Hi.
Depends on your assigned profile.
First Solution: assign any profile you want (doesn’t matter), change the values of haze removel tool as you like, save profile file (.pp3) to your “profiles” directory (default: “C:/Users/Username/AppData/Local/RawTherapee/profiles” in Windows10), load or assign this profile to other photos as you want…
Second solution: open such a profile (.pp3) file in a text editor, search for “haze removal”, change values, save and close .pp3 file.
Third solution:
