The work of Martin Parr bridges the divide between art and documentary photography. His studies of the idiosyncrasies of mass culture and consumerism around the world, his innovative imagery and his prolific output have placed him firmly at the forefront of contemporary art. His recent publications include Luxury (2008) and Life Is a Beach (2012). A member of the international photo agency Magnum, Parr is an avid collector of books and a world authority on the photobook.

Gerry Badger is a photo historian, architect and critic. He regularly writes and lectures on photography and has curated a number of exhibitions. His published books include Collecting Photography (2003) and monographs on John Gossage and Stephen Shore, as well as Phaidon’s 55s on Chris Killip (2001) and Eugene Atget (2001). In 2007 he published The Genius of Photography, the book of the BBC television series of the same name, and in 2010 The Pleasures of Good Photographs, an anthology of essays that was awarded the 2011 Infinity Writers' Award from the International Center of Photography, New York.
