Adobe Photoshop CS4, the latest version of Adobe's flagship image-editing program, will hit the streets practically on the heels of Photoshop CS3, which debuted a little less than 18 months ago.

Extended exclusives

If you pop for the Extended version, you'll notice a couple of new tools gracing your Tools panel called 3D Rotate and 3D Orbit, as well as a new menu stuffed full of commands like New Mesh from Grayscale, Invert Visible Surfaces, and Create UV Overlays.

With Photoshop CS4, Adobe has stepped rather firmly into the realm of 3-D modeling, giving you the ability to convert 2-D into 3-D, along with a fair amount of control over object textures and lighting. You can even paint directly on the surface geometry of a model in real-time and open models downloaded from Google right there in Photoshop. Adobe also added a reparameterize command that can quickly rebuild the surface geometry of your 3-D object for smoother painting.

If you're a video editor, you may appreciate Extended's single-letter keyboard shortcuts, smooth display of no-square pixels, and the ability to preview and export audio.
