Can the camera be racist? The question is explored in an exhibition that reflects on how Polaroid built an efficient tool for South Africa's apartheid regime to photograph and police black people.

The artists feel certain that the ID-2 camera and its boost button were Polaroid's answer to South Africa's very specific need. "Black skin absorbs 42% more light. The button boosts the flash exactly 42%," Broomberg explained. "It makes me believe it was designed for this purpose."

The light range was so narrow, Broomberg said, that "if you exposed film for a white kid, the black kid sitting next to him would be rendered invisible except for the whites of his eyes and teeth". It was only when Kodak's two biggest clients – the confectionary and furniture industries – complained that dark chocolate and dark furniture were losing out that it came up with a solution.
