THE NEW VERSION of Photoshop will recruit the computer's graphics chip for the first time.
John Nack, principal product manager for Adobe Photoshop said CS4 will use the graphics processing unit, or GPU.
This will mean that it will be better able to zoom in and out or rotate the canvas so that artists can reorient an image for the best sketching angle, display and manipulate 3D objects, and handle colour correction.
Nack said that GPU power advancement meant that there was an enormous wealth of cycles Photoshop could take advantage of.
While graphics chips are designed to blast pixels to the screen, they are not really designed to shove everything back to the main processor for further work.
This means that photoshop will not be able to accelerate all processes. It also means that Adobe has to work more carefully on hardware compatibility.
Later a GPU-enabled feature called Pixel Bender, which lets people apply special effects quickly, will be added into CS4 as a free update.
Upgrade prices are $199 for the Photoshop CS4 and $349 for CS4 Extended. CS4 extended is more for scientific applications, dealing with medical imagery and creating 3D objects.
Photoshop Elements will hit the shops for about $100 and its online Photoshop Express for free.
It will be on the shelves in October.
