To many Westerners, Siberia remains geographically and culturally distant, a place notorious for the horror of Stalin's prison camps. Officially disbanded in 1960, the legacy of the Gulag persists, and today the camps still house a free labour force of around a million prisoners. De Keyzer photographed some 35 camps over a two year period, revealing a harsh way of life totally isolated from the rest of the world. Shaven-headed, gaunt young men crowd together to eat fish and hewn blocks of bread; a prisoner takes an icy outdoor shower in -40c conditions; another recovers from TB in a bleak ward where orange check fabric serves for both blankets and pyjamas. Alongside these images, more surprising revelations are made - a gang of brawny tattooed inmates labour under a bright blue sky; a smiling prisoner holds up his new-born baby, and female convicts smooch at the Saturday night disco. De Keyzer's images, often in startling colour, jolt us with their immediacy and offer a rare insight into the lives of those inhabiting these isolated institutions. Zona forms the second part of In From the Cold, Impressions' winter exhibition and events season.
