Susanne Kriemann: In the Sun's Fever Flutter Butterflies in the Stomach

When the floor of Susanne Kriemann's new Berlin studio came up, the room filled with slag. Her Geiger counter found nothing, but the slag smelled of horse, with horseshoes and buckles in it. That slag is now pigment for screen prints on paper made from the floorboards' shavings, and the old spruce boards are part of the set.

The core is Pechblende (Fever), made without a camera: uranium ore laid on dried plants from remediated Saxon and Thuringian mining heaps on sheet film for at least 14 days. You walk into rooms hung with a few large, dark, veined prints, and Kriemann says at first you won't know what you're looking at. Film photographers who beg for a hand check at BER are guarding against exactly this; she invites it.
