KELVIN

The Kelvin (K) scale is named af­ter Lord Kelvin, a 19th-cen­tury Bri­tish physi­cist. A Kelvin is a unit of mea­sure for tem­per­a­ture, and in pho­tog­ra­phy it’s used to de­scribe the colour of dif­fer­ent light sources, and of nat­u­ral light at dif­fer­ent times of the day.

COLOUR CAST

Colour casts are tints of cool blue or warm or­ange that need to be cor­rected in or­der to cre­ate more faith­ful colours.
