Gianni Castagnoli, italian visual artist and filmmaker (Bologna 1946-2007), in his art used poor materials (paper, cardboard, wood and putty, which he uses in his paintings to represent objects). From 1969 he exhibited paintings and installations in collective and solo exhibitions. From 1972 he obtains important acknowledgments as a cinematographic author and participates with his films (including one of the most interesting results of the Italian experimental cinema, La Nott'e 'l Giorno, 1976) at international festivals. In 1979 he published 80's monographic volume, in which he collected xerochromes (a term he coined) made with color Xerox machines. Between 1982 and 1987 he collaborated, for fashion photography, with the magazine Uomo Vogue. Among the works of the 90’ the series of the Smokers and of the Horses, the large panels in relief (Dora Maar, the triptych Van Gogh) and still lifes.
