View from the Pont Transbordeur, László Moholy-Nagy, 1929
This may well be the penultimate example of Modernism as expressed in photography in the 1920s. Moholy-Nagy climbed to the top of the Marseille transporter bridge and photographed straight down. The rhythm of the metal construction, printed dark, contrasts with the circular concrete pillar. Two triangular sails of a ship passing by prevent the photograph from turning into an entirely abstract entity.
