What does the photographic image share with synthetic dyes, fertilizer, and pharmaceuticals? Inspired by the city of Basel’s position as a global center of the chemical industry, this symposium investigates photography's chemical relations, tracing the networks shaped by material resources, industrial infrastructure, and scientific expertise, as well as the ecological legacies of photographic production. The symposium will conclude with an artist talk and workshop led by photographer and researcher Alice Cazenave (Goldsmiths, University of London), an advisor to the UK-based collective Sustainable Darkroom and current Ansel Adams Fellow at the Center for Creative Photography at the University of Arizona.
