For those interested in the history of color image technology a visit to this site at the Library of Congress may be of interest.

The online exhibit is of color photographs of Tsarist Russia, taken around 1910.

The images were taken using a "one shot" color camera. One shot cameras work much like three tube color television cameras. A camera with three negatives with red, green and blue filters in front takes three simultaneous pictures which when projected together recreates a full color image.

This process is essesntially the same additve system as color television or the original three strip Technicolor film system.

The images were projected because at that time printing them was very difficult.

Colormetrically the system is as valid today as it was in the1900s when the photos were taken.

The photo here is of the Monastery of St. Nil' near Moscow and was taken in 1910
