Correction is a six-channel video installation which includes several hundred portraits of prisoners and prison guards filmed at correctional institutions in the U.S. In the work Tan portrays a cross-section of inmates and guards. The work employs a sub-genre in portraiture called ‘Amerikanisch’ (medium-portrait) shot in film, revealing Tan’s interest in incorporating sociological and anthropological principles into the relationship between the still and moving image. All the people portrayed stand stationary, taking our measure as much as the viewer is taking theirs. Displayed on six flat-panel screens, arranged in a circle, the configuration of the work is a deliberate reference to the panopticon, a prison plan designed by the utopian philosopher Jeremy Bentham as a way to centralize the surveillance of prisoners. On speakers one hears the live sound recorded in the prisons whilst filming.
