Have been playing around with the beta version of Photoshop CS6 and I’m impressed. I love the new, darker, interface, and the images are quicker to load and seem sharper (my imagination?). Not sure that I’ll have that much use for content aware move in wildlife photography, but you never know.
Camera Raw 7.0 gives users the ability to alter shadows and highlights from CR, rather than opening in Photoshop and fiddling from there.
All in all it’s going to be fun to play around with it, and there are lots of short videos on Lynda.com to explain the new features.
