Last weekend I took some photos in the mountains, where I can't control the light, nor the movement of the subjects.
Some of the photos had very little contrast and brightness, and were a bit underexposed.
I edited the raw images with Darktable, and stretched the histogram using the exposure tool.
This image have got good contrast and brightness, but some defects. Posterization I believe, but not for sure.
What is the "right way" in this case? Not stretching histogram? Not doing it that much? Other Darktable module?
I took the photos on the mountains in cloudy conditions. With some of the subjects moving while I was walking. ISO and shutter speed in auto. So, probably I can do better with more experience and skill, and avoid bad exposure in first place.
