Apparatus for Time Lapse Motion Picture Photography
With the rapidly growing importance of motion pictures as a means of disseminating information among farmers, the Office of Motion Pictures of the Department of Agriculture has for some time felt the necessity for providing means of making motion pictures of such natural processes as seed germination, mould formation, plant growth, the development of plant and tree diseases and the like-processes that are too slow to be photographed by hand cranking. Some work of this type was done by hand, using the stopmotion crank, but the obvious limitations of this method made it impracticable. The first machine, as far as this office is concerned, for doing the work automatically was built by Mr. George Georgens, in charge of the laboratory of this office. Lack of time and facilities, however, interfered with carrying this experiment to a conclusion.
