CHAPTER SIXTEEN NATURE STUDY AND SCIENTIFIC FILMS
One of the surprising things about amateur cinematography is the number of scientists, travellers, explorers, naturalists and students who are numbered among its devotees. Until recently the substandard camera has been of but questionable value to this class of worker, but due to certain recent developments, the substandard motion picture camera is now available for practically every known kind of scientific work.
The making of travel and exploration films is little different from the usual travel practice except in those cases where unusual conditions prevail. Where such conditions are encountered it must be evident that the cinematographer, whether amateur or professional will have to formulate his own procedure. Rather than to try to set forth individual instructions covering every such condition possible, let us at once pass to the consideration of the various classes of subjects which may be encountered.
Natural History. — One of the most widely used purposes of the motion picture in science is its use in connection with natural history, and kindred branches of research. In fact, in the case of mammals particularly, the realm of the scientist and of the sportsman overlap, but while the sportsman wants films of the sport type, the scientist will want films which depict the animal in its most natural poses and surroundings. Of course when the animal is of the nocturnal variety, a source of light must be used and this will make impossible a truly natural picture, but many animals exhibit only curiosity in the presence of a blindingglare and for this reason magnesium flares often serve both to illuminate the scene and to distract the attention of the animal from the hiding place of the camera and its operator.
