Have you seen a colour photograph of Gandhiji or Hitler? If you have, then it is actually a “Coloured” photograph instead of a colour. Same holds true for the pictures you have seen that of young Pele in the FIFA world cup 1958 or the early depiction of the Beatles. When did colour photography become popular despite the fact that Kodak started selling colour film in 1935? Can you imagine colour snaps with superior quality of present day digital pictures before the 1st world war?
Exactly one hundred years ago a Russian photographer named Sergey Mikhaylovich Prokudin-Gorsky, began a remarkable project with the blessing and funding of the Tsar, Nicholas II. He embarked on an extraordinary journey to capture the essence of Russian empire in full colour photographs. Many of these pictures look as if they could have been taken yesterday, with only the attire of people captured in their moment of time betraying the age of the work. Thanks to Pokrudin, we now have a record of times a century ago, so clear and vivid with remarkable colour depth. Frequent subjects among the 2,607 distinct images include people, religious architecture, historic sites, industry and agriculture, public works construction, scenes along water and railway transportation routes, and views of villages and cities. An active photographer and scientist, Prokudin undertook most of his ambitious colour documentary project from 1909 to 1915. In 1918, having lost all his money and property during the revolution, Prokudin went into exile, taking with him only his collection of nearly 2,000 glass-plate negatives and his photograph albums. The Library of Congress of USA purchased the collection from his sons in 1948.

He developed an ingenious photographic technique in order for these images to be 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. To enable this He photographed the same scene three times in a fairly rapid sequence using a red filter, a green filter and a blue filter. There was no means to develop color prints at that time, but modern technology has allowed these images to be recombined in their full original colours. Only in 2001, these glass plates could be scanned and, through an innovative process known as digichromatography, brilliant colour images have been produced after 100 years it was photographed. Because of many years of negligent storing, most of the negatives are in very poor condition, and it took hours of scrupulous work to restore their original brilliance. These pictures include the only colour photograph of Leo Tolstoy taken in 1908.
It is just the beginning of the work and hundreds of unique colour images of the past are still waiting to be returned back to life.
