A Spectral Approach to Digitally Restore a Faded Agfacolor Print from 1945


Trumpy, Giorgio; Chatterjee, Sreya (2022). A Spectral Approach to Digitally Restore a Faded Agfacolor Print from 1945. Archiving Conference, 19(1):101-105.

Abstract

The negative-positive chromogenic process, despite being an important milestone in the evolution of color motion picture film technology, exhibits significant fading of its image dyes, leading to the loss of chromatic integrity. A complete spectral approach for the digital restoration of chromogenic film is proposed. A material- based image processing method allows to extract the residual color information associated with the analytical densities, selectively enhance the faded dyes, and finally recreate the original aesthetics by associating the spectral properties of the film stock.
