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] |
Stage Lighting Instrument
Stage lighting instruments (lanterns, or luminaires in Europe) 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. Many stagecraft terms vary between the United States and the United Kingdom. In the United States, lighting fixtures are often called "instruments" or "units". In the UK, they are called "lanterns" or "luminaires". This article mainly uses terms common to the United States. Components :''See the picture at the top of the page for the physical location of most components.'' Stage lighting instruments all have the following components: Housing The lamp housing is a metal or plastic container that serves as a body for the entire instrument and prevents light from spilling in unwanted directions. It comprises all of the exterior of the fixture except for the lens or opening. The housing may be designed with specific e ...

Super Trouper (spotlight)
Super Trouper is a registered trademark for a series of follow spotlights used in stadium, concert, and special-event lighting. The lights are manufactured by Strong Lighting of Omaha, Nebraska which acquired the Super Trouper and its larger cousin, the Gladiator, from its former manufacturer Syncrolite who had acquired them from Ballantyne Strong of Omaha, Nebraska (originally Strong Electric Corporation of Toledo, Ohio) in November 2016. History The lights were first manufactured in 1956. Initially, the Super Trouper utilized a high-intensity carbon arc lamp. In the 1980s, as carbon arc lamps fell into decreasing use, the spotlight began to employ a high-intensity xenon lamp as its light source. With very few exceptions, Strong has maintained a consistent design on Super Trouper models since the first xenon-type models were introduced in the late 1970s. Initially the reflector unit was composed of electroformed nickel with a rhodium plating. Today, Super Trouper follow spots ...

Spotlight Operator
The spotlight operator or followspot operator is a theatrical technician who operates a specialized stage lighting instrument known as a followspot. A followspot is any lighting instrument manually controlled by an operator during a performance. Generally a followspot will be a dedicated, large lighting instrument designed to pan and change size, beam width, and color easily by hand. Followspot controls *Choppers – Cuts or shutters the top and bottom part of the beam. *Douser – Controls intensity. *Iris – Controls beam size. *Trombone – Controls focal length. *Color frames – Changes the color of the light. May also known as a boomerang or a color magazine. Color magazines contain the color gels, which are counted from the rear of the follow spot forward. Cueing The way the lead follow-spotter will cue you is by saying "Spot(s) 2 (and 3) on ctor/actresss) in a frame 2 (sometimes it's more than one color at once) with a half douser." It may seem confusing at first, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lens (optics)
A lens is a transmissive optical device which focuses or disperses a light beam by means of refraction. A simple lens consists of a single piece of transparent material, while a compound lens consists of several simple lenses (''elements''), usually arranged along a common axis. Lenses are made from materials such as glass or plastic, and are ground and polished or molded to a desired shape. A lens can focus light to form an image, unlike a prism, which refracts light without focusing. Devices that similarly focus or disperse waves and radiation other than visible light are also called lenses, such as microwave lenses, electron lenses, acoustic lenses, or explosive lenses. Lenses are used in various imaging devices like telescopes, binoculars and cameras. They are also used as visual aids in glasses to correct defects of vision such as myopia and hypermetropia. History The word ''lens'' comes from '' lēns'', the Latin name of the lentil (a seed of a lentil plant), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colour 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 ...

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."

Sight (device)
A sight is an aiming device used to assist in visually aligning ranged weapons, surveying instruments or optical illumination equipments with the intended target. Sights can be a simple set or system of physical markers that have to be aligned together with the target (such as iron sights on firearms), or optical devices that allow the user to see an optically enhanced — often magnified — target image aligned in the same focus with an aiming point (e.g. telescopic sights, reflector sights and holographic sights). There are also sights that actively project an illuminated point of aim (a.k.a. "hot spot") onto the target itself so it can be observed by, such as laser sights and infrared illuminators on some night vision devices. Simple sights At its simplest, a sight typically has two components, front and rear aiming pieces that have to be lined up. Sights such as this can be found on many types of devices including weapons, surveying and measuring instruments, and nav ...

Color Magazine (lighting)
A color magazine is a fixture attached to a follow spot that places different color filters in the path of the beam. Instead of working with comparatively cumbersome gel A gel is a semi-solid that can have properties ranging from soft and weak to hard and tough. Gels are defined as a substantially dilute cross-linked system, which exhibits no flow when in the steady-state, although the liquid phase may still dif ... frames, the color magazine allows the spot operator to easily slide color frames in or out of place using a series of levers. The term boomerang is also used to describe a color magazine. Color magazines are now becoming rarer with the widespread availability of programmable-colour LED lighting.

David %26 Kim (2010-09-17 By Ian T
David (; , "beloved one") (traditional spelling), , ''Dāwūd''; grc-koi, Δαυΐδ, Dauíd; la, Davidus, David; gez , ዳዊት, ''Dawit''; xcl, Դաւիթ, ''Dawitʿ''; cu, Давíдъ, ''Davidŭ''; possibly meaning "beloved one". was, according to the Hebrew Bible, the third king of the United Kingdom of Israel. In the Books of Samuel, he is described as a young shepherd and harpist who gains fame by slaying Goliath, a champion of the Philistines, in southern Canaan. David becomes a favourite of Saul, the first king of Israel; he also forges a notably close friendship with Jonathan, a son of Saul. However, under the paranoia that David is seeking to usurp the throne, Saul attempts to kill David, forcing the latter to go into hiding and effectively operate as a fugitive for several years. After Saul and Jonathan are both killed in battle against the Philistines, a 30-year-old David is anointed king over all of Israel and Judah. Following his rise to power, Davi ...

Color Temperature
Color temperature is the color of light emitted by an idealized opaque, non-reflective body at a particular temperature measured in kelvins. The color temperature scale is used to categorize the color of light emitted by other light sources regardless of their temperature. Color temperature is a characteristic of visible light that has important applications in lighting, photography, videography, publishing, manufacturing, astrophysics, horticulture, and other fields. In practice, color temperature is meaningful only for light sources that do in fact correspond somewhat closely to the color of some black body, i.e., light in a range going from red to orange to yellow to white to bluish white; it does not make sense to speak of the color temperature of, e.g., a green or a purple light. Color temperature is conventionally expressed in kelvins, using the symbol K, a unit of measure for absolute temperature. Color temperatures over 5000 K are called "cool colors" (bluish) ...
