Eadweard Muybridge's Pacific Coast photographs provide an important site for investigating Victorian visual practices of the “wide.” They do not simply expand a referential frame to encompass novel subjects; they also, and more critically, register powerful narratives of temporality and modernity. This essay's analysis of the “wide” as an incipient concept of critical spatiality is not set against the more familiar temporal dimension of the long nineteenth century (a false and ultimately unproductive opposition). Rather, it places these two concerns in some tension with each other, though the argument is less about periodicity than about the representation of timescales in nineteenth-century media. In Muybridge's photographs, thinking about the representational possibilities of width is impossible without also confronting temporality. The Pacific Coast photographs are important both as explorations of timescales and artifacts in an influential nineteenth-century medium and prompts to reconsider the politico-economic networks that were central to the progress of expeditionary photography itself.
