Besides working as a journalist, Pietro Minoli produced thousands of photographs fom the mid-1950’s onwards. As well as these pictures, the Sella Foundation conserves the lenses, cameras and the enlarger used by Pietro Minoli during his career. Also of importance are the photographs he took from helicopter and aeroplane, documenting the urban development of Biella and the Biellese. Only the prints of this series are conserved at the Foundation.
