CS4 features smoother panning and zooming,
allowing faster image editing at a high magnification. The interface is more
simplified with its tab-based interface making it cleaner to work with.
CS4 features a new 3D engine allowing the conversion of gradient maps to 3D
objects, adding depth to layers and text, and getting print-quality output with
the new ray-tracing rendering engine. It supports common 3D formats; the new
Adjustment and Mask Panels; Content-aware scaling; Fluid Canvas Rotation and
File display options. The Content-aware scaling allows users to intelligently
size and scale images, and the Canvas Rotation tool makes it easier to rotate
and edit images from any angle.
Adobe released Photoshop CS4 Extended, which has the features of Adobe
Photoshop CS4, plus capabilities for scientific imaging, 3D, motion graphics,
accurate image analysis and high-end film and video users. The faster 3D engine
allows users to paint directly on 3D models, wrap 2D images around 3D shapes
and animate 3D objects. As the successor to Photoshop CS3, Photoshop CS4 is the
first x64 edition of Photoshop on consumer computers for Windows. The color
correction tool has also been improved significantly.
