Color grading

Color grading is the process of altering and enhancing the color of a motion picture or television 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 using optical filters.

Using digital grading objects and color ranges within the scene can be isolated with perfect precision and relit or adjusted. Color tints can be manipulated and visual treatments pushed to extremes not physically possible with laboratory processing. Special digital filters and effects can be also applied to the images.
