Haloid Platino, Expiration ca. 1915, Processed 2009

Alison Rossiter is an American photographer whose work interrogates the chemical and temporal properties of photographic paper itself. Working with expired and outdated photographic materials, she exposes blank sheets to light, water, and environmental conditions, allowing latent chemical reactions to emerge as abstract images over extended periods. Her practice treats the photograph as a physical object subject to decay and transformation rather than a fixed document. Born in 1953, Rossiter's investigations into materiality and process situate her within a broader postwar examination of medium specificity and the indexical nature of the photographic trace.
