Photographic teaching apparatus utilizing a three-coordinate reference system

摘要

Apparatus for illustrating the structural and distance relationship between the subject to be photographed in a studio and the photographic equipment used. The apparatus includes a horizontal board representing the floor of the studio. A predetermined pattern of holes or apertures are located in the board beginning with a center hole and continuing with a plurality of holes forming concentric circles therearound. The distance from the center hole to each concentric circle of holes is scaled. Models representing the subject and the photographic equipment comprise a head portion to identify the model and a graduated support piece. The graduations on each support piece correspond to the scaled distances from the center hole to each of the concentric circles of holes. The models are placed at different distances and angular positions from the center hole and inserted in the concentric circle holes so that the portion remaining above the horizontal board is representative of the height of the equipment.
