The Kelvin is the definitive unit of temperature, with zero degrees Kelvin representing absolute zero. Freezing point is approximately 273 degrees Kelvin and 1 Kelvin is equivalent to 1 degree Celsius. Video Production Companies and their lighting departments refer to the colour or temperature of lamps used for lighting. Therefore Kelvin can be used as a unit of Colour Temperature Measurement. A 10K light will not mean 10 kW, but this means 10,000 Kelvin.

Keying is a common technique used throughout the video industry and film sector. The common types are blue screen or green screen, however the process is fairly simple. An individual or object is filmed against a background (blue screen or green screen) and removed from this background with another background being substituted. Weather presenters on news bulletins, live event video production where an individual presenter may stand in front of a screen with the background changing etc – these are typical examples of keying. In films, complex action sequences or CGI can be replaced in the background to dramatic effect. Keying is a very useful tool in video production. (Post production)
A kick is an object which has a light reflection cast on it, caused by another object. Live event filming companies or film crews pay particular attention to making sure that footage taken is relatively free from objects causing a kick. (Grip / Lighting)
