“A Dirty History of Photography is a passionate, unusual, and conceptually rich exploration of photography’s complex material histories and ties to industrial capitalism. Starting with the premise that photography is both atmospherically and environmentally sensitive, Henning weaves a complex web that connects the chemical industry, industrial pollution, and the photograph. Taking a materialist approach, she demythologizes photography, restoring it to histories of labor, extraction, and empire.”

“Film emerges here as a lively, sensitive, and sensing thing, responsive to the atmosphere and in turn generating new industrial environments—much like the humans who use the technology. Henning focuses on interwar Britain and Ilford, then expands from there, connecting to coal extraction imperialism, and beyond, demonstrating how deeply photography permeates domains of the social and industrial infrastructure, global trade, and cultural conceptions.”
