Abstract

The photography system uses the principle of inverse return of light. It uses the photographic chamber as a projector. The projected surface contains all the data necessary for reproduction. The system has a housing forming a chassis at the front of which is fixed a translucid reference plate. A back forms a reflector and supports a table of printed coefficients. To the chassis is added an independent reference card designed to work in conjunction with the translucid reference plate and with the table of printed coefficients. A luminous frame is located in an emplacement designed to receive the photographic frame. Its dimensions and shape are such that free movement of the back of the chamber is not hindered. The lighting system is designed to illuminate the translucid reference plate.
