An array of documentary photographic practices that emerged during the dictatorship in Chile (1973–1990) remain understudied, despite their political, aesthetical, and historical import. From the mid-1970s onward, these different practices served different purposes: some made visible the crime of disappearance and its disavowal by the repressive state; others stood as supplementary evidence that confirmed the legal existence of the detained-disappeared; some were a crucial force in denouncing state repression and demanding justice for victims; and some made it possible for independent media to simultaneously comply with and ridicule the censorship of images imposed by the dictatorship in 1984. These practices also helped to consolidate the expanding photographic field under dictatorship. They include the public display of ID photos and portraits torn from family albums; documentary images that relatives of the victims of repression pinned to their chests; the reproduction, compilation, and incorporation of these portraits into legal files and habeas corpus claims; the publication of countless photos of popular protests in independent media; and different photographic initiatives put forward by a group of photographers who established the Independent Photographers Association in 1981. Notably, the expanding photographic field under dictatorship engaged not only individuals and groups directly involved with photography but also ad-hoc human rights collectives and organizations (especially the Group of Family Members of the Detained-Disappeared and the Vicariate of Solidarity), as well as lawyers, judges, journalists, and everyday users of photography. Given the different arenas in which documentary images circulated, the transformations they underwent to resist repression and censorship, and the array of individuals involved in their (re)production and dissemination, a study of documentary photography under dictatorship in Chile cannot content itself, as has been the case, with surveying the practices that emerged within the artistic field. A study of the visual culture under dictatorship instead reveals both the different uses of photography in the public space and the transformations of documentary images in their successive circulations and disseminations.
