RT Book, Whole DB /z-wcorg/ DS http://worldcat.org ID 46785588 LA English T1 Effects of light on materials in collections : data on photoflash and related sources A1 Schaeffer, Terry T., PB Getty Conservation Institute PP Los Angeles YR 2001 SN 0892366451 9780892366453 AB This volume fills that gap by providing a survey of the impact of exposure to light with an emphasis on photoflash and reprographic sources. The information provided will assist conservators and collections managers in assessing the risk to art and archival objects of such exposures. The text surveys relevant photophysical and photochemical principles, photometric and radiometric measurement, and the spectral outputs of several light sources. Materials discussed include colorants and natural fibers; pulp, paper, and wood; natural and synthetic polymers; fluorescent whitening agents; photographic and reprographic materials; and objects containing combinations of materials. Approximations and assumptions used in the evaluation process are discussed in some detail, with examples of the different types of calculations.
