This has a public domain tag relating to works in the former soviet union. Taken in 1915, this picture was taken before the soviet union existed - is the reasoning behind its public domain status still correct? 82.13.83.244 20:39, 9 July 2007 (UTC)[reply]

Need documentation to see how this color photograph was taken in 1915.

While colorization existed in 1915, most film was not sensitive enough to take an exposure facing directly into the sun in 1915, thus the appearance of white skies in old black and white photos, even on sunny days. Additionally, how was this photo taken in color in 1915, decades before color film came into white use? This picture is suspiciously mislabeled. —Preceding unsigned comment added by Sibasimon (talk • contribs) 13:28, 23 October 2010 (UTC)[reply]

Please see Sergey Prokudin-Gorsky for a full explanation, but the short version is: he took three separate photos with red, green and blue filters, then combined them via projection to make the colors. howcheng {chat} 20:56, 23 October 2010 (UTC)[reply]
