Adobe has released a beta version of Photoshop CS3, the next version of the image editing software that's the first to run natively on Intel-based Macs. The beta also runs on Windows XP and Vista.

The beta is available to all rom the Adobe Labs Web site, but will time out after two days unless a serial number from Photoshop CS2 or a bundle including the software such as Creative Suite 2 and Production Studio is entered.

The Photoshop CS3 beta also includes a pre-release version of a major upgrade to Adobe Bridge, as well as a preview release of the all-new Adobe Device Central. Photoshop customers can use Adobe Device Central to design, preview, and test compelling mobile content, created specifically for smaller screens. This new tool, integrated in the Photoshop CS3 beta, simplifies and accelerates the creation of mobile content through a preview environment and built-in device profiles.

“This is an exciting time for the Mac, and Adobe wanted to ease the move to new Intel-based systems with a preview release of Photoshop CS3,” said John Loiacono, senior vice president of Creative Solutions Business Unit at Adobe. “We didn’t want to leave Windows customers out of the party, so the beta is available to everyone in the creative industry's most passionate user community -- no matter what their platform choice. We still have some surprises in store, but this beta gives customers an early chance to see the power of another great Photoshop release, optimized and tuned to run natively on the latest hardware and operating systems.”

In related previews of future technologies, Adobe has also released two new Web tools as beta releases. Adobe CSS Advisor is a new Web-based community site to easily identify and resolve browser compatibility issues. Web designers and developers can contribute their own issues, comment on existing issues, or become an editor to participate in driving the site's future.

Also introduced is a beta release of Adobe Spry framework for Ajax, a designer-focused solution for adding the interactive power of Ajax when developing rich, dynamic wWb-sites.

The Photoshop CS3 beta will expire soon after the launch of Photoshop CS3 in Spring 2007. Details on final pricing, system requirements and availability have yet to be determined.
