Indeed the first thing I'm doing is applying a style either switching to
the base curve, or disabling the module to use filmic. I love what I can
get out of filmic often, but to be honest Aurélien, filmic is also a bit
complex to use. I'm trying the presets, but often I have to change the
settings manually. I can't say that I understand the effect of each
parameter well enough. I guess it must mean that I don't understand the
theory enough. But Darktable isn't only for experts, maybe a tutorial would
help a bit ? Or maybe I just need to learn all the theory better...

In any case, even with my poor skills, I can get photos out of filmic that
I could never get with the old modules. So it's surely a great improvement
!
