Color grading
Color grading is the process of altering and enhancing the color of a motion picture, video image, or still image either electronically, photo-chemically or digitally. The photo-chemical process is also referred to as color timing and is typically performed at a photographic laboratory. Modern color correction, whether for theatrical film, video distribution, or print is generally done digitally in a color suite.
== Telecine ==
(詳細はlive television broadcasts and they turned to broadcasting feature films from release prints directly from a telecine. This was before 1956 when Ampex introduced the first Quadruplex videotape recorder (VTR) VRX-1000. Live television shows could also be recorded to film and aired at different times in different time zones by filming a video monitor. The heart of this system was the ''kinescope'', a device for recording a television broadcast to film.〔Kallenberger, Richard H., Cvjetnicanin, George D. (1994). ''Film into Video: A Guide to Merging the Technologies''. Focal Press. ISBN 0-240-80215-2〕
The early telecine hardware was the "film chain" for broadcasting from film and utilized a film projector connected to a video camera. As explained by Jay Holben in ''American Cinematographer Magazine'', "The telecine didn't truly become a viable post-production tool until it was given the ability to perform colour correction on a video signal."〔Holben, Jay (May 1999). "From Film to Tape" ''American Cinematographer Magazine'', pp. 108-122.〕
Today, telecine is synonymous with color timing as tools and technologies have advanced to make color timing (color correction) ubiquitous in a video environment.
