“There are two important things about this show,” says Clément Chéroux, senior curator of photography at SFMOMA. “First, the quantity of work – more than 300 photographs, quite a large selection, because we were able to get support from most of the big institutions – MOMA, the Art Institute of Chicago, the Metropolitan Museum of Art, National Gallery of Canada, the Musée du Quai Branly and so on, and private collections from around the world. Second, is the fact that it is arranged thematically rather than chronologically. Usually when you look at important retrospectives they are chronological, but we organised by theme because we wanted to organise it around Evans’ passion for the vernacular. He was fascinated with vernacular culture.”
