For those who remember what developer trays were about—back when analog prints were mainly rendered in the darkroom (and we walked to school barefoot in the snow)—this is a mesmerizing array of photographic tools shot in loving detail. For anyone who loves great imagery, this is a who’s who of legendary names: Ansel Adams, Wynn Bullock, Lillian Bassman, Bruce Davidson, Elliott Erwitt, Emmet Gowin, and Sally Mann all have trays studied by the lens of John Cyr, who duly depicts his own. Among the surprises are variations in the trays’ wear and tear: Sylvia Plachy’s grooves are frayed; Adam Fuss’s aluminum alloy still shines. Cyr has “group shots,” too—from the photo studio at the Met, for instance. But this collection is really about individuals.
