CyberCollege TV Production Modules 26 - 30

Virtual reality sets

are computer generated

Some electronic graphic systems are dedicated. This means that they

are hardware based and designed to just do specific things

Instead of a relatively smooth mix of colors from infrared to ultraviolet this light source typically has sharp bands or spikes of color, primarily in the blue-green area

standard fluorescent light

For decades the primary type of lighting instrument used in studios has been the

Fresnel light

A device that attaches to a frame at the front of Fresnel lights that softly cuts off the edges of the beam is referred to as

barn doors

Motion tracking

can animate cartoon characters; uses points on the human body as references points

Reflected light meters

can be fooled by windows, lights, and bright backgrounds; assume average subject matter; can be used at the camera position

Another name for light quality is

coherence

A type of studio light that reduces power consumption, heat, and provides a soft illumination is

color-balanced fluorescent

In video-related computer programs rendering is the process of

computer-based "fleshing out" of video illustrations and effects from basic data

Both film and electronic animation make use of the concept of layering. This is commonly used to

depict action taking place at different distances

A lighting instrument that can project a hard, sharply-defined area of light is a

ellipsoidal spot

A soft light effect can be created with

flat lighting; an umbrella reflector; a diffuser

If you wanted to bring out maximum surface detail in a subject you should use a

hard light

Compared to sunlight, incandescent light

has a more reddish-yellow light

The best type of light meter for setting up and balancing the intensities of various studio lights would be a(n)

incident mater

Daylight color temperature changes with

latitude & longitude; the time of day; the cloud cover

The problem with using dimmers as they relate to color temperature is that they

lower color temperature

You can vary light intensity on a subject by moving lights closer and farther away. If you wanted to cut the intensity of a light to one-fourth of its original intensity you would

move the light twice as far away

The tungsten-halogen lamps used in TV production are commonly called

quartz lights

In using quartz lamps you must

remember to replace them using a cloth to make sure you don't get fingerprints on the lamp; not subject them to severe jolts while they are on; respect the fact that they get very hot

Sunlight contains more red light during sunrises and sunsets because

sunlight must travel through more of the earth's atmosphere at these times
