In Photoshop CS4: Layer Masks in Depth, senior trainer and photographer Jan Kabili takes an in-depth look at using layer masks to create professional-looking image composites and make targeted photo corrections. Jan examines some common situations in which layer masks are the key to creating convincing image composites. She demonstrates practical ways to enhance photos with layer masking, including masking adjustment layers and Smart Filters to affect part of a photo. She explains how to use layer masks to combine different exposures of the same scene, and teaches how to work with vector masks to achieve a clean, graphic look. Exercise files accompany the course.
