Sergey Prokudin-Gorsky, Russian photographer, pioneer of color photography. He used a camera that took a series of three monochrome pictures in sequence, each through a different-colored filter. By projecting all three monochrome pictures using correctly colored light, it was possible to reconstruct the original color scene. Any stray movement within the camera’s field of view showed up in the prints as multiple “ghosted” images, since the red, green and blue images were taken of the subject at slightly different times.
