I have Lightroom 6 and when I look up the topic "reduce haze in a photo" a fairly simple answer comes up. You just go to the develop module and choose the effects section. At the bottom of the section is a dehaze tool except I have no such slider. I only have the Post Crop Vignetting tool and the Grain tool but not a dehazing tool. I read the the dehaze tool was added in Lightroom 4.1 and higher but I don't have it. Any suggestions??
Dehaze was added in CC2015.1 - not in LR6.1.
Only the CC version do get new features while the standalone version get bugfixes and new profiles.
Only introduced for Creative Cloud subscribers when version 6.1 was released.
Dehaze- This feature is available only in Lightroom CC 2015.1. (and later CC versions)
Stand-Alone versions will need to wait for v7.
