Pulling a key from a greenscreen is one of the basic skills for any compositor but only the most skilled artists can create the illusion of the integration of an extracted green screen element with other CG layers to make it look like it was shot at the same time, with the same camera and lenses under the same lights. For a compositor there is more to see than just green pixels and an alpha channel. The elaboration of a green screen or blue screen requires both fine artistic eye and a methodological mindset.
Professor Victor Perez has designed this two-part course to teach you all the available keying tools in Nuke X and how to use them to pull a key as a real pro. In part one of the course, Victor provides a detailed overview of concepts every artist should know regarding keying and then dives into covering the keyers available in Nuke X. 'The Art and Science of Green Screen Keying, Part 1' contains over five hours of instruction as well as footage files (available with our premium membership).
