
contrast comes at the cost of loss in shadows and highlights. Depending
on the output medium and audience, I sometimes use presets "similar
Nikon", "alternate similar Nikon", "natural", or even disable the
module. I noticed that disabling the module (and compensating by
increasing the luminosity of the display, which is not an option when
the final output is paper) provides the most natural colors.
Can you post RAW and JPEG files that illustrate the problem ? I'd like
to see what you observed.
Thanks.

Hello list,
recently I have been experimenting with raw NEF files from a Nikon
D750 in Darktable 1.6.
Compared to the camera rendered JPG however, at initial import the
colors seemed significantly off. In particular, the camera JPGs had
fairly natural skin tones even with indoor lighting and auto WB,
whereas the same shots imported as NEF files into Darktable had by
default rather unnatural orange-ish skin colors. Overall WB also
seemed a bit off (somewhat yellow-greenish I would say), even though
WB in Darktable was set to camera WB.
I'm by all means a beginner, so I'm probably doing something wrong,
but toying with WB, saturation, tone curves etc., I found it very hard
to even match the camera JPG color quality, let alone improve on it.
Any suggestions as to what I might be doing wrong?
Thanks a lot
