During the 1970s photographer Kohei Yoshiyuki prowled the parks of Tokyo at night armed with a 35mm camera, infrared film and flash. His images reveal the hidden Tokyo, couples and groups freed from the constraints of life by the blanket cover of night. Clandestine trysts, onlookers hiding in bushes and those moved to participate are captured by his camera. The Park is on show at the Yossi Milo Gallery, New York until October 20 2007
