This volume has been written with the express purpose of assisting the amateur — the term is used in its broadest sense as a distinction from the salaried, attached professional worker — who is attracted towards cinematography. It is not a technical treatise, but is written in such a manner as to enable the tyro to grasp the fundamental principles of the art, and the apparatus employed in its many varied applications. While it is assumed that the reader has practised ordinary snap-shot and still-life work, and thus is familiar with the elements of photo graphy, yet the subject is set forth in such a manner as to enable one who never has attempted photography to take moving-pictures.
