Hide and Seek: Camouflage, Animal Skin and the Media of Reconnaissance investigates the scientific and media origins of strategic concealment between 1859 and 1945, from the first publication of Charles Darwin's Origin of Species to the end of the Second World War. Focusing on the Anglo-American context, Hide and Seek develops a theoretical formulation of photographic camouflage and argues that its genealogy consists of three historically and conceptually interlinking phases. Photographic camouflage was associated with an aspiration to self-erasure through material collage and was grounded in mixed-media practices of interaction with one's environment. It developed in relation to photographic documentation and reconnaissance. The first section of Hide and Seek considers the emergence of static camouflage in the domain of natural history and art-making practices—strategic concealment in relation to the instantaneous photographic image. The second section analyzes the development in World War One of serial camouflage—strategic concealment in relation to serial photography, and aerial photographic reconnaissance in particular. The third section examines the final phase, dynamic camouflage. Dynamic camouflage emerges in military training and educational films—strategic concealment of the physical human subject in relation to, and by means of an embodied projection into an all-encompassing, kinetic and multidimensional cinematic surveillance.
