The evidential role of matter-when media records trace evidence of violence-explored through a series of cases drawn from Kosovo, Japan, Vietnam, and elsewhere. In this book, Susan Schuppli introduces a new operative concept: material witness, an exploration of the evidential role of matter as both registering external events and exposing the practices and procedures that enable matter to bear witness. Organized in the format of a trial, Material Witness moves through a series of cases that provide insight into the ways in which materials become contested agents of dispute around which stake holders gather. These cases include an extraordinary videotape documenting the massacre at Izbica, Kosovo, used as war crimes evidence against Slobodan Milosevic; the telephonic transmission of an iconic photograph of a South Vietnamese girl fleeing an accidental napalm attack; radioactive contamination discovered in Canada's coastal waters five years after the accident at Fukushima Daiichi; and the ecological media or "disaster film" produced by the Deep Water Horizon oil spill in the Gulf of Mexico. Each highlights the degree to which a rearrangement of matter exposes the contingency of witnessing, raising questions about what can be known in relationship to that which is seen or sensed, about who or what is able to bestow meaning onto things, and about whose stories will be heeded or dismissed. An artist-researcher, Schuppli offers an analysis that merges her creative sensibility with a forensic imagination rich in technical detail. Her goal is to relink the material world and its affordances with the aesthetic, the juridical, and the political.

Wherever there have been nuclear weapons and nuclear fission, there have also been cameras. Camera Atomica explores the intimate relationship between photography and nuclear events, to uncover how the camera lens has shaped public perceptions of the atomic age and its anxieties. Photographs have a crucial place in the representation of the atomic age and its anxieties. Published in collaboration with the Art Gallery of Ontario to coincide with a major exhibition there in 2014. Camera Atomica examines narratives beyond the "technological sublime" that dominates much nuclear photography, suppressing representations of the human form in favour of representations of B-52 bombers and mushroom clouds. The book proposes that the body is the site where the social environment interacts with the so-called "atomic road": uranium mining and processing, radiation research, nuclear reactor construction and operation, and weapons testing. Cameras have both recorded and - in certain instances - provided motivation for the production of nuclear events. Their histories and technological development are intimately intertwined. All photographs, including nuclear photographs, have the capability to function affectively by working on the emotions and fascinating audiences. Through a wide range of visual documentation, Camera Atomica raises questions such as: what has the role of photography been in underwriting a public image of the bomb and nuclear energy? Has the circulation of photographic images heightened or lessened anxieties, or done both at the same time? How should the different visual protocols of photography be understood?
