years by the research done by the photographic manufacturing firms, and it was in order to produce a considerable increase in the amount of this specialized photographic research work that the Eastman Kodak Company established its research labo- ratory.
The work of the laboratory deals, of course, not only with the theory of photography but with many points of practical importance both in the manufacture of photographic materials and apparatus and in their use, and the laboratory is divided into different sections corresponding to the general divisions of science, notably physics, chemistry and practical photogra- phy, the workers in these divisions collaborating in investiga- tion of the problems with which the laboratory is concerned.
The branches of science which are of chief importance in photographic problems are those of optics in physics and of the colloid, physical and organic divisions of chemistry, and Fig. 1 represents an attempt to show the relations of these branches of science to photography.
Optics deals on its geometrical side with the materials used in photography-cameras, lenses, shutters, etc.-and on its physical side with such materials as color filters and illumi- nants, but especially with the study of the relation of the pho- tographic image to the light by means of which it was prod
