A light plot, lighting plot or just plot is a document like an architectural blueprint used specifically by theatrical lighting designers to illustrate and communicate the lighting design to the director, other designers and finally the Master Electrician and electrics crew. The light plot specifies how each lighting instrument should be hung, focused, colored, and connected. Typically the light plot is supplemented by other paperwork such as the channel hookup or instrument schedule.
Up until the development of computer aided drafting (CAD) programs, light plots were hand drawn or drafted on special drafting paper. Though CAD programs and hand drafting require different techniques and methods, the information is presented and used in the same way. In order to be effective a light plot must:
The plan view is the primary view of the light plot and contains the most information on the lighting instruments and their locations. As per the design definition, the plan view illustrates how the venue space would appear to someone above it. It contains the relevant architectural information of the venue space including locations of walls, the floor level, the location of seats and balconies, and occasionally sight lines, as well as the location of each lighting instrument and other relevant hardware, like modular dimmer boxes. The plan must also include information on the electrical systems of the theater--the location of outlets connected to the theater's dimmers and the available lighting positions--rails, booms, side arms, and catwalks. The plan view may also contain scenic information, such as a drawing of the set. [2]
The supplementary (and generally optional) section (side) and elevation (front) views contain much of the same information as the plan view. The section is a cutaway view of the house and stage from either the left or the right. The section line is typically the venue's center line. The elevation is a plot oriented as if viewing the stage from the audience. These supplementary views serve primarily to further illustrate relevant architectural and scenic features, including sight lines. Most commonly the section and elevation plots feature limited electrical information and are used mainly as a reference for the lighting designer or electrician to identify the purpose of each lighting fixture, especially as to how it interacts with any relevant scenic elements. The elevation and section views might also be provided to the electrics crew as a secondary reference for the positions of lighting instruments. [3]
The instrument layer contains all the information relating to the lighting instruments. This includes:
In the past when plots were completely hand drafted, a lighting designer would sometimes plot the lighting instruments on a transparent overlay which could be placed over the plan, section and/or elevation views, therefore allowing the "blank" views (containing only architectural information) to be re-used for other lighting configurations. The advent of CAD-based lighting design has made this practice obsolete, though occasionally useful.
The information contained in the lighting instruments section should follow consistent, easy to understand rules which are explained in the key, expediting the electric crew's job of hanging and focusing the fixtures. [4]
The title block contains several pieces of key information on the production including the show title, date, and venue name, as well as the names of the performance's lighting designer and director. The title block also contains the legend, which identifies all of the drafting symbols used in the plot, as well as any special notes
In addition to the light plot there are a number of other important pieces of paperwork (i.e. dimmer hookup, instrument schedule, and magic sheet) in a complete lighting design. As each part of the lighting design is relevant only to a specific group of technicians, the entire design is generally provided only to the director and master electrician.
Stage lighting is the craft of lighting as it applies to the production of theater, dance, opera, and other performance arts. Several different types of stage lighting instruments are used in this discipline. In addition to basic lighting, modern stage lighting can also include special effects, such as lasers and fog machines. People who work on stage lighting are commonly referred to as lighting technicians or lighting designers.
Technical drawing, drafting or drawing, is the act and discipline of composing drawings that visually communicate how something functions or is constructed.
In theatre, a lighting designer works with the director, choreographer, set designer, costume designer, and sound designer to create the lighting, atmosphere, and time of day for the production in response to the text while keeping in mind issues of visibility, safety, and cost. The LD also works closely with the stage manager or show control programming, if show control systems are used in that production. Outside stage lighting, the job of a lighting designer can be much more diverse, and they can be found working on rock and pop tours, corporate launches, art installations, or lighting effects at sporting events.
Stagecraft is a technical aspect of theatrical, film, and video production. It includes constructing and rigging scenery; hanging and focusing of lighting; design and procurement of costumes; make-up; stage management; audio engineering; and procurement of props. Stagecraft is distinct from the wider umbrella term of scenography. Considered a technical rather than an artistic field, it is primarily the practical implementation of a scenic designer's artistic vision.
An electrical lighting technician, or simply lighting technician, are involved with rigging stage and location sets and controlling artificial, electric lights for art and entertainment venues or in video, television, or film production.
Scenic design, also known as stage design or set design, is the creation of scenery for theatrical productions including plays and musicals. The term can also be applied to film and television productions, where it may be referred to as production design. Scenic designers create sets and scenery to support the overall artistic goals of the production. Scenic design is an aspect of scenography, which includes theatrical set design as well as light and sound.
Architectural lighting design is a field of work or study that is concerned with the design of lighting systems within the built environment, both interior and exterior. It can include manipulation and design of both daylight and electric light or both, to serve human needs.
The light board operator or moving light programmer, is the electrician who operates and/or programs the light board. Depending on the scale and type of production, the board op may be responsible for conventional or automated lighting fixtures, as well as practicals and, in some instances, controlling video as well.
In theatre, the master electrician is responsible for implementing the lighting design for a production drawn up by the lighting designer. This involves overseeing the preparation, hanging, connection and focusing of stage lighting fixtures.
A stagehand is a person who works backstage or behind the scenes in theatres, film, television, or location performance. Their work include setting up the scenery, lights, sound, props, rigging, and special effects for a production.
Stage lighting instruments are used in stage lighting to illuminate theatrical productions, concerts, and other performances taking place in live performance venues. They are also used to light television studios and sound stages.
Performing arts – are art forms where the participant engages in a physical performance using their body, voice, language, or use of specific equipment for entertainment purposes.
A theatrical technician, also known as a theatrical tech, theatre technician, or theatre tech is a person who operates technical equipment and systems in the performing arts and entertainment industry. In contrast to performers, this broad category contains all "unseen" theatrical personnel who practice stagecraft and are responsible for the logistic and production-related aspects of a performance including designers, operators, and supervisors.
In theatre, an electrician is a person who works with the various aspects of lighting. Some of the positions among electricians include the lighting supervisor, master electrician, deck electrician, light board operator, moving light programmer, followspot operator, as well as simply electricians. This group is generally known as the "Electrics" Department or LX Department.
In theatrical productions, an instrument schedule is a listing of all the lighting instruments and information about them used in a show. The instruments are organized by their position on-stage, and is the distinguishing characteristic between an instrument schedule and a channel hookup or similar paperwork. The instrument schedule includes all information about every instrument, including hanging location, instrument number, type, wattage, color, focus area, circuit, dimmer and templates, along with any additional information. The variety of information included in an instrument schedule generally makes this more "complete" than other generated paperwork, and as such the schedule is often considered the "master" sheet. The master electrician uses the information contained in the instrument schedule along with the light plot to direct the hanging of the instruments.
In theatrical productions, the channel hookup is a printout of a lighting database such as Lightwright that organizes all the lighting information for a stage show by the channel number associated with the lighting equipment and limits the information associated with a particular lighting instrument such that a designer or electrician can access needed information rapidly and efficiently.
RUCAPS was a computer aided design (CAD) system for architects, first developed during the 1970s and 1980s, and today credited as a forerunner of Building Information Modelling (BIM). It ran on minicomputers from Prime Computer and Digital Equipment Corporation (DEC).
There are different types of theatres, but they all have three major parts in common. Theatres are divided into two main sections, the house and the stage; there is also a backstage area in many theatres. The house is the seating area for guests watching a performance and the stage is where the actual performance is given. The backstage area is usually restricted to people who are producing or in the performance.
An architectural drawing or architect's drawing is a technical drawing of a building that falls within the definition of architecture. Architectural drawings are used by architects and others for a number of purposes: to develop a design idea into a coherent proposal, to communicate ideas and concepts, to convince clients of the merits of a design, to assist a building contractor to construct it based on design intent, as a record of the design and planned development, or to make a record of a building that already exists.
