Let’s get this out of the way first: Of the dozens of photographers not represented here that a reasonable person might expect to have been included, the most conspicuous absentees include Berenice Abbott, Ansel Adams, Robert Adams, Richard Avedon, Dawoud Bey, Henri Cartier-Bresson, Imogen Cunningham, Roy DeCarava, William Eggleston, Walker Evans, Robert Mapplethorpe, Helmut Newton and Irving Penn. Putting together a list of the 25 most significant photographs since 1955 — both fine art photos and reportage — proved a difficult task for the panelists (even the chosen time frame was controversial). They were: the Canadian conceptual photographer Stan Douglas, 63; the Vietnamese American photographer An-My Lê, 64; the acting chief curator of Photography at the Museum of Modern Art, Roxana Marcoci, 66; the American documentary photographer Susan Meiselas, 75; the American photographer Shikeith, 35; and Nadia Vellam, 51, T’s photo and video director. Each participant (including myself, the moderator, 36) submitted up to seven possible nominees for the list. We gathered at The New York Times Building on a morning last February (with Shikeith joining on video from a shoot in Los Angeles) to begin our deliberations.
