    ABSTRACT: The photographic activity test (PAT) was used to quantify the effects of liglin-containing papers and boxboards on photographic image stability. For papers in direct Contact with photographs, as lignin content increased, both gelatin staining and silver image interaction increased. These effects were somewhat mitigated by the inclusion of calcium carbonate buffering in the paper. For boxboards surrounding but not in direct contact with photographs, the effects were only slightly mitigated by the air space between lignin-containing board and test detectors. It was also determined that other wood components, collectively known as extractives, were also reactive with silver images. These extractives are, however, simultaneously removed with lignin during pulp delignification.

    ABSTRACT: In the complex situation of a real archives or library, the contribution that air pollution makes to the fading of images is not easy to measure or observe. The effects are subtle and occur slowly, blending in with the action of light, heat, humidity, and the inherent stability (or instability) of each individual type of photograph. We are not able to say what percentage of the fading of a color print is due to air pollution. We know it causes some fading, but the thermal fading characteristics of color materials are probably the major factors. Because of the chemical nature of images (including in that term products commonly used in still photography, cinema, microforms, and color hard copy output from computers), it is a reasonable expectation that airborne pollutants would act to destroy them. Color images are usually comprised of organic dyes, which depend on complex structural arrangements within the dye molecule to absorb light. Disturb that precise structure at the right spot, and a yellow dye becomes colorless, or a cyan dye becomes a weak yellow. Black-and-white photographic images are comprised of metallic silver, which must first become oxidized before it can degrade; but, with silver, the response to atmospheric pollutants is complex and depends on more than just the presence of an oxidant. The subtle interactions of the component gases of air pollution are an intriguing problem and were a major focus of this research.

    ABSTRACT: Photography and motion pictures play an important role in our society as information carriers, artistic medium, and historical document, representing cultural values which have to be preserved. The emerging electronic imaging techniques help in developing new methods to accomplish this goal. The dyes of common photographic three-color materials are chemically rather unstable. Both the thermodynamic and the photochemical stability is low. As a result, millions of photographs and thousands of films deteriorate, if not preserved and stored under optimal conditions. It is of great interest to curators of museums that house photographic or cinematographic collections to simulate and visualize the fading process. A multimedia production including images and further information offers a direct and convincing way to demonstrate the different effects of various storage alternatives on dye loss. This project is an example of an interdisciplinary approach that includes photography, conservation, and computer science. The simulation program used for the creation of the faded images is based on algorithms developed for the reconstruction of faded color photographic materials.
