In the winter 2013 issue of Aperture, titled "Photography as you don't know it," leading curators, historians, writers, and publishers introduce ten photographers they believe have been overlooked or are undervalued, and deserve more attention today. Why are some figures remembered and others forgotten? In the Pictures section, Paul Trevor is introduced by Chris Boot; Seichi Furuya by David Strettell; Maria Sewcz by Britt Salvesen; Len Lye by Geoffrey Batchen; Ken Pate by Carole Naggar; Marianne Wex by David Campany; Ricardo Rangel by Bronwyn Law-Viljoen; Horacio Coppola by Sarah Hermanson Meister; and Rosangela Renno by Thyago Nogueria. In the Words section, Joel Smith considers the ever-expanding domain of photography history; Katrina Sluis speaks with Christiane Paul and Julian Stallabrass about how new technologies may shape future histories of photography; Brian Dillon considers London's Archive of Modern Conflict; Philip Gefter interviews Quentin Bajac, MoMA's new head of photography; and four writers reflect on exhibitions due for reconsideration. The issue kicked up many names new to us and to our readers, underscoring how many stories of photography are just beginning to be told.
