Al Kodak Film is now Speed Fltm When we began the manufacture of "Speed" film it was decidedly faster than our regular N. C. emulsion. There were, however, some particulars, such as uniformity and keeping quality, in which it was more difficult to control than the old reliable "N. C." In order to protect our customers against film that might have deteriorated through age, we did not give it as long a dating as was given the N. C. film. We were inclined to make haste slowly. In the Speed film, we had just what we claimed for it: "speed". In the N. C. film, which had a very different emulsion, we had beautiful gradation and absolute reliability. Gradually, during a period of six years, we have increased the speed of our N. C. film without losing one jot of its reliability, its keeping quality or its fineness of gradation. All Kodak film is now Non-Curling Speed film, both the Auto graphic, and the "N. C." that is wound in the old way without the autographic feature. Both are the reliable, dependable film-with added speed. Important to Amateurs. Practically all negative emulsions (both plates and films) and Kodak film in particular, have a wide latitude on the side of over-exposure. This means, that while your pictures will be un satisfactory if even a little under-exposed, they can have considerably more than the necessary exposure without the slightest harm. The moral is, of course: when in doubt take the choice of erring on the side of over-exposure. Kodak Speed film will help If it isn't Eastman, out appreciably by giving better timed nega tives than can be obtained with other films .when light conditions are poor. On the other hand, the latitude is such that you can expose and should expose, under good light conditions, just the same as you always have with the regular Kodak N. C. film. It isn't intended that you should cut down exposures when using Speed film. It is intended that you shall get better negatives when working under adverse conditions-and you will. it isn't Kodak film.
