Abstract Visual politics is a fast-growing field and much of it is focused on images that inspire criticism. This tendency results in a lack of attention to oppressive visual practices. A political visual literacy approaches all visual practices as being layered with different “visual truths” that were developed in response to political commitments over time. These “visual truths” inflected visual practices in ways that may outlive the political settings in which they were first articulated. Most important of these is the desire to capture human difference that framed the development of visual technologies and is still embedded in a range of visual practices. The methodology I develop here links a conjunctural analysis of visual tools and practices and the visual truths implicated in them with their operationalisation by actors as cultural tools through the framework of mediated action. I develop this approach by interrogating two layered and harmful visual practices: the White-centrism of visual technologies and the racialised origins of transphobic visualities in automatic gender recognition technology.
