Knowra Theatrical lighting Theatrical lighting Theatrical lighting uses light to make stage action visible and shape its atmosphere, directing attention through illumination, color, shadow, and timing.
Stage lighting instrument : A fixture designed to produce, shape, or project light for performance. Fixtures determine the beam shape, color options, and direction available to a lighting design.
Luminous flux : The total visible light emitted by a source, weighted by human visual sensitivity. It distinguishes a fixture's overall light output from the brightness of a lit surface.
Stage lighting design : The planning of illumination for a performance to support visibility, composition, mood, and dramatic action. It is the broader design practice that organizes lighting choices into a coherent production.
Adolphe Appia : A Swiss stage designer and theorist who advocated integrating light, space, and three-dimensional acting. His theories helped establish lighting as an active element of theatrical composition.
Gas lighting : A form of illumination produced by burning manufactured gas in lamps or burners. Its adoption in theatres enabled brighter, more controllable illumination than candles.
Ellipsoidal reflector spotlight : A stage lighting instrument that uses an ellipsoidal reflector and lenses to project a sharply controlled beam. Its shutters and framing accessories let designers isolate performers or define precise areas.
Illuminance : The amount of luminous flux arriving on a surface per unit area. It describes how much light reaches a performer or scenic surface.
Followspot : A manually operated spotlight that tracks a performer across a performance space. It keeps a moving performer visible when general stage lighting cannot follow them.
Stanley McCandless : An American lighting designer and educator known for a systematic approach to stage illumination. His method of dividing stage areas and balancing warm and cool light shaped lighting practice.
Limelight : An intense light produced by heating lime with an oxyhydrogen flame. It became a powerful theatrical spotlight before electric stage lighting was widespread.
