These are screenshots of selected features from my review of Adobe Photoshop CS3 Extended.
Stacked Menu Buttons
Photoshop CS3 Extended makes extensive use of stacked menu buttons to allow quick access to more features.
Curves
Photoshop CS3 Extended continues its use of curves to make color and lighting adjustments quick and precise.
Cloning
Photoshop CS3 Extended offers powerful cloning tools to allow photographers and designers a lot of freedom in creating special effects.
Refine Edge
Photoshop CS3 Extended offers a new selection tool called quick select that includes powerful features such as edge refine.
Smart Filters
Photoshop CS3 Extended's new smart filters feature allows photographers to edit several filters without starting over each time. To access this capability a layer must be made a smart object first.
