In October 2017, Oliver Chanarin, a photographer professor at the University of Fine Arts in Hamburg, printed an archival photograph onto cardboard in his office, and left it on display for his job share partner Adam Broomberg. The next week, his colleague printed an image on top of the photograph. This exchange happened several times, ultimately creating unprompted photomontages. “I left a sample for Adam, as a little gift,” says Chanarin, who was born in London but grew up in South Africa as a child to South African parents. “That’s how it began; as a conversation in images printed on cardboard.”
