A major new exhibition at the Tate Modern in London examines the work of photographers William Klein and Daido Moriyama.
William Klein is one of the great American photographers of the past century, who created his own distinctive approach to street photography.
Klein often went close to his subject to ensure the viewer was aware of his presence, as opposed to the unobtrusive style practised by many.
Hired to work for Vogue by art director Alexander Lieberman, Klein often took his models out of the studio and in to public spaces.
Klein often pushed the boundaries, using extreme wide-angle lenses and even blowing up his contact sheets.
The original sheets were marked with red pencil, yet that did not stand out enough, so Klein then added enamel paint, seeing it as the creation of a new art object.
Two of Klein's best known works are Life is Good and Good for You in New York and Tokyo 1964.
Alongside the work of Klein, is that by Daido Moriyama, one of Japan's most celebrated photographers.
Moriyama's work featured in the avant-garde magazine Provoke, which ran for only three issues in the late 1960s and yet is seen as an important moment in the development of Japanese photography,
"My approach is very simple," said Moriyama, "There is no artistry, I just shoot freely. By taking photo after photo, I come closer to truth and reality at the very intersection of the fragmentary nature of the world and my own personal sense of time."
He also experimented with light and shadow, removing the subject from its surroundings.
William Klein and Daido Moriyama can be seen at Tate Modern, 10 October to 20 January 2013.
