Hi guys.
I'm a Linux user, too. I have used Darktable for 2 years now as my main (and almost only) raw developer for Canon, and now for Fuji.
Yes, the learning curve is steep, but I love this software. It's rich of functions and complete, richer than Lightroom.
I still don't like some modules, such as highlights and shadows (not working well in my opinion, halos are so heavy!), and I think that noise removal is worse compared to competitors. Sometimes it hangs while using masks.
Indeed, I love the equalizer, curves, colors, defringe, and the use of parametric masks.
It's a pity we don't have chromatic aberration correction for Xtrans, yet (would be useful with my samyang 12mm f2)...
What kind of demosaicing method do you use? Markesteijn 3 for me, seems to be better than others.
I have not tried Lightroom (neither 5 nor 6) with FUJI RAFs, since my lightroom trial has expired.
How does it compare to Darktable, based on your experience?
Stefano
