The Intuos3 Art Marker will use the new attribute 'rotation' which will be available in the brush menue of Photoshop CS2. The main advantage over the 'tilt' feature will be, that you do not have to tilt the pen in order to having its rotation recognized by the tablet. That should grant better control over flat brush tips.
"The new rotation sensing technology of the Intuos3 Art Marker will be supported by Adobe Photoshop CS2 and Adobe Illustrator CS2. Matthew Richmond, founding partner and creative director, The Chopping Block, an award-winning graphic design studio in New York, comments: “The Wacom Intuos3 Art Marker and Adobe Illustrator CS2 completely change the landscape of digital drawing. The results are remarkable - the control over rotation, stroke and pressure approaches the response of pen and brush with paper. It just feels right.”
Additionally Wacom has been working with Corel, who is developing a set of customised brushes for Painter IX that will support the new Art Marker. These will be available to download from the Corel and Wacom website shortly after the pen is launched. “Never has technology so faithfully captured the traditional art experience,” said Chris Boba, product manager for Corel Painter IX. “The combination of Wacom’s new Intuos3 Art Marker with the new lifelike brushes in Painter IX enables artists to transcend the digital divide and explore a brave new world of creative freedom.”
