For me, the dehaze tool is awesome (when used appropriately). I think that you could do the same using a combination of other sliders but the way it slices through mist/clouds is great. For underwater shots, I use it with almost every shot.Interesting.
Can you point to some of the earth shaking, can't do without improvements Adobe has done to say, Photoshop....that makes it so superior to CS6 that you can't live without? What amazing functionality have they added since then that blows CS6 out of the water and gives functionality you cannot do before rental model?
Just curious, maybe I missed it, I do try to keep up and listen for the updates, but I"ve yet to see anything so mind blowing for PS or LR that I couldn't still do inCS6 and LR5 for the most part...
