Gaffer Tape
Gaffer tape (also known as gaffer's tape, gaff tape or gaffa tape as well as spike tape for narrow, colored gaffer tape) is a heavy cotton cloth pressure-sensitive tape with strong adhesive and tensile properties. It is widely used in theatre, photography, film, radio and television production, and industrial staging work. While sometimes confused with duct tape, gaffer tape differs in the composition of both the backing, which is made from fabric as opposed to vinyl or other plastics, and the adhesive, which is more resistant to heat and more easily removed without damaging the surface to which it adhered. History The precise origin of the name is unknown, one theory being that it is named for the gaffer (chief lighting technician) on a film crew. When cables are taped down on a stage or other surface, either to prevent tripping hazards or conceal them from view of the audience or camera, they are said to be ''gaffed'' or ''gaffered''. Gaffer tape was invented in 1959 by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Gaffer Tape
Black is a color which results from the absence or complete Absorption (electromagnetic radiation), absorption of visible spectrum, visible light. It is an achromatic color, without hue, like white and grey. It is often used symbolically or figurative language, figuratively to represent darkness. Black and white have often been used to describe opposites such as good and evil, the Dark Ages (historiography), Dark Ages versus Age of Enlightenment, and night versus day. Since the Middle Ages, black has been the symbolic color of solemnity and authority, and for this reason it is still commonly worn by judges and magistrates. Black was one of the first colors used by artists in Neolithic cave paintings. It was used in ancient Egypt and Greece as the color of the underworld. In the Roman Empire, it became the color of mourning, and over the centuries it was frequently associated with death, evil, Witchcraft, witches, and Magic (supernatural), magic. In the 14th century, it was worn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluorescent
Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence. In most cases, the emitted light has a longer wavelength, and therefore a lower photon energy, than the absorbed radiation. A perceptible example of fluorescence occurs when the absorbed radiation is in the ultraviolet region of the electromagnetic spectrum (invisible to the human eye), while the emitted light is in the visible region; this gives the fluorescent substance a distinct color that can only be seen when the substance has been exposed to UV light. Fluorescent materials cease to glow nearly immediately when the radiation source stops, unlike phosphorescent materials, which continue to emit light for some time after. Fluorescence has many practical applications, including mineralogy, gemology, medicine, chemical sensors (fluorescence spectroscopy), fluorescent labelling, dyes, biological detectors, cosmic-ray detection, vacuu ...

Dolly Grip
In cinematography, the dolly grip is a dedicated technician trained to operate the camera dolly. This technician places, levels, and moves the dolly track, then pushes and pulls the dolly and usually a camera operator and camera assistant as riders. If the dolly has a moveable vertical axis, such as a hydraulic arm, then the dolly grip also operates the "boom". If both axes are used simultaneously, this type of dolly shot is known as a compound move. A dolly grip must work closely with the camera crew to perfect these complex movements (cinematic techniques) during rehearsals. Focusing the lens is critical to capturing a sharp image, so a dolly grip must hit his or her marks in concert with a camera assistant who pulls focus. It is a skill that experience can hone to a point, but the best dolly grips are known for their "touch," and that makes them highly sought-after. A dolly grip is also employed when the camera is operated in handheld mode (on the operator's shoulders or lit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Best Boy
In a film crew there are two kinds of best boy: best boy electric and best boy grip. They are assistants to their department heads, the gaffer (in charge of electricals) and the key grip (lighting and rigging), respectively. In short, the best boy acts as the foreman for the department. A woman who performs these duties may be called best girl. Job responsibilities Best boys are responsible for the day-to-day operation of the lighting or grip department. Their many responsibilities include the hiring, scheduling, and management of crew; the renting, ordering, inventory, and returning of equipment; workplace safety and maintaining discipline within their department; completing timecards and other paperwork; stocking of expendables; loading and unloading production trucks; planning and implementing the lighting or rigging of locations and/or sound stages; coordinating with rigging crews and additional photography units (if applicable); handling relations with the other production ...

Light Board Operator
The light board operator (commonly referred to as the "Light Op" or "Board Op") 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. Sometimes, most commonly in small productions, the light board operator will also be the stage manager. Another variation in smaller productions has the responsibilities of light board operator and sound operator combined into one position. In the smallest productions, all three of these functions are done by one person. For productions where lighting and sound are operated by a single person, as well productions where sound needs to be exactly timed with lighting, it is not unusual to use MIDI Show Control (MSC), Open Sound Control (OSC), or Timecode (SMPTE Time Code) to synchronize the lighting, video, and aud ...

Live Sound Mixing
Live sound mixing is the blending of multiple sound sources by an audio engineer using a mixing console or software. Sounds that are mixed include those from instruments and voices which are picked up by microphones (for drum kit, lead vocals and acoustic instruments like piano or saxophone and pickups for instruments such as electric bass) and pre-recorded material, such as songs on CD or a digital audio player. Individual sources are typically equalised to adjust the bass and treble response and routed to effect processors to ultimately be amplified and reproduced via a loudspeaker system. The live sound engineer listens and balances the various audio sources in a way that best suits the needs of the event. Equipment Audio equipment is usually connected together in a sequence known as the signal chain. In live sound situations, this consists of input transducers like microphones, pickups, and DI boxes. These devices are connected, often via multicore cable, to individual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spike Tape
In stagecraft, a spike is a marking, usually made with a piece of tape (although some theatres use paint pens), put on or around the stage. This marking is used to show the correct position for set pieces, furniture, actors and other items which move during the course of a performance and are required to stop or be placed in a specific location. Several companies make rolls of very thin gaffer's or paper tape marketed as "spike tape" specifically for placing spikes. In a pinch, gaffer, masking or electrical tape can be used. When used to indicate locations under dark conditions, phosphorescent tape (sometimes referred to as "glow tape") is used for practical and safety reasons. Performer spikes are generally only used when positioning needs to be precise, either for safety or performance reasons, such as lighting specials. Placement During a theatrical technical rehearsal one of the stage management team will be ready to mark positions as required. To enable spike placeme ...

Theatrical Property
A prop, formally known as (theatrical) property, is an object used on stage or screen by actors during a performance or screen production. In practical terms, a prop is considered to be anything movable or portable on a stage or a set, distinct from the actors, scenery, costumes, and electrical equipment. Term The earliest known use of the term "properties" in English to refer to stage accessories is in the 1425 CE morality play, ''The Castle of Perseverance ''The Castle of Perseverance'' is a c. 15th-century morality play and the earliest known full-length (3,649 lines) vernacular play in existence. Along with ''Mankind'' and ''Wisdom'', ''The Castle of Perseverance'' is preserved in the Macro Manus ...''. The ''Oxford English Dictionary'' finds the first usage of "props" in 1841, while the singular form of "prop" appeared in 1911. During the Renaissance in Europe, small acting troupes functioned as cooperatives, pooling resources and dividing any income. Many performers p ...

Ad Hoc
Ad hoc is a Latin phrase meaning literally 'to this'. In English, it typically signifies a solution for a specific purpose, problem, or task rather than a generalized solution adaptable to collateral instances. (Compare with ''a priori''.) Common examples are ad hoc committees and commissions created at the national or international level for a specific task. In other fields, the term could refer to, for example, a military unit created under special circumstances (see '' task force''), a handcrafted network protocol (e.g., ad hoc network), a temporary banding together of geographically-linked franchise locations (of a given national brand) to issue advertising coupons, or a purpose-specific equation. Ad hoc can also be an adjective describing the temporary, provisional, or improvised methods to deal with a particular problem, the tendency of which has given rise to the noun ''adhocism''. Styling Style guides disagree on whether Latin phrases like ad hoc should be italicized. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
