Description:
This is an excellent guide to using advanced channel-processing techniques and other procedures in Adobe Photoshop. The writers assume that you're already familiar with this image editor, but that you want to learn how to use channels, alpha channels, and masks creatively and effectively in your work. ("Chops" is an acronym, created by the authors, for channel operations.) They also assume that most of your work focuses on creating composite images. You learn how to use layers, Calculations, blue-screen and green-screen techniques, and paths to achieve various effects. Historical overviews help place each given topic in perspective. The guide discusses why and when you'd want to use each technique, providing a highly valuable real- world emphasis. Photoshop Channel Chops features Photoshop 4.0 for Macintosh in its screen shots and tips, but because the writers present a great deal of theory as they teach the technology, users of previous versions of the software and Windows can easily apply what they learn to their own projects.
