This self-paced guide to Adobe Photoshop CS4 is ideal for beginning users who want to learn key Photoshop concepts and techniques, while readers who already have some experience with Photoshop can use this book to learn Photoshop CS4's more advanced features and newest tools. Using step-by-step, project-based lessons, each chapter walks readers through the creation of a specific project, with successive chapters building on the reader's growing knowledge of the program. With Photoshop CS4, users can edit their images safely with non-destructive Adjustment panels or the new Camera Raw 5 plugin. Anyone who wants to create a composite will benefit from the revamped Photomerge® tool, which now enables users to create full 360-degree panoramas, while the new Quick Selection tool lets users select pixels not just by color, but by texture and shape as well. In addition, professionals in film and television, manufacturing, architecture and engineering, and medicine and science can use Photoshop Extended to enhance images for analysis and presentation, use its built-in 3D and motion support for time-based cloning and healing on video layers, create 3D model visualizations, export 3D models from 2D images, and more.
