history of pictures : from the cave to the computer screen

Informed and energized by a lifetime of painting, drawing and making images with cameras, Hockney, in collaboration with the art critic Martin Gayford, explores how and why pictures have been made. What makes marks on a flat surface interesting? How do you show movement in a still picture, and how do films and television connect with old masters? What are the ways in which time and space can be condensed into a static image? What do pictures show – truth or lies? Do photographs present the world as we experience it?
