a device for mounting a motion-picture camera during filming or a still camera during shooting or for mounting a geodetic, astronomical, or other instrument during work with such an instrument.
The most widely used type of support is the collapsible tripod, which may be made of metal or wood. A camera or instrument is attached to a tripod by means of a projecting stud, which is screwed into a threaded socket in the base of the camera or instrument. As a rule, tripods are equipped with movable heads, which make it possible to mount a camera in various positions with respect to the vertical axis. In professional motion-picture filming, panoramic heads are also used.
Portable devices are also used as camera supports (seeTRAVELING SHOTS, EOUIPMENT FOR). During filming with a handheld motion-picture camera, a gunpod, which fits into the cameraman’s shoulder, is often used.
In a number of cases, a clamp may be used as a support for a still camera. A clamp is employed to attach a camera to the back of a chair, to the edge of a table, or to some other firmly standing object.
The use of camera supports permits exposures longer than 1/30 sec.
