I finally got access to the latest version of Lightroom, where I played around with dehaze on @David_LaCivita’s picture.
The effect seems to suffer from the haloing that @CarVac described:
Original
LR dehaze +50
LR dehaze +100
For comparison, here is what I achieved using darktable’s equalizer module blended with a parametric mask:
And here is a side-by-side comparison of the Lightroom, darktable, and @Carmelo_DrRaw’s edit in PhotoFlow:
General thoughts:
Dehaze +100 is an extreme case that leads to haloing, however Dehaze seems to preserve the original colours better.
darktable and PhotoFlow recover some details but seem to lose a lot of the richness of the colours.
