  New Features:

• Smoother panning and zooming and fluid canvas rotation
  Navigate to any area of an image with new, ultra-smooth zooming and panning. Maintain clarity as you zoom to individual pixels and easily edit at the highest magnification with the new Pixel Grid. And use the revolutionary new Rotate View tool to smoothly turn your canvas for distortion-free viewing at any angle.


• Content-Aware Scaling
  Use the new and revolutionary Content-Aware Scaling feature to automatically recompose an image as you resize it, smartly preserving vital areas as the image adapts to the new dimensions. Get the perfect image in one step without time-intensive cropping and retouching.


• Re-editable, feathered, density-controlled masks
  The new Masks panel smooths and speeds the creation and adjustment of pixel and vector masks, making it easier than ever to apply effects to precisely defined areas of an image. Now, with simple sliders, you can adjust the density and feathering of a mask, to control both the sharpness of the mask edge and how much of the adjustment effect you'd like to reveal. The Refine Mask feature allows simple yet fine-grained control over the mask size and edges.


• Extended depth of field
  Whether it's the extreme close-up, the microbial world, or simply low-light conditions, there are times when the depth of field you can capture with your camera is extremely shallow. Now, you can shoot the scene with a series of focal points, and use the enhanced Auto-Blend Layers feature to automatically create a new, single image with a depth of field encompassing the entire series. You can even color-correct the images at the same time, automatically. This feature provides breathtaking enhancement of any scene where lighting and depth of field are in short supply.


• Industry-leading color correction
  Enjoy dramatically enhanced color correction with reengineered Dodge, Burn, and Sponge tools that now intelligently preserve color and tone details.


• File display options
  Easily work with multiple open files by using tabbed document display or n-up views.
