Guy Sherwin studied painting at Chelsea School of Art in the late 1960s before becoming involved with the radical film practice of the London Film-Makers' Co-operative (now LUX) where he learnt, and then taught, the darkroom arts of printing and processing. His films explore fundamental material properties of film along with its unique capacity for recording elusive moments of light and time. Use of serial and rhythmic forms in both image and sound extend the possibilities of analogue film through installation and live performance. Recent collaborations with artist Lynn Loo include performances of Live Cinema in which multiple projectors and optical sound (sounds made from light) are accompanied by improvised music. These works have been performed in Europe, North America and South East Asia.
