The field of view simulator includes a central portion having a viewing aperture formed therein through which the user views the subject to be photographed and a plurality of plates, each plate having a lens field of view simulation aperture formed therethrough, each of the plates being hingedly attached to the central portion to allow movement of the plates into and out of register with the viewing aperture in the central portion. Preferably, the entire simulator is fabricated as a single unit and is preferably molded of a lightweight plastic, for example, polyethylene. |
