Scientists have re-examined the creations of one of the earliest color photographers, Gabriel Lippmann, who used no pigments or dyes of any kind in his work. They sought to identify the original colors captured in Lippmann’s photographs and recreate the images using a similar process to that of the 19th-century photographer. The paper was published in the Proceedings of the National Academy of Sciences.

“These are the earliest multi-spectral light measurements on record so we wondered whether it would be possible to accurately recreate the original light of these historical scenes,” said Gilles Baechler, a software engineer at the Swiss Federal Institute of Technology in Lausanne, in an institute press release, “but the way the photographs were constructed was very particular so we were also really interested in whether we could create digital copies and understand how the technique worked.”
