Qualities of Stage Lighting

Direction, Intensity, Movement/Queuing, Instrumentation, Color

Direction (Qualities of Stage Lighting)

The direction from which the light is coming from. Front light, side light, downlight, up-light, etc.

Intensity (Qualities of Stage Lighting)

The amount of light or brightness of the light which is striking the stage and/or the performers, controlled through the control system and/or console

Movement/Queuing (Qualities of Stage Lighting)

Movement of a practical or special source of lighting on stage. Movement of a light source such as a follow spot or automated lighting fixture Lighting cues: one light or a set of lights fades out while another fades up

Instrumentation (Qualities of Stage Lighting)

The type of lighting instrument used and the quality of light it produces

Color (Qualities of Stage Lighting)

The use of color media in front of a conventional light source to produce a certain color or through a stage lighting fixture that has different colored light emitting diodes (LED's).

Functions of Stage Lighting

Selective Visibility/Focus, Plausibility, Atmosphere, Revelation of Form, Composition

Selective Visibility/Focus (Functions of Stage Lighting)

putting emphasis on the part of the stage in which the action takes place. This can be done by increasing the intensity in the desired location, changing color, or direction.

Plausibility (Functions of Stage Lighting)

The appropriateness of the lighting design. What time of day is it? Where does the action take place? Indoors or outdoors? Does the show take place in a realistic setting

Atmosphere (Functions of Stage Lighting)

Not the setting of mood. The creation of a place especially suited to the actor or setting at a specific moment. The quality of light in different places; a mountaintop is different from a recently burnt down house

Revelation of Form (Functions of Stage Lighting)

The giving of shape to scenery or actors on stage. If something is lit from the front only it will appear to be flat and two-dimensional even if it is a three-dimensional object. The use of lighting from different directions gives objects multiple dimensionalities

Composition (Functions of Stage Lighting)

The tying together of all the visual elements. Similar to a graphic designer, a lighting designer uses line, color temperature, value, proportion and mass to achieve balance, focus, and emphasis and an overall stage picture, "painting the stage with light". The overall pictorial effect. This is the hardest "function" of stage lighting to achieve. Communication with other designers and the director is key.

Conventional

uses a "lamp" as its light source (aka - lightbulb) and is dimmed with a "dimmer"

LED

uses a light "engine" that is made up of various colors of Light Emitting Diodes also know as "LED's", controlled by "DMX"

Automated

an intelligent/robotic fixture that can move (pan and tilt), change color, and change the qualities of light it produces such as strobing, spinning or applying special effects to the light

Practical

examples include a household lamp on a desk or living room, a lit sign, some practical's may also be "props" handled by performers

Special effects

examples include UV (aka "black") lights, lasers, and audience "blinders"

Spot or Profile fixture

An LED or Conventional that gives off a sharp edge to eliminate a specific spot

Wash fixture

A fixture with a very soft edge and is often used as houselights

PAR light

Creates an oval shaped diffused light and has various sizes and wattages

Strip light

A row of lights with colored gels in them that either are used up high or down low

Cyclorama fixture

Back Drop Lighting, Ground Row, and Horizon lighing

Lighting Designer (LD)

Creates the light plot, focusing, and design concept to illuminate actors, create atmosphere, and draw audience attention

Master Electrician (ME)

Manages the lighting equipment, oversees the installation (hanging, cabling), focusing, and maintenance of fixtures.

Lighting programmer

Works with the lighting designer to program the lighting console, creating the cue list, looks, and effects for the show

Light board operator

Runs the console during rehearsals and shows, often performing daily checks and troubleshooting

Follow spot operator

Manually operates spotlight fixtures to follow performers.

Deck Electrician

An electrician who is there during the show and does whatever he needs to do while the show is going on

Photometrics

the science of measuring light as perceived by the human eye, quantifying how it is emitted, distributed, and received

Luminous Flux (lumens)

Total light output

Luminous Intensity (Candela)

Luminous intensity from source

Illuminance (Lux)

Light on a surface aka

DMX

DMX is a universal control protocol used to control lights and equipment like fog machines. Each universe has 512 addresses, and each address controls one part of a device

512

Thats how many channels there are in one Universe of DMX

Ethernet based DMX protocols

sACN, also called Streaming ACN, supports up to 63,999 universes, or 32,767,488 channels. Art-Net supports up to 32,768 universes, or about 16 million channels. ETC Net3 is a version of sACN.

What type of DMX is “Streeming ACN (sACN)”

Ethernet based DMX

RDM

a two-way communication protocol used with DMX lighting systems to let a controller configure and monitor compatible lighting devices remotely.

Media Server

A specialized computer runs software that stores and manipulates video content and applies visual effects. It can synchronize video playback with stage-lighting cues.

DMX Architectural Lighting

DMX is also used for Architectural lighting controls systems

Color Temperature

The lower the temperature, the "warmer" or more amber the light appears, the higher the temperature, the "cooler" the light appears

RGB, RGBA, lime, 7colors

four examples of different types of LED Arrays or Engines

AMPS

(amount of current) is the measured amount of electricity.

VOLTS

(amount of emf) is how powerful the potential flow of power is, not the amount.

OHMS

(amount of resistance) slows the flow of electricity

WATTS

(amount of energy used) is how much gets done. (examples include heating elements, motors, lamps)

2-fer, 3-fer, True 1

Types of typical Stage Lighting Connectors

Plot

A stage lighting plot is a detailed schematic drawing that serves as the technical blueprint for a production's lighting design. It tells the lighting crew exactly where to hang every fixture and how to configure them

Essential components of Stage Lighting Plot

Location of the light, Orientation of the light/direction, what kind of light it is, the gel or color of a light, Size of the sage or lighting area

Types of Lighting Paperwork

Lighting Plot, Cue sheet, Instrument schedule, Magic sheet, and Channel hookup
