Or maybe I don’t know how HDRMerge works really… When I open the DNG, it looks exactly like the darkest frame, but when I push the DNG by +4EV I get the same low noise in the shadows as the brightest frame, while pushing the darkest frame by +4EV brings out a lot of noise.
So, I guess it works, and that all I need to push the shadows in the merged DNG?
