David Claerbout's (1969) work is a unique mixture of photography, film and painting. Originally schooled as a painter and draughtsman, Claerbout uses digital tools to alter photographs by moving shadows around, adding in walls or changing the positions of objects or figures. He makes the leaves move in an old photograph of a motionless tree, lights up the hand-held torch in a group portrait or makes a chair rock. By digitally editing old photo material, he explores the boundaries between moving and static images while playing with perception and experience of time.
