What's new in Adobe Lightroom CC (pictures)
Adobe's overhauled the import interface, added a dehaze to the adjustment brush and streamlined the import of Photoshop Elements catalogs.

New import interface
Every time you add photos, you have to go through this screen. It's less intimidating and more touch-friendly than the previous interface, but I prefer not having to go through the extra screen.
Overboard?
The new import interface puts a large overlay on all the thumbnails -- once again, more touch-friendly. I thought this meant these images had already been imported, but no -- these are the new ones. I'm not fond of this interface.
Tool search
Can't find what you're looking for? You can now search for tools, and it will even show you where they are. Unfortunately, here I was trying to find out what Auto Sync was (and if it was different than the existing Auto Sync). No luck.
Local dehaze
By painting on the mask with the adjustment brush, I was able to bring out the scenery in the background (original on left, retouched on right).
Local vs. global dehaze
Local dehaze, which appears as a slider under the adjustment brush, is a really welcome feature. On the left you can see the effect of the global dehaze, versus applying it just to the mountains in the background (right).
Braving the Elements
Lightroom now has a one-click interface for importing Photoshop Elements catalogs. It didn't seem to bring in all my recognized faces, though it kept the names as tags on the photos. In order for you to get the faces in, you have to start face recognition for the entire catalog; then it takes the tagged faces and adds them.
