Yes, but the hard part is knowing how to use the raw-black points module.
Rawpedia says nothing about haze: http://rawpedia.rawtherapee.com/Raw_Black_Points
But it seems to work very well in conjunction with the haze removal module.
But … How do you get those 239-530-477 values in this image?
The same here:
Where do the values 57-224-219 come from?
Do you have to calculate it by eye?
It must be a very well kept secret :))
Regards!
