They produced it using eight 6.5 by 8.5inch daguerreotype plates, a then-new technology, that in skilled hands of 19th century photographers was capable of displaying mind-blowing resolution.
Fast forward to 2006. To safeguard the image, Van Skalk, the manager of the Cincinnati Public Library, transported the photo to the George Eastman House in Rochester, New York to begin stabilization and conservation work using the most advanced methods of photographic preservation.
Using state-of-the-art digital microscopy, it exposed previously undetected damage to the image - information critical for the preservation specialists. But more importantly, due to the impressive quality of the 19th century daguerreotype, the digital microscope was able to provide an undistorted 30x magnification of the photo - an enlargement revealing unprecedented historic detail of Cincinnati's past.
After the restoration, the historians made a guess on the time and date the photos were taken by using old steamboat records, analysing the angle of shadow etc. They figured the shots must have been taken just before 2pm.
Guess what. There was a clock tower in one of the photos. And using the high-tech microscope scanner, the clock tower showed a time of .......
