We’ll get into this more later in the book. It is possible for the luminance of an image to be well under legal levels, but because of a combination of saturation and luminance, the legal gamut levels can be exceeded. These gamut levels are the legal amounts-or values-of certain colors. Not all waveform monitors or vectorscopes can monitor gamut levels. (There are other ways to measure the signal other than IRE, such as in millivolts.) Also, as our delivery systems become more and more digitally based, “gamut” is also included in “legal” levels. The brightest pixels are not to pass 100IRE when monitoring luminance only or, when combined with chroma, cannot pass 110IRE.
Each duplicator or broadcaster sets their own specific requirements for video levels, but in general these levels adhere to national and international standards and describe that the darkest portions of the luminance of the picture can not fall below 0IRE for NTSC digital video (and most other international video of any type) or 7.5IRE for composite NTSC in the United States. This usually implies broadcast, but can also pertain to duplication. Legal: For video-based images, “legal” means that the brightness and color saturation of an image does not exceed minimum or maximum levels that have been determined for a specific delivery channel for a video. * use color correction to advance a story * master primary and secondary color correction techniques * fix poorly exposed shots and shots with color casts Packed with explanations, tips, and concepts that build on each other, you will learn how to: Featuring techniques performed in a variety of color correction software applications (DaVinci Resolve, Apple Color, Synthetic Aperture's Color Finesse, and more), this book turns what has long been a misunderstood "black art" into a set of skills that any colorist, editor, independent filmmaker, or motion graphics artist can begin to master. This book allows you unprecedented access to the way the masters of the craft approach their work.Ĭontaining decades of industry experience and professional colorist know-how, this book provides an understanding of what top-tier colorists look for in an image and how they know what to do to make it great. The only guide to the art and technique of color correction based on the invaluable knowledge of more than a dozen of the top colorists in the world.
