Digichromatography
December 8, 2006The colour photography of Sergei Mikhailovich Prokudin-Gorskii.
Born in St. Petersburg and educated as a chemist, Prokudin-Gorskii devoted his career to the advancement of photography. In the early 1900s, he developed an ingenious technique of taking colour photographs. The same object was captured in black and white on glass plate negatives, using red, green and blue filters. He then presented these images in colour in slide lectures using a light-projection system involving the same three filters.
Some early Kodachrome images of the US during the depression are here.
