Photographers’ gobbledygook can be confusing! This photography dictionary will help you find the real significance behind that jargon.
Kelvin(K)
Unit of temperature in the SI (Système International) system of units. Kelvin is used to measure the colour temperature of light. Daylight films are designed for colour temperatures between 5200K and 5800K.
Keystoning
Converging verticals can make a building appear to be falling down (wider at the bottom than the top), this can be corrected by making sure the film plane is parallel to the photographed surface using either a Shift Lens or camera movements. It can also be corrected within Photoshop. Keystoning is also the term for the effect of a tilted (up or down) projector.
(see Camera movements, Converging angles, Movements, Photoshop, Rising front & Shift )
