Features:

New Adjustments and Masks panels
Easily access every tool for nondestructive adjustment of color and tone. Quickly adjust specific image areas with easier access to all the tools for creating and editing nondestructive masks.

Nondestructive image editing
Experiment without harming your original photo. Visualize different effects and manipulate objects using nondestructive Smart Filters and Smart Objects. Preserve color and tone details as you correct with intelligent Dodge, Burn, and Sponge tools.

Better raw image processing
Enjoy superior conversion quality as you process raw images with the industry-leading Adobe Photoshop Camera Raw 5 plug-in, which now offers localized corrections, post-crop vignetting, TIFF and JPEG processing, and support for more than 190 camera models.

Quick Selection tool
Loosely draw on an image area and the Quick Selection tool automatically completes the selection for you. Then use simple sliders to preview and refine your selection.

Improved Adobe Photoshop Lightroom workflow
Select multiple photos in Adobe Photoshop Lightroom® software (sold separately) and automatically open them in Photoshop CS4 to merge them into a panorama, a high dynamic range (HDR) photo, or a multilayered Photoshop document. And seamlessly roundtrip back to Lightroom.

Extended depth of field
Easily create a single image from a series of shots that have different focal points with the enhanced Auto-Blend Layers command, which smoothly blends color and shading and now extends your depth of field, automatically correcting vignettes and lens distortion.

Auto-alignment of layers
Create accurate composites with the enhanced Auto-Align Layers command. Move, rotate, or warp layers to align them more accurately than ever before. Or use spherical alignment to create breathtaking panoramas.

Auto-blending of images
Combine a range of images, each with a different exposure, color, and focal point — with options to preserve tones and colors — into a single color-corrected image.

More powerful printing options
Get outstanding prints with superior color management, tighter integration with leading printer models, and the ability to preview out-of-gamut image areas. Support for 16-bit printing on Mac OS offers increased color depth and clarity.
