iPhone photographs of commuters and midtown workers, in the long tradition of New York street and subway photography that runs from Walker Evans to Garry Winogrand, Bruce Davidson and Bruce Gilden. Voyeuristic, with the dogged diaristic sensibility of an Instagrammer, the project was born out of Arnold's popular feed: he catalogues the many characters of the city within the democratic confines of the subway and the congested midtown traffic. The colour pictures are close portraits of strangers: a mother holding a baby, an elderly man in a flat cap, a commuter in a tie.
