Camera Atomica — guest-curated by writer, curator and art historian John O'Brian — is the first substantial exhibition of nuclear photography to encompass the entire postwar period from the bombings of Hiroshima and Nagasaki in 1945 to the triple meltdown at Fukushima Daiichi in 2011.

The election of President Ronald Reagan in 1980 accompanied an intensification of the Cold War, and artists and photographers responded in large numbers to the escalating risk of a nuclear confrontation. The politics of the Cold War also coincided with a cultural debate around photography and its claims to represent what is "true" or "real." Much post-1980 nuclear photography reflects altered understandings of the limitations of photography and the dangers of the nuclear arms race.

Camera Atomica addresses pressing issues in the post-war era – nuclear weapons proliferation, toxic waste disposal and climate change – as they are represented in photography. Organized thematically, it brings together vintage and contemporary photographs, press and fine arts photographs, scientific and touristic images and advertisements and propaganda from a wide range of sources.
