1. Unveiling the Fundamentals: A Comprehensive Review

Before embarking on your stage lighting journey, it’s crucial to grasp some essential theatrical concepts. Let’s delve into a review covering theatrical spaces, lighting terminology, color, electricity, and instruments.

1.1 The Theatrical Space: Setting the Stage

The theatrical space encompasses the stage and the house, the area where the audience sits. Different stage configurations, such as proscenium, thrust, and arena, dictate the viewing experience and lighting requirements. Understanding these spatial arrangements helps you adapt your lighting designs for maximum impact.

Architectural drawings, namely the groundplan and sectional view, provide a visual blueprint of the theatre space.

• The groundplan offers a bird’s-eye view, depicting the stage and surrounding elements as if flattened onto a single plane.
• The sectional view (or cross-section) is created by visually “cutting” the theatre space in half to reveal the interior’s vertical dimensions.

SEO Keywords: theatrical space, stage configurations, groundplan, sectional view

1.2 Theatrical Stage Nomenclature: Navigating the Landscape

Familiarize yourself with the terminology used to describe different areas of the stage. Key terms include:

• Proscenium: The architectural frame separating the stage from the house.
• Plaster Line: An imaginary line at the back of the proscenium arch, serving as a reference point.
• Centerline: An imaginary line bisecting the stage, perpendicular to the plaster line.
• Apron: The area between the plaster line and the edge of the stage.
• Orchestra Pit: The sunken area in front of the stage, often used by musicians.
• Playing Area/Performance Area: The portion of the stage visible to the audience.
• Backstage: The area behind the stage, concealed from the audience.

Light is a form of radiant energy, and it can be measured and quantified using various scientific metrics. Understanding terms like lumen, candela, footcandle, and lux will help you compare different light sources and make informed decisions about your lighting design. The electromagnetic and visible spectrums of light show the relative placement of light. In order to remember a rough sequential order of the electromagnetic spectrum, this mnemonic can be used:

• RIVUXGa (Radio waves, Infra red, Visible spectrum, Ultra violet, X-rays and Gamma rays)

SEO Keywords: lumen, candela, footcandle, lux, electromagnetic spectrum, radiant energy

Five Metrics of Light

• Luminous flux
• Illuminance (light level)
• Luminous Intensity
• Luminance (photometric brightness)
• Luminous exitance

The interrelationship of the first three metrics is expressed as a well-known formula known as the Inverse Square Law:

• Illuminance = luminous intensity divided by (distance)2.

SEO Keywords: metrics, IESNA, luminous intensity, inverse square law

3.2 Color: Adding Emotion and Depth

Color is different wavelengths of light within the visible spectrum, and it plays a crucial role in setting the mood and atmosphere of a scene.

• Hue: The quality that differentiates one color from another.
• Saturation: The amount of hue in a color mixture.
• Value: The lightness or darkness of a color.
• Tint: A color of high value, mixed with white.
• Shade: A color of low value, mixed with black.
• Tone: A color mixed with both white and black.

SEO Keywords: hue, saturation, value, tint, shade, tone, complementary colors

Color Temperature

Color temperature, specified in degrees Kelvin, is a relative measurement of different wavelengths of light.

• Household incandescent: ~2700K
• Stage lighting incandescent: ~3200K
• Metal-halide moving light: ~6000K

SEO Keywords: color temperature, degrees Kelvin

Color Mixing

• Wattage (Watts): The amount of electrical energy consumed by a device.
• Voltage (Volts): The electrical pressure that drives the current.

Two circuit types are used to distribute power from the source to the load. Parallel circuits contain two wires that run to each bulb. However, series circuits’ electricity follows a single path.

SEO Keywords: electricity, amperage, wattage, voltage, parallel circuit, series circuit

The Control Path

Electricity is supplied to a device through its own control path. The four points in the path are the device, the circuit, the source, and the control.

• Dimmer: Regulates voltage.
• Circuit: Wiring from dimmer to instrument.
• Control: Device controlling the dimmer.

SEO Keywords: control path, dimmers, circuits, control

Computer Memory Storage

Random access memory (RAM) is where information can be altered, and storage media is where information can be written. Therefore, it is critical to remember to save to storage.

Computer Lighting Console Control Philosophies

Two types of logic are used in today’s computer lighting consoles:

• Cue Only: Each memory is an individual snapshot.
• Tracking: Only channel intensities that are different are altered in each memory, and unaddressed channels “track through.”

Key differences separate the computer preset console and computer tracking console: The computer preset console individually addresses the intensity level of each channel in every memory. The computer tracking console records only channel intensities that are different from the previous memory.

SEO Keywords: cue only, tracking, computer lighting console, computer memory

4.3 Cue and Memory Nomenclature: Defining the Order

Terms like “cue”, “memory”, and “scene” are commonly used, often with varying meanings. Here is some nomenclature for reference:

• Called Cue
• Follow Cue
• Preset Cue
• Fronts Up Cue
• Fronts Out Cue
• Base Cue
• Effect Cue
• Fade to Black Cue
• Blackout
• Bow Cue
• Bow Preset Cue
• Bow Ride Cue
• Restore Cue
• Postset Cue

SEO Keywords: called cue, follow cue, preset cue, fade to black cue, restore cue, cue nomenclature

4.4 Computer Lighting Console Syntax

On many computer lighting consoles, spoken words or phrases are interpreted by a board operator and typed into a keypad to achieve the desired result. Some have typographical symbols that are adopted as shorthand for English words.

• “>” – Selection of continuous range of channels
• “@” – Activating channel intensity
• “+” – “and” or “plus”
• “−” – “minus” or “less”

4.5 Time Fades: Defining Speed

The time fade, usually shortened to “time,” is the duration of time that occurs between the moment the GO button has been pressed and the moment the fade is complete. It can be broken into two segments of speed: Up and Down. Assign a wait for the amount of time that occurs between the moment at which the GO button is pressed and when the memory actually loads into a fader. Apply a delay for the amount of time between the moment at which the GO button is pressed loading memory into a fader, and when the cue that it is linked to, then automatically loads into a fader.

4.6 Lighting Console Support Software

Software applications are used to pre-program the lighting for a production. One is the off-line editing program, and the other is the pre-visualization program.

SEO Keywords: offline editor, pre-visualization program

5. Lighting Instruments: Tools of the Trade

Selecting the proper lighting instruments is crucial. This selection begins by knowing the different characteristics of each instrument type.

5.1 Components of Lighting Instruments: What Makes It Shine?

Theatrical lighting instruments usually consist of three components contained within a housing: lamps, reflectors, and lenses.

Lamps

These are light sources used within the lighting instrument. The two main types of lamps used for modern theatrical stage lighting are incandescent and tungsten-halogen lamps. Black lights, Metal Halide (HMI), and LED are other options to consider.

Reflectors

Mirrored reflectors are used to direct the light created by the lamps toward the lens. There are four different types of reflectors most often used in theatrical lighting instruments: air, spherical, parabolic, ellipsoidal.

Lenses

These are glass surfaces used for color filters to change the properties of its light beam. The lenses are constructed from either glass or plastic to control the beam of light created by the lamp inside the housing. A convex lens cut in half results in a Plano-convex lens (“Plano” means flat). This is the basic lens configuration employed in most theatrical lighting instruments.
