Photoshop CS3 gives you the ability to work more productively, edit with unrivalled power, and composite with breakthrough tools.
New features for productivity include:
Editing tools new to CS3 are the Clone Source palette and nondestructive Smart Filters. Other features such as the Brightness/Contrast adjustment and Vanishing Point module were enhanced.
The Black and White adjustment option improves users control over manual grayscale conversions with a dialog box similar to that of Channel Mixer. Compositing is assisted with Photoshop's new Quick Selection and Refine Edge tools and improved image stitching technology.
This is a 30-day trial.
