As prevously rumoured on Pocket-lint, Adobe has released a beta version of Photoshop CS3 for both Mac and Windows PC to try out.

This is the first version of the software that runs natively on Intel Macs, rather than through Rosetta. The final shipping date of the application isn't expected until Spring 2007, and this beta release gives Adobe the chance to get user feedback on features and issues before the full release.

The beta also includes a pre-release version of Adobe Bridge, which Adobe are calling a “major upgrade,” and a preview release of Adobe Device Central.

This latest addition to the CS family lets Photoshop users design, preview, and test mobile content on a range of small screens.

“This is an exciting time for the Mac, and Adobe wanted to ease the move to a new Intel-based systems with a preview release of Photoshop CS3,” said John Loiacono, senior VP of Creative Solutions Business Unit at Adobe.

“We still have some surprises in store, but this beta gives customers an early chance to see the power of another great Photoshop release, optimised and tuned to run natively on the latest hardware and operating systems.”

To download the beta, you have to register with Adobe first. To use the beta until the full version comes out in the Spring, you have to have a valid serial number from Photoshop CS2 or the Creative Suite. Otherwise, the beta will expire after 2 days.

The editor of Photoshop User magazine, Scott Kelby, has already posted a roundup of the top ten new features. They include a new, customisable user interface, big improvements to Camera Raw, an easy Quick Selection tool, and an even better Curves dialogue.
