Shaky camera, shaky cam, jerky camera, queasy cam, run-and-gun or free camera is a cinematographic technique where stable-image techniques are purposely dispensed with. It is a hand-held camera, or given the appearance of being hand held, and in many cases shots are limited to what one photographer could have accomplished with one camera. Shaky cam is often employed to give a film sequence an ad hoc, electronic news-gathering, or documentary film feel. It suggests unprepared, unrehearsed filming of reality, and can provide a sense of dynamics, immersion, instability or nervousness. The technique can be used to give a pseudo-documentary or cinéma vérité appearance to a film.
