Joseph Furttenbach
Joseph Furttenbach the Elder (30 December 1591 – 17 January 1667) was a German architect, mathematician, engineer and diarist. Biography Joseph Furttenbach was born in Leutkirch, Germany. From 1607/08 to 1620 he stayed in Italy (especially in Milan, Genoa and Florence). There he did an apprenticeship as a merchant under the supervision of his uncles. Moreover, he studied engineering, military architecture and grew an interest in theatre and stage design while abroad. Through his travels he made detailed accounts of buildings that interested him as well as festivals, processions and dramatic performances. In three of his books he wrote expositions on scenery and lighting for the theatre. He is only second to Nicola Sabbatini as one of the most extensive accounts of backstage practices during the Renaissance. After his stay in Italy, he moved back to Germany and settled in Ulm. There, he had a successful career as an architect and universal engineer Engineers, as prac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Color Gel
A color gel or color filter ( Commonwealth spelling: colour gel or colour filter), also known as lighting gel or simply gel, is a transparent colored material that is used in theater, event production, photography, videography and cinematography to color light and for color correction. Modern gels are thin sheets of polycarbonate, polyester or other heat-resistant plastics, placed in front of a lighting fixture in the path of the beam. Gels have a limited life, especially in saturated colors (lower light transmission) and shorter wavelength (blues). The color will fade or even melt, depending upon the energy absorption of the color, and the sheet will have to be replaced. In permanent installations and some theatrical uses, colored glass filters or dichroic filters are used. The main drawbacks are additional expense and a more limited selection. History In Shakespearean-era theater, red wine was used in a glass container as a light filter. In later days, colored wa ...

Foot-candle
A foot-candle (sometimes foot candle; abbreviated fc, lm/ft2, or sometimes ft-c) is a non- SI unit of illuminance or light intensity. The foot-candle is defined as one lumen per square foot. This unit is commonly used in lighting layouts in parts of the world where United States customary units are used, mainly the United States. Nearly all of the world uses the corresponding SI derived unit lux, defined as one lumen per square meter. The foot-candle is defined as the illuminance of the inside surface of a one-foot-radius sphere with a point source of one candela at its center. Alternatively, it can be defined as the illuminance of one lumen on a one- square foot surface with a uniform distribution. Given the relation between candela and lumen, the two definitions listed are identical, with the second one potentially being easier to relate to in some everyday situations. One foot-candle is equal to approximately 10.764 lux. In many practical applications, as when measurin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lumen (unit)
The lumen (symbol: lm) is the SI unit of luminous flux, which quantifies the perceived power of visible light emitted by a source. Luminous flux differs from power (radiant flux), which encompasses all electromagnetic waves emitted, including non-visible ones such as thermal radiation (infrared). By contrast, luminous flux is weighted according to a model (a " luminosity function") of the human eye's sensitivity to various wavelengths; this weighting is standardized by the CIE and ISO. The lumen is defined as equivalent to one candela-steradian (symbol cd·sr): : 1 lm = 1 cd·sr. A full sphere has a solid angle of 4π steradians (≈ 12.56637 sr), so an isotropic light source (that uniformly radiates in all directions) with a luminous intensity of one candela has a total luminous flux of :. One lux is one lumen per square metre. Explanation If a light source emits one candela of luminous intensity uniformly across a solid angle of one steradian, the total luminous flux e ...

Valve Oct
A valve is a device or natural object that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or Slurry, slurries) by opening, closing, or partially obstructing various passageways. Valves are technically Piping and plumbing fitting, fittings, but are usually discussed as a separate category. In an open valve, fluid flows in a direction from higher pressure to lower pressure. The word is derived from the Latin ''valva'', the moving part of a door, in turn from ''volvere'', to turn, roll. The simplest, and very ancient, valve is simply a freely hinged flap which swings down to obstruct fluid (gas or liquid) flow in one direction, but is pushed up by the flow itself when the flow is moving in the opposite direction. This is called a check valve, as it prevents or "checks" the flow in one direction. Modern control valves may regulate pressure or Fluid dynamics, flow downstream and operate on sophisticated Automation#Industrial automation, automat ...

Rave
A rave (from the verb: '' to rave'') is a dance party at a warehouse, club, or other public or private venue, typically featuring performances by DJs playing electronic dance music. The style is most associated with the early 1990s dance music scene when DJs played at illegal events in musical styles dominated by electronic dance music from a wide range of sub-genres, including drum and bass, dubstep, trap, break, happy hardcore, trance, techno, hardcore, house, and alternative dance. Occasionally live musicians have been known to perform at raves, in addition to other types of performance artists such as go-go dancers and fire dancers. The music is amplified with a large, powerful sound reinforcement system, typically with large subwoofers to produce a deep bass sound. The music is often accompanied by laser light shows, projected coloured images, visual effects and fog machines. Fuelled by the emerging dance scene, and spearheaded by acid house music and undergro ... [...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.Kelby, 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. 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 exact derivation of the term ''gobo'' is unclear, although it appears to have originated in cinema studios in the 1930s. It may be an American slang abbreviation of "go-between", or "go-before" (just as New York's "SoHo" signifies the area "South of Houston St ...

Limelight
Limelight (also known as Drummond light or calcium light)James R. Smith (2004). ''San Francisco's Lost Landmarks'', Quill Driver Books. is a non-electric type of stage lighting that was once used in theatres and music halls. An intense illumination is created when a flame fed by oxygen and hydrogen is directed at a cylinder of quicklime (calcium oxide), due to a combination of incandescence and candoluminescence. Although it has long since been replaced by electric lighting, the term has nonetheless survived, as someone in the public eye is still said to be "in the limelight". The actual lamps are called "limes", a term which has been transferred to electrical equivalents. History Discovery and invention The limelight effect was discovered in the 1820s by Goldsworthy Gurney, based on his work with the "oxy-hydrogen blowpipe", credit for which is normally given to Robert Hare. In 1825, a Scottish engineer, Thomas Drummond (1797–1840), saw a demonstration of the effect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
