This stunning book explores what motivates artists to paint or photograph themselves, and what can be learned by looking at their self-portraits. Liz Rideal selects over 100 self-portraits from the National Portrait Gallery to examine the style, techniques and personalities of the sitters, including William Hogarth, Thomas Gainsborough, Angelica Kauffmann, John Constable, James Abbott McNeill Whistler, Cecil Beaton, Lucian Freud, David Hockney and Tracey Emin.
