Descripción

Computer-generated visual effects are now used extensively in feature films, commercials, music videos, and multimedia. The backbone of this process, the final and most important step, is known as digital compositing. The Art and Science of Digital Compositing is a comprehensive reference that provides a complete overview of the technical and the artistic nature of this process. This book covers a wide range of topics from basic image creation, representation, and manipulation, to a look at the visual cues that are necessary to create a believable composite. Designed as both an introduction to the field as well as a valuable technical reference, this book should be of interest to both novices and professionals alike.

Written by a working professional in the visual effects industry, the book provides over 250 different images and illustrations (including a 40-page color insert) as well as a complete glossary of compositing and visual-effects terminology. Also included are in-depth case studies from well-known films such as Speed, Independence Day, and Titanic.
