In the United States, Canada and the United Kingdom, grips are camera support equipment technicians in the filmmaking and video production industries. They constitute their own department on a film set and are directed by a key grip. Grips have two main functions: The first is to work closely with the camera department to provide camera support, especially if the camera is mounted to a dolly, crane, or in an unusual position, such as the top of a ladder. Some grips may specialize in operating camera dollies or camera cranes. The second function is to work closely with the electrical department to create lighting set-ups necessary for a shot under the direction of the director of photography. [1]
Grips' responsibility is to build and maintain all the equipment that supports cameras. This equipment, which includes tripods, dollies, tracks, jibs, cranes, and static rigs, is constructed of delicate yet heavy duty parts requiring a high level of experience to operate and move. Every scene in a feature film is shot using one or more cameras, each mounted on highly complex, extremely expensive, heavy duty equipment. Grips assemble this equipment according to meticulous specifications and push, pull, mount or hang it from a variety of settings. The equipment can be as basic as a tripod standing on a studio floor, to hazardous operations such as mounting a camera on a 100 ft crane, or hanging it from a helicopter swooping above a mountain range.

Good Grips perform a crucial role in ensuring that the artifice of film is maintained, and that camera moves are as seamless as possible. Grips are usually requested by the DoP (Director of Photography) or the camera operator. Although the work is physically demanding and the hours are long, the work can be very rewarding. Many Grips work on both commercials and features.

In the UK, Australia and most parts of Europe, grips are not involved in lighting. In the "British System", adopted throughout Europe and the Commonwealth (excluding Canada), a grip is solely responsible for camera mounting and support.
The term "grip" is derived from an older term in U.S. theatre where it designated stagehands who moved scenery. [3]
U.S. grips typically belong to the International Alliance of Theatrical Stage Employees (IATSE). Canadian grips may also belong to IATSE or to Canada's other professional trade unions including Toronto's Nabet 700, or Vancouver's ACFC. British grips usually belong to BECTU (Broadcasting Entertainment Cinematograph & Theatre Union). [4]
On all union jobs, grips do not touch the lights themselves. The placement of lighting instruments and electric power distribution is handled by the electricians who work under a gaffer. Grips handle all the non-electrical equipment that modifies the light. This work is done by setting stands that hold flags, nets, diffusing materials or other gobos that control the quality, intensity, or shape of the light.
Grips also set "passive fill" which is a term for the reflected light that is "bounced" back onto a subject on the fill or non-key light side. The first choice for most film-makers' fill is a product known in the US as beadboard [5] [6] [7] [8] [9] and called "poly", short for polystyrene, in Europe. It is rigid insulation made for the construction trade, but was adopted by the film trade because of its "true-white" color and "soft" bounce.
Grips may also be called on to set "negative fill", which is the reduction of ambient or non-directional light, such as ambient sunlight, to raise contrast on the subject. This is achieved by setting "solids", made of black fabric, either flags (up to 4' × 4') or rags (6' × 6' or larger) on the non-key light side or wherever the negative fill is desired.
When shooting day exteriors, grips perform similar functions, but with the sun as the primary light source. Grips use overhead frames up to 20' × 20' or larger for the shaping or filtering of sunlight. The lighting set-ups for these exterior shots can become quite extensive, and the use of boom lifts (called "condors") is common. Condors are especially useful at night when they are rigged to raise lights or diffusing material (up to 120 feet in the air) to create moon-effect lighting.
Grips also satisfy rigging needs on set. Examples of simple rigs include the menace arm, which allows a light to be boomed over set using one stand, or goalposts that span over top of set using two stands. More advanced rigs can include working with pulleys, steel cable or trusses. Grips also rig picture cars on process trailers, placing camera and lights around the vehicle for driving shots. This often includes the use of hood mounts, side mounts, suction cup mounts and proprietary clamps to attach film equipment to vehicles without causing damage.
Grips also do "blackouts" and "tenting-out" windows and doors. When shooting interiors day-for-night on location, grips need to eliminate all daylight entering the set. If windows or other openings are not visible in a shot, the light may be blacked out with a cloth known as duvetyne or rags, and in rare cases, plastic sheeting. When windows or doors are seen from camera, black out tents must be created outside of windows to allow lights to be placed outside, or green screens to be seen through the window, lit only by lights placed by electricians.
Grips are also responsible for safety on the set as it relates to the force of gravity. Insofar as stands, ladders, scaffolds, and overhead rigs are properly installed, grips are charged with making them safe because the other crew members must climb on, walk around, or otherwise negotiate the different grip set-ups. The key grip may even be held responsible for injuries that happen on set, especially if the injury is caused by a falling lighting instrument.
A grip uses some tools typically used by mechanics and construction workers. As in those vocations, grips need hand tools at the ready.(Tools such as ratchet straps, wedges and a normal tool box)
A film crew is a group of people, hired by a production company, for the purpose of producing a film or motion picture. The crew is distinguished from the cast, as the cast are understood to be the actors who appear in front of the camera or provide voices for characters in the film. The crew is also separate from the producers, as the producers are the ones who own a portion of either the film studio or the film's intellectual property rights. A film crew is divided into different departments, each of which specializes in a specific aspect of the production. Film crew positions have evolved over the years, spurred by technological change, but many traditional jobs date from the early 20th century and are common across jurisdictions and filmmaking cultures.
The film industry is built upon many technologies and techniques, drawing upon photography, stagecraft, music, and many other disciplines. Following is an index of specific terminology applicable thereto.
Stage lighting is the craft of lighting as it applies to the production of theater, dance, opera, and other performance arts. Several different types of stage lighting instruments are used in this discipline. In addition to basic lighting, modern stage lighting can also include special effects, such as lasers and fog machines. People who work on stage lighting are commonly referred to as lighting technicians or lighting designers.
An electrical lighting technician, or simply lighting technician, are involved with rigging stage and location sets and controlling artificial, electric lights for art and entertainment venues or in video, television, or film production.
"Below-the-line" is a term derived from the top sheet of a film budget for motion pictures, television programs, industrial films, independent films, student films and documentaries as well as commercials. The "line" in "below-the-line" refers to the separation of production costs between script and story writers, producers, directors, actors, and casting and the rest of the crew, or production team.
A key grip is a senior role on movie sets, involved with a wide variety of behind-the-scenes tasks. The key grip supervises grip crews who support camera and lighting technicians; assesses what equipment is necessary for each shooting location; coordinates the transportation of this equipment and its set up; and arranges the general movement and positioning of the camera and collaborating with the director of photography. The key grip relies on the best boy as their foreperson to supervise the grip crew.
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 gobo is an object placed inside or in front of a light source to control the shape of the emitted light and its shadow.
Television crew positions are derived from those of film crew, but with several differences.
In film production, a C-stand is primarily used to position light modifiers, such as silks, nets, or flags, in front of light sources. The stand is constructed of metal and consists of a collapsible base, two riser columns, and a baby pin on top. In addition, a C-stand typically includes a gobo head and a gobo arm, also known as a grip head and grip arm, which provide the ability to articulate a light modifier without moving the stand itself. The legs of C stands are designed to be nested, so many stands can be placed around a light source.
This article contains a list of cinematic techniques that are divided into categories and briefly described.
A stagehand is a person who works backstage or behind the scenes in theatres, film, television, or location performance. Their work include setting up the scenery, lights, sound, props, rigging, and special effects for a production.
Intelligent lighting refers to lighting that has automated or mechanical abilities beyond those of conventional, stationary illumination. Although the most advanced intelligent lights can produce extraordinarily complex effects, the intelligence lies with the human lighting designer, control system programmer, or the lighting operator, rather than the fixture itself. For this reason, intelligent lighting (ILS) is also known as automated lighting, moving lights, moving heads, or simply movers.
Stage lighting instruments 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.
In theatre, an electrician is a person who works with the various aspects of lighting. Some of the positions among electricians include the lighting supervisor, master electrician, deck electrician, light board operator, moving light programmer, followspot operator, as well as simply electricians. This group is generally known as the "Electrics" Department or LX Department.
In film and television crews, the gaffer or chief lighting technician is the head electrician, responsible for the execution of the lighting plan for a production. The gaffer's assistant is the best boy electric.
A flag is a device used in lighting for motion picture and still photography to block light. It can be used to cast a shadow, provide negative fill, or protect the lens from a flare. Its usage is generally dictated by the director of photography, but the responsibility for placing them can vary by region, usually devolving to either the gaffer and electricians or the key grip and lighting grips.

Stage lighting accessories are components manufactured for conventional (non-automated) stage lighting instruments. Most conventional fixtures are designed to accept a number of different accessories designed to assist in the modification of the output. These accessories are intended to either provide relatively common functionality not originally provided in a fixture, or to extend the versatility of a lighting instrument by introducing features. Other accessories have been designed to overcome limitations or difficulties some fixtures present in specific applications.
