Lighting For Television The art of control and effect
The Principles of Light Light is part of the electromagnetic energy spectrum. X-ray and Gamma rays Audio 20 Hz – 20 KHz Radio and Communications freq. The Electromagnetic Spectrum Violet Indigo Blue Green Yellow Orange Red
Lighting Terminology Color Temperature: The relative reddishness or bluishness of light. Measured in degrees Kelvin. Primary Colors: For light the primary colors are Red, Blue, & Green Photographic principle: Lighting design utilizing 3 lights to light a subject. Gel: A colored filter that allows only certain light to pass through the filter. Fresnel: A hard light that is a common type of light fixture for a TV Studio.
Lighting Terminology (cont.) Hard light: A directional light sources that produces sharp falloff (shadows have edges) Soft light: Diffused light that produces few shadows. EFP Floodlight: Used for portable lighting situations. Usually consists of a bright halogen bulb – Very hot to touch. Ellipsoidal Spotlight: An adjustable lighting fixture that allows the lighting director to focus light where he/she would want it.
Lighting Terminology (cont.) Flag: Cloth or material that will block light from an area of a set. Scoop: A light fixture that has no lens and produces soft light. Kelvin Scale: the scale used to measure the relative reddishness or bluishness of light. Light Plot: A detailed diagram that shows the placement of lights on the light grid. Grid: A support system that lights are hung from
Lighting Terminology (cont.) Raceway: The electrical grid that supplies electricity to the grid. Usually it is a complex array of wires. Light board: A control panel that allows an operator to control light intensity to each circuit. Gaffer: An assistant lighting director. Falloff: The intensity of the shadows edge produced by a light fixture
Lighting Terminology (cont.) Background light: The purpose of the background light is to establish a "base level of overall lighting" on the set, and to illuminate the set pieces. Barndoors: The flaps attached to the front of the instrument, they are manipulated to prevent light from striking unwanted areas. Diffusion: Diffusion scatters light, creating soft, somewhat blurred shadow edges, and less severe modeling.
Lighting Terminology (cont.) Scrims: A wire screen used to cut down the amount of light emulating from an instrument. It is inserted between the lens and the barndoors. Side light: Side light is sometimes used as an alternative to the standard three point lighting setup.
The Photographic Principle Most common type of lighting design Or 3 point lighting –Key light –Back light –Fill light Fill Light Soft light Back Light (hard or spot light) Key Light (hard or spot light)
