A Kodak Lesson from Motion Pictures. The exactions of the motion picture film business are un equaled in any other department of photography and, we believe, in any other line of manufacturing on a large scale. The maker of motion pictures requires high speed in the emulsion, for every exposure is necessarily a snap shot and must often be made under poor light conditions. He requires absolute dependability in the product, for he frequently spends thousands of dollars to produce his picture play, and a failure to get good negatives would mean not merely the waste of a few hundred feet of film, but the loss of the thousands of dollars spent for special trains, and actors, and settings, and the weeks, perhaps months of time, spent in preparation. The motion picture man must have a film that is free from the minutest blemish. The picture that you see upon the curtain, say 15 x 20 feet in size, is approximately seventy thousand times as large as the tiny film upon which it was made. A spot the size of a pin head upon that film would show as large as your hat upon the curtain. The requirements then, are extreme speed, fineness of grain, absolute freedom from mechanical defects and de pendability. The price of the film is a secondary considera tion. First of all, it must be right. The competition for this business is purely a competion of quality and reliability. Ninety-five per cent. of the motion picture film used in America, and at least eighty per cent. of the motion picture film used the world over is KODAK FILM. Those very qualities of speed, mechanical perfection and dependability which make Kodak Film essential to the maker of motion pictures, make it best for your use. Then too, Kodak Film is properly orthochromatic (gives the most practical rendering of color values), is absolutely protected by duplex paper from the offsetting of numbers, and is superior in keeping quality. Be sure that it is Kodak Film with which you load your Kodak, taking epecial care when traveling that no substitution is practiced at your expense. Look for "Kodak" on the spool end and "N. C." on the box. If it isn't Eastman, it isn't Kodak film. EASTMAN KODAK CO., ROCHESTER, N. Y., TheKodak City. "Geographic readers may depend upon the integrity of our advertisers."
