Thanks for the samples and further info!
It’s a surprisingly complex subject.
Those the basic modules that dt applies to get your image to a workable state.
- color calibration - this is for white balancing (plus more, but this is the base purpose)
- exposure - this is basically brightness adjustment
- filmic rgb - this is a sophisticated version of a tone curve
These defaults are set in the preferences, like so:
I prefer the sigmoid option instead of filmic, as I find it gives a more familiar starting point. Note if you change this, it will only affect images you haven not edited before, unless you discard the history for that image.
I’ve had a try at your image,this is what I was able to get after a little fiddling (ok, 15 min…)

I’ve also created a style, that can be applied easily to any photo. I don’t know how close it will be on other shots - a sample of one isn’t that reliable
