David Gibson, himself a street photographer for three decades, offers his own broad definition in his new book, 100 Great Street Photographs. ‘The term “street photography”,’ he writes, ‘can be applied to any photographs taken in a public space, with or without the inclusion of people, which are entirely natural, and not set up.’ He goes on to add, ‘Street photography is real, it is ordinary life made extraordinary by a great variety of photographers.’ Accordingly, his book includes a wide range of locations and subjects in its 100 images – from inner-city streets to rural and coastal scenes. Some of the shots he’s chosen are the visual puns or tricks of perspective most people associate with street photography, while others are more thought-provoking and mysterious.
