Photoshop CS4's new GPU-aware nature allows it to share intensive tasks with the graphics card, speeding up operations significantly. Photoshop will offload panning, zooming, canvas rotation and several other operations to the GPU, allowing users to also experience a more free-flowing workspace.

In addition to the above-mentioned features, Photoshop CS4 Extended allows users to paint directly on 3D objects, as well as texturing them with 2D images. Users can also animate 3D objects, and the software includes a new ray-tracer to create more realistic renderings. Parameters, such as lighting, can also be edited, and can compile DICOM image stacks into three-dimensional models for medical personnel.

“Photoshop is about delivering cutting-edge innovation that really pushes the boundaries of digital image editing,” said Kevin Connor, vice president of product management for professional digital imaging at Adobe. “This version is no exception with some stunning new imaging technology that complements our work to bring more control, simplicity and speed to everyday tasks. By streamlining the most popular workflows for the professional, technical or home user, Photoshop CS4 brings new levels of accessibility to the gold standard in digital imaging software.”

Adobe is shipping Photoshop CS4 in October for $700, while Photoshop Extended will sell for $1000.
