‘Visual turn’ scholarship in International Relations (IR) acknowledges the importance of new information and communication technology for the production and circulation of images but lacks sustained engagement with the technologies themselves and how they interact with humans in the visual production of security. This article brings the visual turn into conversation with Science and Technology Studies (STS) and mobilises Latour and Woolgar’s notion of inscription to show how the production of visual artefacts and their security effects are conditioned by human/device interaction. It advances the argument that the representational force of a visual artefact is dependent not only on the content and quality of the artefact itself, but also on the specific human/device relations that condition its production. To illustrate this, the article theorises the smartphone as an inscription device and the selfie as an inscription practice and analyses the case of Zelensky’s selfie videos from the first few days after Russia’s invasion of Ukraine. Selfies inscribe meaning to security issues by mobilising the photographic affordances of indexicality, composition, and reflection in unique ways. Specifically, they focus images on the communicative acts of their producers and play on the relationship between human and device to invoke feelings of immediacy, authenticity, and intimacy.
