Chemistry, Extraction and Sustainability

From silver salts to fog, photography’s materials remain volatile and reactive. Artforum editor Pablo Larios joins Dionne Lee, Michelle Henning, and Aspen Mays to discuss extraction, chemistry, and experimental practices shaping the medium’s material futures.
