Glass Plates Reborn: Digichromatography

from the author's personal collection

Russian photographer to Tsar Nicholas II, Sergei Mikhailovich Prokudin-Gorskii, captured black and white images on glass plate negatives using red, green and blue filters. He then presented the images in color using a light projection system and the same three filters. Thanks to digital technology and a process called digichromatography we are now able to view Prokudin-Gorskii's glass slides in brilliant color, the way he intended them to be. In layman's terms digichromatography involves scanning the glass negative then editing it with image editing software. Grayscale becomes RGB, layering and cropping are tackled and finally any retouching of the image is completed. That is a very brief primary explanation. Please see the full details here.
