  Where to Watch

Artist David Hockney discusses his theory that artists were secretly using optical devices such as mirrors and lenses in creating their work as early as the 15th century. Examples from Flemish and Italian art are studied as he examines how famous paintings have had their noted mysteries newly solved; he also makes comparisons to modern film and digital imagery.
