Photography of the human larynx has for a long time absorbed the interest of physicians in general and of otolaryngologists in particular. This interest is justified by the accuracy and faithfulness with which an image of an object can be reproduced, the human error in evaluating one's observations by drawings or descriptions thus being eliminated.
Unfortunately, because of the anatomic location of the larynx, photography of this structure has encountered many difficulties. The outstanding problem in the past, for both still and motion picture photography, has been to find a means of proper illumination. A great deal of this difficulty has been overcome today by the remarkable improvement and refinement in the construction of cameras with "faster" lenses and the perfection of new, highly sensitized types of film. These remarkable advances in the field of photography have been a source of renewed interest among laryngologists in this sphere of endeavor,
