The concept for this book is simple: 500 photographers, 500 pages. Arranged alphabetically, each of the photographers--from contemporary Dutch cameraman Hans Aarsman to mid-century New York shutterbug James Van Der Zee--gets a full, oversized page. On it is a large, expertly reproduced image and a concise caption packed with information about the photographer and his or her work. The coincidental alignment of photos of different eras and aesthetic sensibilities provides unusual and exciting contrasts that add an extra dimension to readers' perception of the work. Rineke Dijkstra's color-saturated shot of a bikini-clad beachgoer in South Carolina faces a Mike Disfarmer portrait of a rural Arkansas couple in 1943. Imogen Cunningham's inimitable Nude is here, along with a more surprising image--My Mother, Bolton Abbey, Yorkshire, a color-photo collage by painter David Hockney. With iconic photographs like Alfred Eisenstaedt's shot of a sailor and a nurse kissing in Times Square on V-J Day, historic ones like Larry Burrows's shot of wounded U.S. soldiers in Vietnam, and pop images like David LaChapelle's picture of a bodybuilder posing amid a cluster of little boys aping his stance, the scope of this visual encyclopedia is truly epic. And with its incredibly low price tag, there's no better value out there for fans of photography.
