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.
DMX512 is a standard for digital communication networks that are commonly used to control lighting and effects. It was originally intended as a standardized method for controlling stage lighting dimmers, which, prior to DMX512, had employed various incompatible proprietary protocols. It quickly became the primary method for linking controllers to dimmers and special effects devices such as fog machines and intelligent lights.
Public-access television is traditionally a form of non-commercial mass media where the general public can create content television programming which is narrowcast through cable television specialty channels. Public-access television was created in the United States between 1969 and 1971 by the Federal Communications Commission (FCC), under Chairman Dean Burch, based on pioneering work and advocacy of George Stoney, Red Burns, and Sidney Dean.
Dimmers are devices connected to a light fixture and used to lower the brightness of light. By changing the voltage waveform applied to the lamp, it is possible to lower the intensity of the light output. Although variable-voltage devices are used for various purposes, the term dimmer is generally reserved for those intended to control light output from resistive incandescent, halogen, and compact fluorescent lights (CFLs) and light-emitting diodes (LEDs). More specialized equipment is needed to dim fluorescent, mercury vapor, solid-state, and other arc lighting.
An emergency vehicle is a vehicle that is used by emergency services to respond to an incident. These vehicles are usually operated by designated agencies which are often part of the government, but also may be non-governmental organizations and commercial companies specifically authorised by law. Emergency vehicles may be exempted from some conventional road rules in order to reach their destinations in the fastest possible time, such as driving through an intersection when the traffic light is red, or exceeding the speed limit. In some states of the United States, however, the driver of an emergency vehicle can still be sued if the driver shows "reckless disregard for the safety of others."
A lighting control console is an electronic device used in theatrical lighting design to control multiple stage lights at once. They are used throughout the entertainment industry and are normally placed at the front of house (FOH) position or in a control booth.
Electronic programming guides (EPGs) and interactive programming guides (IPGs) are menu-based systems that provide users of television, radio and other media applications with continuously updated menus that display scheduling information for current and upcoming broadcast programming. Some guides also feature backward scrolling to promote their catch up content. They are commonly known as guides or TV guides.
Broadcast journalism is the field of news and journals which are broadcast by electronic methods instead of the older methods, such as printed newspapers and posters. It works on radio, television and the World Wide Web. Such media disperse pictures, visual text and sounds.
Tradecraft, within the intelligence community, refers to the techniques, methods and technologies used in modern espionage (spying) and generally, as part of the activity of intelligence assessment. This includes general topics or techniques, or the specific techniques of a nation or organization.
Show control is the use of automation technology to link together and operate multiple entertainment control systems in a coordinated manner. It is distinguished from an entertainment control system, which is specific to a single theatrical department, system or effect, one which coordinates elements within a single entertainment discipline such as lighting, sound, video, rigging, or pyrotechnics. A typical entertainment control system would be a lighting control console. An example of show control would be linking a video segment with a number of lighting cues, or having a sound cue trigger animatronic movements, or all of these combined. Shows with or without live actors can almost invariably incorporate entertainment control technology and usually benefit from show control to operate these subsystems independently, simultaneously, or in rapid succession.
Television crew positions are derived from those of film crew, but with several differences.
Lightwright is a proprietary software that manages theatrical lighting data and paperwork. Developed and maintained by John McKernon, the Lightwright software combines a relational database with a graphical user interface in support of user generated instrument schedules, channel hookups, and other lighting paperwork from a single spreadsheet/database. It also provides error-checking and lighting-specific data entry shortcuts. In the U.S. professional theater, Lightwright is the industry standard lighting database program. The software is widely used in the production of Broadway and other live entertainment shows, and across a number of educational and arts institutions.
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.
Party and play (PnP), also called chemsex or wired play, is the consumption of drugs to facilitate or enhance sexual activity. Sociologically, it refers to a subculture of recreational drug users who engage in high-risk sexual activities under the influence of drugs within sub-groups. This can include unprotected sex during sessions with multiple sexual partners that may continue for days.
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 fishkeeping, a refugium is an appendage to a marine, brackish, or freshwater fish tank that shares the same water supply. It is a separate sump, connected to the main show tank. It is a "refugium" in the sense that it permits organisms to be maintained that would not survive in the main system, whether food animals, anaerobic denitrifying bacteria, or photosynthesizers. For some applications water flow is limited in order to protect plants or animals that require slow flow. The refugium light cycle can be operated opposite to the main tank, in order to keep total system pH more stable (due to the uptake of acid-forming CO2 by photosynthesis occurring in the refugium during its "daylight" hours). One volume guideline for a refugium is 1:10 main tank volume.
Plans are a set of drawings or two-dimensional diagrams used to describe a place or object, or to communicate building or fabrication instructions. Usually plans are drawn or printed on paper, but they can take the form of a digital file.
Art-Net is a royalty-free communications protocol for transmitting the DMX512-A lighting control protocol and Remote Device management (RDM) protocol over the User Datagram Protocol (UDP) of the Internet protocol suite. It is used to communicate between "nodes" and a "server".
Hookup culture is one that accepts and encourages casual sex encounters, including one-night stands and other related activity, without necessarily including emotional intimacy, bonding or a committed relationship. It is generally associated with Western late adolescent sexuality and, in particular, United States college culture. The term hookup has an ambiguous definition because it can indicate kissing or any form of physical sexual activity between sexual partners. The term has been widely used in the U.S. since at least 2000. It has also been called nonrelationship sex, or sex without dating.
Media diving is underwater diving in support of the media industries, including the practice of underwater photography and underwater cinematography outside of normal recreational interests. Media diving is often carried out in support of television documentaries, such as the BBC series Planet Earth or movies, with feature films such as Titanic and The Perfect Storm featuring underwater photography or footage. Media divers are normally highly skilled camera operators who use diving as a method to reach their workplace, although some underwater photographers start as recreational divers and move on to make a living from their hobby.
