  1. Lighting For Television The art of control and effect

  2. The Principles of Light • Light is part of the electromagnetic energy spectrum. X-ray and Gamma rays Violet Indigo Blue Green Yellow Orange Red The Electromagnetic Spectrum Radio and Communications freq. Audio 20 Hz – 20 KHz

  3. 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.

  5. 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.

  8. 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

  11. 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 shadow’s edge produced by a light fixture

  13. 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.

  14. 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.

  15. 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)

  16. The Kelvin Scale • Measures the relative Reddishness or bluishness of light Kelvin Scale 20,000 K 15,000 K 5600 K 3200 K 2800 K 2200 K 1200 K Outdoor light on a stormy day Outdoor light on a cloudy Day Outdoor light on a beautiful sunny day (Approx) Studio lighting (Quartz/Halogen light fixtures) Fluorescent lighting fixture Incandescent Light fixture Candle light
