FASCINATION OF CINEMATOGRAPHY
petus in this country through the conditions arising from the great world conflict. We are just beginning to realize how dependent we have been in allowing foreign brains to solve for us the great bulk of the more complex industrial processes and the awakening finds us determined and able to take and retain the leadership in this important task.
Efficiency means the elimination of waste — one of our greatest wastes is time waste; every excess movement wastes a precious interval of time ; the cine camera has become a detective, sleuthing out the thieving excess motion which steals valuable time.
Frank Galbraith, a noted efficiency engineer, has, by the use of motion pictures, succeeded in eliminating false and useless motions to such an extent that various factory operations have been speeded up so the output has been increased as much as three and four hundred per centum. Marvelous as it may seem, the worker was able to turn out this increased amount of work with much less fatigue than when he had done a less amount under the haphazard regime.
When the motion camera is used for time studies, a splitsecond clock is generally placed in the picture and photographed at the same time, thus giving an accurate record of the time interval between each frame or picture on the celluloid tape.
Percy Haughton, the Harvard football coach, has adopted the motion camera for revealing the faulty and unnecessary motions of players on the football field. Every fraction of a second gained on the athletic field is a big boost toward victory.
A picture released about a year ago by one of the large companies excited much comment and illustrated how motion pictures may prove of great service in correcting faulty muscular action. The picture showed an athlete in various simple gymnastic feats such as walking, running, jumping and shot-putting, taken simultaneously with two cameras. One camera took the action at the ordinary rate of sixteen pictures per second, while the other camera made one hundred exposures to the second; the normal and the ultra-speed pictures were projected one after the other at the normal rate of projection thus prolonging or amplifying the ultra film to nearly six times the duration of the normal motion. It was very weird and interesting; the ease and deliberation of the prolonged action gave time for the study of every movement and the play of every muscle. One could not help
