Photography was also one of the many tools used by the artist in his work. An iconographic source for some of his series, its multiple character allowed him to reproduce the same elements and to use them in different works. For his exhibition Édifices in 1968, he presented photomontages that incorporated his architectural creations into public space. The photographic projection was introduced in the 1970s as an enlargement process to create elements such as the ‘Praticables’ for his show Coucou Bazar. Finally, the retrospective organized by Fiat in Turin in 1978 broke new ground with a spectacular mise-en-scene that included original works and light projections of other paintings, replete with a multi-projection devoted to his major work, the Closerie Falbala.
