Ch. 1 An Introduction to Designing w/ Light - Coggle Diagram

- - - - One of the four controllable qualities of light; the direction, shape and size, quality (clarity or diffusion), and character (texture) of light.
      - (1) the direction from which the light approaches an area, actor, or object; (2) the shape and size of the area that the light is covering; (3) the quality of the light—its cohesiveness (clarity or diffusion); and (4) the character of the light—its texture (smooth, uneven, patterned, hard- or soft-edged, and so forth).
    - - In stage lighting, the location onstage where the light from an instrument is directed.
      - The focus of the lighting instruments determines both the pattern and position of highlights and shadows cast on the actors and their environment.
    - - A mechanical dimmer with movable slats or an iris to block or allow light to pass. Typically used in fixtures with non-dimmable sources such as followspots and intelligent/moving light fixtures.
  - - - Generally, some type of action involving lighting; usually the raising or lowering of the intensity of one or more lighting instruments.
    - - A lighting instrument with a high-intensity, narrow beam of light; mounted on a stand that allows it to tilt and swivel so that the beam can “follow” the actor.
    - - he intensity range can vary from total darkness to painfully brilliant white light.
      - Intensity can also be controlled by other means, including varying the color, using different wattage lamps, or by using dousers to mechanically block the light.
  - - - A lighting fixture that can be remotely controlled to move, change color/beam shape, and so forth. Also known as an intelligent light fixture.
    - - (1) the timed duration of a light cue —that is, the length of time it takes for the lights of one cue to come up or go out
      - (2) the movement of onstage lights, such as a lantern or candle that an actor carries across the stage
      - (3) the movement of an offstage light source, such as a followspot or moving light fixture
  - - - One of the four functions of stage lighting: to light the stage in a manner that supports the production concept.
- - - - One of the four functions of stage lighting: the ability of light to reveal three-dimensional form.
      - our perception of the forms of actors or dancers can be changed or modified by controlling and manipulating the patterns of highlight and shadow on their faces and bodies.
      - The use of sidelight highlights and accentuates the edges and vertical line of the body and makes those actors or dancers seem taller and thinner than they are in reality.
      - Direction is the primary element used in modeling, although intensity, movement, and color all affect modeling to a lesser degree. A change in any or all of these variables will inevitably result in an apparent change of form and feeling in the object being lit.
    - - Any light striking the side of an object relative to the view of the observer.
    - - One of the four functions of stage lighting: the ability of light to create a mood.
  - - - One of the four functions of stage lighting: the ability of light to direct the audience’s attention to a specific location.
    - - A single set in which all of the play’s locations are always visible and the audience’s attention is usually shifted by alternately lighting various parts of the set.
    - - Those areas of the stage on which specific scenes, or parts of scenes, are played.
    - - A common example of the use of selective focus occurs when the lighting designer reduces the intensity of lights on one area of a unit set while increasing it on another.
      - lighting designs for most interior settings. In these designs the lights are usually brighter in the major acting areas than they are in the upstage corners of the set where there is little, if any, action during the course of the play.
      - The most extreme use of selective focus can be seen in almost any musical, where the audience’s attention is directed to the lead singer by one or more followspots that focus on the singer while the rest of the stage lights dim or change color to emphasize the mood of the song.
  - - - Having to do with movement. In the case of lighting design, having to do with moving lights.
  - - - The producer; director; and scenic, costume, lighting, and sound designers who develop the visual and aural concept for the production.
    - - In the context of lighting fixtures, those instruments designed to be used outside the studio. Typically these fixtures are small, lightweight and are equipped with a telescoping stand.
