In Cellulose Documents: Forget Me Not, a new purpose is given to a found archive from the 1930’s of discarded studio portrait nitrate film negatives. The crumbling and decaying negatives were preserved through digital scans and reinterpreted by the artists by combining them with microscopic imagery of botanic material. This parallels the use of cellulose in nitrate film with the makeup of organic plant cell walls. Nitrate film was used by photographers and filmmakers from the 1880s to the 1950s, but was replaced by acetate safety film after it was found to be highly flammable and unstable. By preserving these found and unidentified portraits, we illuminate the obsolete material of nitrate film through the examination of cellulose at a molecular level.
