THX for all the answers! I'm still studying and testing (both GIMP and Darktable). I'm working with an "as is" output from DSS, so, yes, it's a stacking of different raw images. The final output is a 32 bit TIF and this is my input in darktable. As far as I can tell it seems that for stretching purpouse photosop works with 32 bit, but when it comes to "curves" I had to convert from 32 to 16 bit in "exposure and gamma" mode.
