Starting from found thermal camera recordings, the filmmaker and artist Stefan Kruse (b. 1987) made his experimental, essayistic documentary film A Lack of Clarity (2020). This book, titled after the film, transposes Kruse's dream-like documentary from screen to page. The resequencing of film stills and subtitles presents an alternate view into the social control mechanisms and evolving digital technologies that face an expanding field of what is visible (and controllable) in the contemporary city. A Lack of Clarity, designed and edited in close collaboration with Kruse, includes 200+ stills from the film, as well as essays by Volker Pantenburg and Rémi Lauvin.
