Since the 1970s, British photographer Derry Moore, who is also the 12th Earl of Drogheda, has been one of the world's most celebrated chroniclers of interiors and gardens. Some of his most iconic work has been produced for Architectural Digest over the last 30 years, as well as for The World of Interiors and other publications; and a selection of his legendary images for AD appear in the new book "AD at 100: A Century of Style." Derry and I worked together at the magazine Nest, and I was privileged to write the text for one of his books, "In House." Join us as we catch up on photography, publishing, and the pleasure of a well-lit room.
