摘要

An optical inspection technique is evaluated for documenting the overall condition and for mapping the extent of tarnish on the surface of 19th century Daguerreotypes. The technique exploits the unique properties of Daguerreotype to distinguish between light absorption and scattering by the daguerreian image. Combined with a imaging system, the technique provides an efficient tool for documenting a Daguerreotype's condition, for determining the optimal treatment exposure in differ- ent areas of the image, for monitoring the treatment progress, and for forecasting the results of natural aging or attempts at restoration. Examples of optical inspection and computer simulation of the visual appearance of a Daguerreotype versus differ- ent restoration treatment are presented.
