Researchers investigate some of the first color photographs ever produced Shane McGlaun - Apr 19, 2021, 5:14am CDT A group of researchers from the EPFL Audiovisual Communications Laboratory were allowed to study some of the very first color photographs ever produced. The photos are typically locked in the vaults of museums around the world and are the original photographic plates and images from scientist and inventor Gabriel Lippmann. Lippmann won the 1908 Nobel Prize in physics for his method of reproducing colors in photography. Researchers are investigating the photographs and photographic plates, saying that most photographic techniques take just three measurements for red, green, and blue. However, they have discovered that Lippmann’s approach captured 26 to 64 spectral samples of information in the visible region.
