Understanding colors of Dufaycolor: Can we recover them using historical colorimetric and spectral data?
This work addresses the preservation of historical photographic colors for archivists and researchers, but it appears incremental as it builds on existing historical data and tools.
The paper tackles the problem of reconstructing original colors of Dufaycolor additive color photographs by developing an open-source Color-Screen tool that incorporates historical dye measurements, aiming for accurate color recovery.
Dufaycolor, an additive color photography process produced from 1935 to the late 1950s, represents one of the most advanced iterations of this technique. This paper presents ongoing research and development of an open-source Color-Screen tool designed to reconstruct the original colors of additive color photographs. We discuss the incorporation of historical measurements of dyes used in the production of the color-screen filter (réseau) to achieve accurate color recovery.
