"Experience Civil War Photography: From the Home Front to the Battlefront" is a new civil war show that illustrates the rise of photojournalism and new photographic techniques, including stereophotography – a form of 19th-century 3-D imaging.
The Smithsonian blog, "Around the Mall," shared how "during the Civil War, Americans followed the battles at home with collectable photographs of generals and prints of the battlefields that were published in the daily newspaper."
Put on 3-D glasses, and these photographs come to life. Read more about it on Around the Mall.
