(6) Freud is notable not only for his prodigious output - at any one time he will be at work on five or six paintings and, perhaps, an etching - but for the intense way in which he scrutinises his subjects (he is adamant that they 'affect the air around them', so his sitters must be present even when only the background is being painted).
