Rigging
Grips also satisfy rigging needs on set. Examples of a simple rigs include the menace arm, which allows a light to be boomed over set using one stand, or a goalposts that span over top of set using two stands. More advanced rigs can include working with pulleys, steel cable or trusses. Grips are also called on to rig picture cars on process trailers, placing camera and lights all around the vehicle for driving shots. This often includes the use of hood mounts, side mounts, suction cup mounts and other proprietary clamps to attach film equipment to vehicles, without causing damage to the vehicle.
Grips are also called on for "blackouts" and "tenting-out" windows and doors. When shooting interiors day-for-night on location, grips need to cut all the daylight entering onto set. If windows or other openings are not visible in shot, the light may be simply blacked out with a cloth known as duvetyne or rags, and in rare cases, plastic sheeting. However, 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.
