Secret knowledge : rediscovering the lost techniques of the old masters (New and expanded ed)

"Secret Knowledge" created an international sensation when it was published in 2001.

David Hockneys enthralling story of how some of the great works of Western art were created with the help of mirrors and lenses and how the optical look came to dominate painting attracted major media attention around the world and generated intense debate in the fields of science and art history.

Stunning in its presentation and wide-ranging in its implications, "Secret Knowledge" remains the art book sensation of the century.
