20. Introduction to Digital Compositing

Half Day / Beginning

This course covers the basic terms and processes required to understand compositing, particularly as it applies to a production environment. It details the basic operations used to combine multiple image elements into a single seamless image or image sequence, including how to prepare and repair elements, and what is needed for a clean final composite.

Who Should Attend
Anyone who needs to create an image or sequence of images that contains elements from different sources. The course is presented from a production viewpoint, but the concepts apply to graphic design, engineering, scientific visualization, and fine art.
