Alison Rossiter has worked with the materials and processes of light-sensitive, gelatin silver-based photography since 1970. Her exhibition Lament pays homage to the disappearing materials of analogue photography, as the global shift from photochemical processing gives rise to digitization. Rossiter’s luminous images rely on the intrinsic qualities of expired photographic papers from throughout the 20th century that are now part of our history. Processing these papers, she reveals years of incidental exposure, moisture, humidity and physical disruption, resulting in a latent imagery that has been coaxed to life. This project would have been unimaginable just two decades ago when graded gelatin silver papers of every variety were still widely available. Transforming the medium that was once used to realistically document a fleeting moment, Rossiter abstractly depicts the passage of time.
