Color Timing
1. 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. Considering such achievements in digital imaging, the artist has the ability to “paint” the image, thus the names “colorist” or “color painter” have become most applicable.
