The photographic material of Federico Maggia is a large and heterogenous collection. The Sella Foundation preserves all the equipment and cameras used by Maggia. The phototypes are of two different kinds: the plates created in his early period of photographic activity (1912-1932) and the films, prints and contact prints of the later period (1961-1985). The subjects of the early period are mainly connected with his family, including portraits of relations and photographs of travels and holidays, particularly in the mountains. Those of the second period record Federico Maggia’s professional life, his interest in architectural details and the buildings designed by him; he travelled frequently during these years, attending international congresses about architecture. Federico Maggia was an exceptional experimental photographer whose work was reflected in his architectural style.
