@ggc Do you want the colours to be true? Or do you “just” want to put more dynamics into your .DNGs? Do you like the phone’s .JPG images?
If dynamics, make this small experiment with your tree image (as per link above), using RawTherapee:
Load image.
Select Processing profile Neutral.
Second Tab (Detail): set Haze removal to ON, and set Contrast by Detail Levels to ON. In the Contrast by Detail Levels module, click the Contrast+ button four or five times.
Is the image now more to your liking?
If so, start experimenting with Film Simulations, for instance… More info here Film Simulation - RawPedia
Have fun!
