In the past generation, colour in art photography has moved from being a novelty to being a default, a standard. But in actuality, colour has changed a great deal in recent years, partly through the capabilities of digital cameras, and partly through the leaps made in printing and colour publishing. Walker Evans once described colour photography as vulgar, and therefore valid “when the point of a picture is precisely its vulgarity, or its color-accident through man’s hands, not God’s.” Evans was writing in 1969, when color reproduction was still quite crude. He would change his mind if he saw how sensitive it has become The aim of this Platform series, organized by David Campany, writer, curator and artist, is to bring together younger practitioners who are at the forefront of using colour in innovative ways, older photographers whose work in colour continues to be influential.
