Are you ready for a mind-bending experience? The 150th anniversary of the beginning of the Civil War brings about familiar images and also reveals completely new ones. Shannon Perich of NPR shares how the images are made: "A stereoview is two photographs of the same scene taken from two slightly different perspectives, mounted side by side on a card; the photos combine and appear three-dimensional when seen through a viewing device called a stereoscope."
The Photographic History Collection at the Smithsonian holds over 35,000 stereoviews of numerous themes by more than 400 makers, photographers and distributors. It's amazing how far along we've come in photography and technology since the Civil War. Now, we can appreciate these historical moments in incredibly interesting ways.
