Edwin Smith's (1921-71) atmospheric landscapes and scenes of urban life illustrated the pages of prestigious mid-century publications – among them, Vogue, the Shell Guides and a series by Thames and Hudson. A committed champion of regional diversity, Smith documented Britain in a period of post-war building that threatened to homogenise. His images made fans of peers Cecil Beaton, Sir John Betjeman and Alan Bennett. The latter has contributed to a film for the exhibition. RIBA presents prints, books and photographic equipment from the 80,000-strong collection donated by Smith's widow, architectural historian Olive Cook.
