He studied A level photography and then a degree in fine art in Falmouth. He started out doing documentary black and white photography, mainly of sports. He also started to experiment with subcultures in the 1980’s. Davies’ father was an abstract painter so he was always surrounded by art. His father built a dark room and studio for him and his brother and this was Marcus’ first contact with the medium. He later began to experiment with orthochromatic film, which gives images a high contrast. He was inspired to do this by Mario Jackamelly. As well as being a photographer Davies teaches photography.
