Photography in the years between the First and Second World Wars fizzed with new ideas. This phase is captured in a New York exhibition, which tells this exhilarating story of avant-garde photography. More than 300 images, including from towering figures, such as Willi Ruge, Gertrud Arndt and Aleksandr Rodchenko, give an insight into the radical intentions of their creators.
• Modern Photographs from the Thomas Walther Collection, 1909 to 1949, runs at the Museum of Modern Art, New York, until April 19
