Adobe’s updated Lightroom CC gave subscribers access to a new Dehaze slider, but this feature has not been made available to user that purchased Lightroom 6. Petapixel has posted an article about a free preset from Prolost that give results very similar to those of the Dehaze slider in the purchased version. The designer of the preset states that the back-end functionality of the feature is available in version 6 but has not been made accessible to users. The preset actually accesses this functionality.
