David Hockney, one of Britain's most successful contemporary artists, took a break from painting early in the 1980s to experiment with photography. He created Joiner photographs = montages of prints showing subjects from many different angles and at different times. Filmed at his Los Angeles home, Hockney is seen creating one of these photo-pieces, from the initial idea through to the finishing touches. He talks about his interest in photography and its effect on his paintings.
