Create powerful images with the professional standard 
Adobe Photoshop - the essential software for perfecting your images, Adobe Photoshop CS4 now offers
productivity and workflow enhancements, powerful new editing tools, and breakthrough compositing
capabilities.
Adobe Photoshop CS4 software accelerates your path from imagination to imagery. Ideal for
photographers, graphic designers, and web designers, the professional standard delivers new
features
such as automatic layer alignment and blending that enable advanced compositing. Live filters boost
the comprehensive, nondestructive editing toolset for increased flexibility. And a streamlined
interface and new timesaving tools make your work flow faster.
Adobe Photoshop CS4 Extended software delivers all the features in Photoshop CS4, plus new features
for working with 3D imagery, motion-based content, and advanced image analysis. If you work in
film,
video, multimedia, 3D, manufacturing, architecture, engineering, medicine, or science, Photoshop
Extended is for you.
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.
