Here are the fruits of Hockney's lifelong meditations on the problems and paradoxes of representing a three-dimensional world on a flat surface. The conversations are punctuated by wise and witty observations on numerous other artists, and enlivened by shrewd insights into the contrasting social and physical landscapes of California, where Hockney lives, and Yorkshire, his birthplace. 174 colour, 7 b/w illustrations does drawing make one 'see things clearer, and clearer, and clearer still', as Hockney suggests? What significance do different media - from a Lascaux cave wall to an iPad - have for the way we see? What is the relationship between the images we make and the reality around us? This title deals with these questions.
