Abstract

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 optical properties of Daguerreotypes to distinguish between light absorption and scattering by the daguerreian image. Combined with a digital imaging system, the technique provides an efficient tool for documenting a Daguerreotype's condition, for determining the optimal treatment exposure in different 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 different restoration treatments are presented.
