Looks amazing and I can't wait for the full version to come out!
1. New Interface Photoshop CS6 comes with a new darkened user interface. It's less cluttered and more streamlined. Some might prefer the new look and others might reject it, but it is more contemporary. And because you can control how dark the UI appears and can choose between four different UI color schemes, there's probably a setting that will suit everyone.
2. Adobe Camera Raw 7.0 Raw image files contain the unaltered data captured by digital cameras, before the processing that turns them into viewable images. Photoshop CS6 adds support for Adobe Camera Raw 7.0, a plug-in for editing raw image files. The settings panel has been redone, making it easier to control settings such as Highlights and Shadows.
3 Content-Aware Move. Ever wanted to remove someone from a photo? That's what the Content Aware Fill tool, introduced in Photoshop CS5, can do. In CS6, we have a variation on that theme: Content-Aware Move, which lets you select an object in a single-layer image and move it somewhere else in the picture. Photoshop will fill in the gap created by moving the object, and does so pretty well.
4. Type Styles Dealing with large blocks of text in Photoshop is a pain, or at least it was. Photoshop CS6 is starting to have some of the type styling flexibility of InDesign. New character and paragraph styles make type formatting much easier.
5. Blur Gallery Tilt-shift is the new HDR. The tilt-shift effect--which emphasizes a small in-focus area and blurs the surrounding area to make objects and people look like miniatures--can be accomplished using previous versions of Photoshop, but CS6 makes it even easier with a Blur Gallery that includes Tilt-Shift, Iris, and Field Blur tools.
6. Adaptive Wide Angle This lens correction filter gives you the ability to control the areas in your image that will be subject to adjustment. All you have to do is draw along a curved line of distortion and you can straighten it, making the image look as if it was taken with a different lens.
7. New Crop Tool It's non-destructive, making it easier to play around with cropping variations.
