“IMAGE CAPITAL,” an exhibition organized by Estelle Blaschke and Armin Linke, opens in Essen, Germany. Arguing ‘photography is information technology,’ the show (and companion website) explores six themes: memory, access, protection, mining, imaging, and currency. Tracking the photograph across contexts including scientific imaging and archives (image: Max Planck Institute, 2018), the curators ask “when and under what circumstances did images become operational?”
