NO CONTRAST
GOOD CONTRASTS
EXTREME CONTRASTS
OIGHLIGHTS and contrasts are important fundamentals of cinematography. Every cinematographer knows the principles of producing them. He knows that highlights are reflected images of the light source; that the location of a highlight depends upon the relative positions of camera, subject and source; that the size of a highlight is governed by the size of the light source, its distance and by the character of the surface it strikes.
He knows, too, that by the creation of contrasts with highlights, shadows and general light, he can not only give form and texture, but can control expression; and practical training has made him familiar with
infinite refinements of these principles. General Electric's engineers and research men have had to learn these facts and study them, so that they might be of greater service to the motion picture industry ... in developing new lamps and in guiding you to greater use of the many Edison MAZDAlamps alreadydeveloped.
Studios have shown their appreciation of the dependable lighting this service helps produce by using Edison Mazda lamps for all their needs from set lighting to special process work. General Electric Co., Nela Park, Cleveland, Ohio.
