Revolutionary 3D painting and compositing
Now paint directly on 3D models, wrap 2D images around 3D shapes, convert gradient maps to 3D objects, add depth to layers and text, get print-quality output with the new ray-tracing rendering engine, and enjoy exporting to supported common 3D formats.

Adjustments panel
Simplify image adjustment by easily accessing every tool you need to nondestructively adjust and enhance the color and tone of your images; on-image controls and a wide variety of presets are also included in the new live and dynamic Adjustments panel.

3D object and property editing
Edit, enhance, and manipulate 3D images in a streamlined interface without dialog boxes. Adjust lighting, meshes, and materials. Easily orient objects and position the camera using 3D axes and a ground plane.

Masks panel
Quickly create and edit masks from the new Masks panel. This panel offers all the tools you need to create editable pixel- and vector-based masks, adjust mask density and feathering, easily select noncontiguous objects, and more.

Fluid canvas rotation
Now just click to smoothly turn your canvas for distortion-free viewing at any desired angle‚ no more tilting your head in the middle of painting and drawing.

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.

Smoother panning and zooming
Gracefully 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.

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.

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.

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.

Enhanced motion graphics editing
Edit motion graphics more efficiently with new single-key shortcuts, sync visual effects with specific points in an audio track using new audio syncing controls, and turn any 3D object into a video display zone.

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.

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.

Integration with other Adobe software
Be productive with enhanced integration between Photoshop Extended and other Adobe applications you depend on, including Adobe After Effects‚®, Adobe Premiere‚® Pro, and Adobe Flash Professional software.

Industry-leading color correction

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

Improved Adobe Photoshop Lightroom workflow
Select multiple photos in Adobe Photoshop Lightroom,® (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.

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

Extensibility
Get and share Adobe Flash technology-based panels that developers create to accomplish customized tasks. Plus, get tips and tricks from the thriving worldwide community of Photoshop users through the new Adobe Community Help online service.

Adobe Photoshop CS4 software takes advantage of the latest graphics processing unit (GPU) hardware to deliver superior performance. The software offers a smooth pan and zoom experience that allows users to easily edit images at the highest magnification while maintaining clarity.

The new Canvas Rotation tool makes it simple to rotate and work on an image from any angle. Photoshop CS4 helps keep work areas clutter-free with a new unified application frame, tab-based interface and self-adjusting panels that make it easy to quickly access advanced tools, and provide a more fluid way to interact with the application.

Adobe CS4 Extended includes all the new features of Photoshop CS4 plus the ability to manipulate 3D imagery easier than ever before. Now, creativity knows no bounds, as users can paint directly on 3D models and surfaces, merge 2-D files onto 3D images and animate 3D objects. The 3D engine has been rebuilt from the ground up to provide faster performance, allow editing of properties like light and the ability to create more realistic renderings with a new high-quality ray-tracer. Video professionals have the ability to turn any 3D object into a video display zone and can animate 3D objects and properties with ease. In addition, the core motion graphics editing has been improved with more efficient single-key shortcuts.

Photoshop users may take a while to move to the new 64-bit version of Photoshop CS4, but it's an important development; meanwhile, CS4 offers plenty of other significant upgrades to keep 32-bit users happy.
Photoshop now comes in both 32- and 64-bit Windows Vista versions. The 64-bit edition will allow PCs with lots of RAM to work on very large images with less hard-disk swapping (ideally, no swapping at all), thus speeding up operations. With the shrinking amount of RAM available to modern PCs (due to a 4GB limit on 32-bit Windows versions and those operating systems' increasing hunger for RAM), that's a significant update.
