The article contains a brief history of cellulose nitrate and its use in photography, which also includes a summary of the dangers of these materials and the stages of their decomposition. The second portion of the article describes the materials used to make both prints and copy negatives from deteriorating nitrate negatives. The negatives used for this study were from a group of some 300 by the photographer, Nickolas Muray. Kodak's Panalure black and white printing paper is recommended for making copy prints. Copy negatives were made using a two-step interpositive method using Kodak's Super-XX film. Polapan Type 52 and Polacolor Type 59 (Polaroid Co.) are recommended for record photographs of negatives that cannot be copied or printed. Kodak's SO-015 Direct Duplicating Film, as is currently available, is not recommended because of its high blue sensitivity
