Light Plot
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: *Have some uniform scale (typically 1/4"=1'-0" or 1/2"=1'-0"). *Define lighting instrument information such as focus, position, color and circuiting. *Have a title block and legend contain ...

Blueprint
A blueprint is a reproduction of a technical drawing or engineering drawing using a contact print process on light-sensitive sheets. Introduced by Sir John Herschel in 1842, the process allowed rapid and accurate production of an unlimited number of copies. It was widely used for over a century for the reproduction of specification drawings used in construction and industry. The blueprint process was characterized by white lines on a blue background, a negative of the original. The process was not able to reproduce color or shades of grey. The process is now obsolete. It was first largely displaced by the diazo whiteprint process, and later by large-format xerographic photocopiers. The term ''blueprint'' continues to be used less formally to refer to any floor plan (and even less formally, any type of plan). Practicing engineers, architects, and drafters often call them "drawings", “prints”, or “plans”. It has almost entirely been replaced with digital computer-aided ...

Electrical
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of positiv ...

Instrument Schedule
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. Conventions Typically the instrument schedule is organized first by hanging location. Common hanging locati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Followspot
{{Unreferenced, date=October 2007 A spotlight (or followspot) is a powerful stage lighting instrument which projects a bright beam of light onto a performance space. Spotlights are controlled by a spotlight operator who tracks actors around the stage. Spotlights are most commonly used in concerts, musicals and large-scale presentations in which highlighting a specific mobile individual is critical. Spotlights are sometimes located overhead on catwalks. In some theatres, they may also be located in the control booth or purpose-built "spot booths" in addition to the catwalk. Spotlights may be arranged in a variety of patterns for coverage. For example, they can be located to the back or rear of a theater and aimed at the stage in front of them. This location can become problematic due to the audience being distracted by fan noise or the spot operator speaking into their headset microphone. In circus and sports, spotlights may be arranged around the facility covering both sides an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gobo (lighting)
A gobo is an object placed inside or in front of a light source to control the shape of the emitted light and its shadow. For studio photography purposes, the term "gobo" has come to refer to any device that casts a shadow, and various pieces of equipment that go in front of a light (such as a gobo arm or gobo head). In theatrical lighting, however, the term more specifically refers to a device placed in "the gate" or at the "point of focus" between the light source, called a lamp, and the lenses (or other optics). Derivation The Oxford DictionaryKelby, Scott (2006). The digital photography book : the step-by-step secrets for how to make your photos look like the pros'! First edition, p. 40. Peachpit Press, Berkeley, California. gives three definitions (and others concur): "A dark plate or screen used to shield a lens from light; (in a theatre) a partial screen used in front of a spotlight to project a shape; shield used to mask a microphone from extraneous noise."

Color Gel
Color (American English) or colour (British English) is the visual perceptual property deriving from the spectrum of light interacting with the photoreceptor cells of the eyes. Color categories and physical specifications of color are associated with objects or materials based on their physical properties such as light absorption, reflection, or emission spectra. By defining a color space, colors can be identified numerically by their coordinates. Because perception of color stems from the varying spectral sensitivity of different types of cone cells in the retina to different parts of the spectrum, colors may be defined and quantified by the degree to which they stimulate these cells. These physical or physiological quantifications of color, however, do not fully explain the psychophysical perception of color appearance. Color science includes the perception of color by the eye and brain, the origin of color in materials, color theory in art, and the physics of electr ...

Parts Of A Theater
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. Types of theatres * Arena: A large open door with seating capacity for very large groups. Seating layouts are typically similar to the theatre in the round, or proscenium (though the stage will not have a proscenium arch. In almost all cases the playing space is made of temporary staging ( risers) and is elevated a few feet higher than the first rows of audience. * Black box theatre: An unadorned space with no defined playing area. Often the seating is not fixed allowing the room to be re-configured for the demands of a specific production. Typically the seating and perfor ...

Set Construction
Set construction is the process undertaken by a construction manager to build full-scale scenery, as specified by a production designer or art director working in collaboration with the director of a production to create a set for a theatrical, film, or television production. The set designer produces a scale model, scale drawings, paint elevations (a scale painting supplied to the scenic painter of each element that requires painting), and research about props, textures, and so on. Scale drawings typically include a groundplan, elevation, and section of the complete set, as well as more detailed drawings of individual scenic elements which, in theatrical productions, may be static, flown, or built onto scenery wagons. Models and paint elevations are frequently hand-produced, though in recent years, many Production Designers and most commercial theatres have begun producing scale drawings with the aid of computer drafting programs such as AutoCAD or Vectorworks.

Catwalk (theater)
{{Unreferenced, date=June 2009 A catwalk is an elevated service platform from which many of the technical functions of a theater, such as lighting and sound, may be manipulated. Function Catwalks are used to suspend lighting instruments and microphones directed at the stage. The catwalks provide easy access for theater personnel to perform common tasks. For example, lights may need to be accessed for maintenance, position adjustment, or addition and removal of gels and gobos. Placement Typically, catwalks are located in positions hidden from audience view or directly above an audience, and are considered "behind-the-scenes". For example, many proscenium theaters have a series of two or more catwalks running parallel to the proscenium arch above a false ceiling. Stairs or a ladder up to the catwalks is usually located somewhere backstage. In modern theatres, many architects design catwalks into the "look" of the theatre. In black box theatres, catwalks and pipe grids may be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dimmers
A dimmer is a device connected to a light fixture and used to lower the brightness of the lighting, light. By changing the voltage waveform applied to the lamp, it is possible to lower the luminous intensity, intensity of the light output. Although variable-voltage devices are used for various purposes, the term ''dimmer'' is generally reserved for those intended to lighting control system, control light output from resistive incandescent light, incandescent, halogen lamp, halogen, and (more recently) compact fluorescent lamps (CFLs) and light-emitting diodes (LED lamp, LEDs). More specialized equipment is needed to dim fluorescent lamp, fluorescent, mercury-vapor lamp, mercury-vapor, solid-state lighting, solid-state, and other arc lamp, arc lighting. Dimmers range in size from small units the size of domestic light switches to high-power units used in large theatrical or architectural lighting design, architectural lighting installations. Small domestic dimmers are generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrical Outlet
AC power plugs and sockets connect electric equipment to the alternating current (AC) mains electricity power supply in buildings and at other sites. Electrical plugs and sockets differ from one another in voltage and current rating, shape, size, and connector type. Different standard systems of plugs and sockets are used around the world. Plugs and sockets for portable appliances became available in the 1880s, to replace connections to light sockets with wall-mounted outlets. A proliferation of types developed for both convenience and protection from electrical injury. Today there are about 20 types in common use around the world, and many obsolete socket types are found in older buildings. Coordination of technical standards has allowed some types of plug to be used across large regions to facilitate trade in electrical appliances, and for the convenience of travellers and consumers of imported electrical goods. Some multi-standard sockets allow use of several types of plug; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
