La città dipinta di Canaletto, tra espansione dello spazio e visioni dinamiche

Through the use of current digital technologies we can reproduce, virtually, the city represented in paintings that - if they properly employ the geometric-mathematical procedures of perspective - qualify themselves as reliable documentary sources suitable for the reconstruction of urban image in a given historical period. This is the case of the city views for Venice by Canaletto: as we know from the wide literature about him, he knew the perspective rules and used the camera obscura for his paintings. However, it is interesting to note that his own works are treated as experiments to expand the space represented and in order to provide a dynamic perception - if not "filmic" -, often contradicting the canonical use of geometric-perspective systems and tools.
