Motion Picture in the Ariyiy — Prosser 361
speaker to challenge the present day accuracy of this statement, which has been imparted to hopeful youngsters by grim faced schoolmasters in every town and city in this country. I believe that we have discovered a key to easy instruction and a royal road to learning in the motion picture instructional film.
I will now refer briefly to a phase of the Army's problem in which this Convention, perhaps, has more interest than in others; that is, the one of proper photographic equipment for military purposes. In this connection there is an important factor to be borne in mind. The Army makes air pictures as well as ground pictures. The ground pictures are made at present by the Signal Corps, while the duty of making air pictures has been transferred from the. Signal Corps to the Air Corps.
The problem faced by the Signal Corps calls usually for the type of equipment developed by the motion picture industry for use in the production of news reel subjects. Very little Signal Corps work is performed in a studio. It is, as a rule, out of doors work. The motion picture industry, as it develops new and better types of supplies and equipment for news reels is, therefore, carrying forward the necessary research and development work required by the Signal Corps for the proper types of supplies and equipment for its peace and war time forces. We do not need special types of equipment such as are needed, for example, in the work of the Air Corps. On this branch of the Army has fallen a burden of development of special types of equipment to fit into and function satisfactorily from airplanes in flight. The Air Corps was the first in its field in this country, so originally it did not receive much help in development and research work from outside sources. Much of our Air Corps development work has been in the improvement of types of still cameras for use from airplanes. However, some attention has been given to the emplacement of motion picture cameras in airplanes. At the present time, motion picture cameras are fitted on to the machine gun racks by a special mount contrived by the Air Corps. This permits fairly free manipulation of the camera.
The problem immediately confronting our Air Corps is that of rapid development and printing in the air. The ideal is to make a picture and deliver a print upon landing. This is not difficult for still pictures and it has been done in eight minutes. Up to the present time it has not been attempted with motion pictures, al
