A Method for Measuring the Steadiness of Motion Picture Cameras

The unsteadiness of the film motion in a motion picture camera may be directly measured in terms of the maximum failure to return frames to identical register on successive passages of the film through the camera by photographing a ruled target during each of the successive passes, and inclining the target before the second passage of the film through the camera. The amount of tilt and the line width depend on the focal length of the lens being used and the resolving power of the film.
