Like being there in Hi-rez and Color

  1. Cincinnati waterfront captured on daguerreotype plates c.1848. Restored by conservators at George Eastman House in Rochester, New York. What was unexpected is the resolution of these daguerreotypes. The panoramic set could be blown up to 170 by 20 feet without losing clarity—a digital camera would require 140,000 megapixels per frame to match it. Since the exposure time was on the order of minutes, anything that moved significantly was not imaged. Particularly interesting is seeking out the "ghosts" of slower moving people and horse-drawn buggies moving along the line of sight of the camera.
  2. Photographic survey of the Russian Empire c.1910. Taken by Sergei Mikhailovich Prokudin-Gorskii under the auspices of Tsar Nicholas II before the outbreak of WW1 and the Russian Revolution. This is not (Ted) Turnerization of black and white photographs but a "digichromatographic" restoration of the original color plates. I highly recommend comparing with the more recent photographic views available in the accompanying Google Map links.
