Description: The principle of photographically recording work routines on a slow film (200 ASA or lower) by time exposure was developed over fifty years ago by Frank B. and Lillian Gilbreth (1) the pioneers of Method Study. They developed the idea of attaching small electric light bulbs to moving parts or body members so that a trace of light on a photographic plate could be obtained. An elaboration of this is to flash the lights off and on about ten times per second, so that an interrupted trail of light is produced. The interruptions of the light source enable it to be interpreted in terms of distance, direction, acceleration, and velocity with considerable accuracy. The basic technique has been de scribed in most texts on Industrial Engineering (2) (3) (4). The use of a Polaroid camera was suggested by Nadler (5) for general method study application. It can now be extended to chronocyclegraphy using the newer slow types of film. The main advantage of the Polaroid camera is that the operative and the engineer can see the photograph while the method is still fresh in their minds. This considerably aids their interpretations of the photo graph. The purpose of this paper is to draw attention to the simplicity and speed of the techniques and to its relatively low costs.
