This encyclopaedia entry defines ‘analog(ue) photography’ as a construct of the digital age. After first situating the concept’s history in relation to that of the larger field of ‘the analog’, thereby exposing its connection to the American field of cybernetics, the entry describes how analog photography’s identity as a synonym for film was initially constructed and has subsequently evolved. Then it elaborates on the category’s formulation as a site of resistance to emerging technologies. Analog photography’s ongoing usage, the entry suggests, is a testament to the way that information-age epistemologies have organized the shape and scope of the photographic field.
