Preserving Your Collection of Film-Based Photographic Negatives

| The problem presented in the title of this paper can be addressed simply by two words: cold storage. Recent research indicates that all cellulose-based film, whether it's a cellulose nitrate negative from the 1890's or a cellulose triacetate color transparency from the 1990's, share very similar deterioration mechanisms that are temperature and humidity dependent. On balance, relative humidity has been shown to be a less serious concern at low temperatures. What this means for a collections manager is that long-term preservation of a collection of film-based negatives can be as affordable as a frost-free freezer. | ||||||||||
