Visual Education and Slide-Films

The invention of flexible film and Mazda light made possible slide-films having great advantages as to convenience and cost. The necessity of a fixed series of slides introduces problems that have net yet been recognized in the production of much of the material now available, and definite principles should govern the production of slide-film sequences. — The many advantages are as yet little known. Their convenience and negligible cost make their wider use desirable. At least three machines, adapted for this kind of slide, will soon be available. — Most film stereopticon positives now used in educational work are single-frame. The double-frame positive has some inherent elements of superiority, and there is a great advantage in that equipment is available for its production by any advanced amateur. Slide-films are the least expensive and most convenient of all devices for visual teaching by light projection, and open a broad field for important development.
