Wilson's quarter century in photography : a collection of hints on practical photography which form a complete text-book of the art
Edward L. Wilson's 1887 New York photography text-book, a practical manual gathering hints drawn from his twenty-five years in the trade, written for amateur and professional photographers. The pictures are plain line diagrams: ray paths through a water-filled tank, a geometric construction of converging lines, a hinged printing frame or plate holder, and a box camera-style setup with lens rays. A designer might take the clean technical line work and the dark-ground geometric plate as models for scientific or instructional graphics.
