duced. If the subject has been produced somewhere else, professionally, it would be better and cheaper to purchase a print of that subject. The next problem is to determine whether or not the various scenes required for the production are accessible to the camera. The subject should have a real purpose and that purpose should be defined clearly before production is started.
Preparation of Outline or Scenario. A plan of production is essential. Film will be wasted if scenes are shot without relation to the plan of the picture, and additional time will be required to fit these random shots into the production. After selecting the subject, therefore, the next step is that of outlining, definitely, the content of the picture. Scenes should be selected in view of their relation to the purpose of the production.
The scenario for a motion picture, like the outline for a magazine story, should be directed at a specific audience. If the film is to tell a story to a scientific group, the film language should be thoroughly scientific. If it is intended for a juvenile group, care should be exercised to keep the point of the story within the understanding of juveniles. Once the required scenes have been determined, these should be arranged in logical sequence, and the script considered as a whole. If it is then found to be satisfactory, the plan can be turned over to the photographer for the shooting of the picture.
Selecting a Suitable Camera. The choice of a camera for this type of production will be determined by the material to be produced. If all the material planned is to be photographed in normal action, almost any of the inexpensive motion-picture cameras will be satisfactory. As variations become necessary, the need for care in selecting the equipment is increased. If slow-motion pictures are contemplated, a camera with variable speeds is essential. If nature-study subjects are to be photographed at long range, lenses of different focal lengths will be needed. If interior pictures are to be taken, it may be necessary to use lenses with greater speed than ordinary lenses, and sometimes wide-angle lenses will be required.
Good cameras range in price from $60 upward, with the average allpurpose camera ranging in price from $150 to $400 with a fair assortment of lenses and accessories. The firms which are listed on page 221 are producers of 16 mm. motion-picture cameras and can offer suggestions as to most desirable equipment for specific requirements. As with the projectors, it will be well to give comparative attention to selection.
