Colour Chemigrams

This paper describes an original colour chemigram technique utilizing couplers incorporated in fully processed traditional colour photographic materials through reaction with selectively oxidized colour developing agents. Because this process bypasses light-sensitive silver halides, image structure is essentially molecular in scale and the procedure is performed under normal room illumination. Images of remarkable beauty have been produced from discarded colour films and papers. Notionally the term "chromagram" is proposed for this procedure.
