ABSTRACT
Motion picture lights fall into several general categories: HMIs, tungsten Fresnels, tungsten open face lights, LED lights, color-correctflu-orescents, practicals, and sunguns. Lighting units can generally be divided into those that output daylight balance or tungsten balance light. While most lighting units are inherently either daylight or tungsten, some types of lighting units can easily be changed to either color or, in some cases, changed to greenscreen, fluorescent, or many other color balances. All LED lighting units for filmmaking contain multiple light-emitting diodes. However, variations in manufacturing processes can result in LEDs having differences in their color and output. Much of the time, lighting day exteriors will depend more on grip equipment such as silks, nets, and flags in addition to whatever lights or reflectors may be working on the scene.
