Tachometer
A speed measuring device, often mounted on a film camera and graduated in frames per second, so that when used with a wild motor, the actual speed of the camera is visible to the operator. Sound cameras need to run at a constant speed.
The National Film and Sound Archive of Australia acknowledges Australia’s Aboriginal and Torres Strait Islander peoples as the Traditional Custodians of the land on which we work and live and gives respect to their Elders both past and present.
