The digital archives of centuries-old photographs from the Civil Ware are extensive, thanks to the tremendous efforts of digital archivers, who usually work at non-profits or as volunteers.

But on Tuesday, to commemorate the 150th anniversary of the start of the Civil War, a several organizations have converted old Civil War photos into digital anaglyphs (red/cyan) that add depth, dimension, and additional insight into the years 1861-1865.

The Library of Congress and non-profit Center for Civil War Photography(Opens in a new window) each both launched 3D Civiil War photo exhibits rendered in anaglyphs, those blurry red/cyan photos that pop out when you put on a pair of those chic anaglyphic red/cyan 3D glasses (or by simply crossing your eyes).

“While 19th-century photographic technology could rarely capture action shots of the war, many stereos show the careful preparation for battles, the aftermaths, and close-up scenes in camps and forts,” writes Carol Johnson, a photography curator at the Library of Congress, in a blog post.

Apple iPad users can also purchase History 3D: Civil War for $0.99 instead of $1.99, until April 16. The app’s two dozen 3D photos pulls up stories for every photo as you swipe through. According to developer IggyCo, all the 3D photos will be donated to the Library of Congress.
