Photoshop CS4: Smart Objects explores the creation and use of Smart Objects, one of the most technically demanding tools in Photoshop. Deke McClelland walks through the four primary purposes of Smart Objects, and focuses on one of their most practical advantages, non-destructive transformations. This feature allows any object to be manipulated in any way, while still maintaining its original pixel information. Finally, Deke shows how to crop compositions without affecting a single pixel, even in masks. Exercise files accompany this course.
