William Ruby captures what cities are like late at night, that sense of being surrounded by millions of other people but suddenly alone on dark and increasingly deserted streets. There is beauty in the late night city. The shadows are deep and can feel dangerous, but the lights are brighter in the contrast.

William has photographed the late night city all over the world. Featured here are images from London, Paris, New York, Amsterdam, Barcelona, Los Angeles, Hong Kong , Glasgow and Melbourne.
