What does the perimeter of an object reveal and what does it conceal? How accurately do the technological tools that mediate our gaze surround and measure it? The Photogrammetric Turn investigates the possibilities and material and economic implications of short-range photogrammetry today. It stems from an artistic intuition and the contemporary urgency to explore the act of capturing, of freezing. In short, to photogrammetrize our context. Through essays and three conversations, the book addresses the uses of this technique in fields as diverse as forestry, modern medicine, and the digitization of heritage and works of art. Its pages interrogate its possibilities and limitations in relation to issues such as property, colonialism, knowledge structures, extractivism, the creation of archives, biopower, conservation, sovereignty, restitution, reparation, and life and death.
