I'm editing a back-lighted portrait. Sky backwards it's mostly overexposed, but some information was preserved on the upper left corner of the frame. I shooted on both JPG and RAW (canon's CR2)
This is the unedited jpg version (detail)
This is the CR2 I'm working on (detail)
I'm changing the upper section of base tonal curve, not being able to achieve the smoothness of unedited jpg.
My goal is to get a blue to white smooth gradient.
I'm working on Darktable 2.0.6, Linux Ubuntu Studio 19.04, and the frame was shot on Canon 80D - Sigma ART 18-35mm 1.8f
