This technological miracle of the 19th century is increasingly being recognised as a unique and irreplaceable asset of our international cultural heritage. The pictures presented in this virtual exhibition show us the faces, places and histories of the nineteenth century and look at the revolution made by photography in the field of visual mass communication. Its breakthrough: to satisfy our desire to record and make permanent the fleeting moments of our lives.
