Matthew "Mat" Collishaw Hon. FRPS is an English artist based in London
Collishaw's work uses photography and video. His best known work is Bullet Hole, which is a closeup photo of what appears to be a bullet hole wound in the scalp of a person's head, mounted on 15 light boxes. Collishaw took the original image from a pathology textbook that actually showed a wound caused by an ice pick. Bullet Hole was originally exhibited in Freeze, the group show organised by Damien Hirst in 1988 that launched the YBA. It is now in the collection of the Museum of Old and New Art in Hobart, Australia.
