This article investigates the paradoxical nature of cameraless photography. Born after the invention of early photography, the camera apparatus is clearly a precondition of the idea and practice of cameraless photography (photography made without a camera). Yet, at the same time, cameraless photography is situated as a form of pure photography, giving rise to the idea that the spirit of photography lies somewhere beyond the mediation of the camera. This article approaches the paradoxical nature of cameraless photography in an indirect (...) manner by considering the spectrality of photography: from conceptions of early photography as itself spectral, to the manifestation of spectres in spirit photography, to the decomposition of the spectres by X-rays and radioactivity. Cameraless photography plays a twofold role in this genealogy of photographic spectres: first, it goes against a certain understanding of the spirit of photography as conditioned by the manipulating force of the camera apparatus; second, it proves the existence of spectres by uncovering the ontological convulsions of the world.
