Fastest Photoshop Acceleration Available

With four AT&T 32-bit DSPs, the Thunder family offers the same fast Photoshop acceleration previously only offered by Radius' highly acclaimed PhotoEngine Photoshop accelerator. By incorporating PhotoEngine technology into the Thunder series of cards, users gain Adobe-charged Photoshop acceleration for resamples, filters, mode conversions, and onscreen graphics acceleration for display of Photoshop CMYK images.

PhotoEngine also provides increased productivity to creative professionals that work primarily in the printing industry's CMYK color space right from their display. Those who work with detailed images can operate directly in CMYK format without the performance degradation associated with display redraw of Photoshop CMYK images.

In addition to the acceleration of other functions such as filtering and resampling, this feature will allow users to spend more time exploring their creative options.

Color Matching Made Easy With ColorComposer

Radius' color matching software, ColorComposer, is bundled with the new Thunder cards. ColorComposer enables users to match their display's appearance to other displays in their work group or even to various color printers. ColorComposer ships with a printer reference file showing numerous color patterns.

Users may print the file, then adjust the color patterns on-screen until they match the print out. This works for any display/printer combination, and is a form of "perceptual color matching," as close a match as the user's eye can distinguish.

ColorComposer also offers simple control over white point settings, a critical component to matching the white color of paper, which varies widely from the yellow tones of newsprint to the bright white of laser printer paper. Included as part of ColorComposer's Basic Tools are on-the-fly adjustment of the display white point, image linearity (display gamma settings) and image balance.

A filing system allows the user to save any number of configurations for matching colors in different lighting environments and for matching multiple color displays or printers.

Another unique feature of ColorComposer is The Matching Game - an easy-to-use tutorial that displays a sequence of random colors that the user has to try to match on screen. The game offers a unique and fun way to teach basic color concepts to people just getting started using color.

Radius Super Resolution

Radius' Super Resolution of 1600 x 1200, available in 24-bit mode on the GX 1600 model (all models support 1600 x 1200 x 8-bit), nearly doubles the maximum built-in video resolution of 1152 x 870 available on some high-end Macintosh and Power Macintosh systems. Super Resolution displays 92 percent more pixels which provides creative professionals with the greatest image detail, smoother graphics and maximum desktop area available on the Macintosh today.

Super Resolution will dramatically enhance the professional's view of intricate Quark, Illustrator, Acrobat and Freehand documents. The Super Resolution feature of the Thunder series is designed to complement Radius' line of high resolution monitors, the PressView 21 T and SuperMatch 21 T XL.

The combination of these products results in the ultimate color desktop solution that delivers the fastest drawing speed, greater desktop workspace, and accurate color matching for greater performance and productivity.

On-the-Fly Resolution Control with Dynamic Desktop

Bundled with the Thunder series, Radius' Dynamic Desktop software enables users to change resolution and bit-depth on the fly without having to reboot or re-launch applications. The easy-to-use pull-down menu and hot keys option, allows creative professionals to navigate quickly and easily through complex documents and images using the hardware pan and zoom function.
