Photoshop CS4 Extended 11.0, Win, NL
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.
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.
Auto-blending of images
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.
Extended depth of field
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.
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.
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.
