Hi Francisco,
Ulrich's advice seems right on!
In the newer NEF file I'm still not seeing areas of reds with low enough
luminosity to trigger these artifacts. It may just be that the X-Trans
image by a particularly fortuitous chance recorded such saturated dark
reds, but that's a hard to replicate

Hi Francisco,
This is interesting... The trouble seems to come via the tone curve
module's automatic scale chroma setting. (The noise doesn't seem to
depend upon the demosaicing algorithm -- it's there with VNG or
Markesteijn.)
When "scale chroma" is set, each pixel processed has its saturation
Hi Mark,
There is indeed a branch with X-Trans support:
https://github.com/dtorop/darktable/tree/xtrans2. If you're comfortable
with Github and compiling your own code, do try it out. You should have
good results, but any feedback is most welcome.
See http://www.darktable.org/redmine/issues/9951
Hi David,
That's great to hear! I do think the non-magenta highlights are thanks
to the camera tonal range and the default Fuji basecurve compressing
highlights. I'm curious if this cameras produces unusually good
highlights?
In general the x-trans branch should be getting somewhere stable, thoug
