A new iPad app developed from images from the Library of Congress is giving viewers a look at the Civil War in 3D.
The app is called "History 3D: Civil War."
It includes images from photographers such as Mathew Brady and Alexander Gardner.
The 3D images were created from the original glass-plate negatives held by the Library of Congress.
Matt Raymond, the library's former communications director, created the app and will donate the 3D images back to the library. He says many familiar Civil War images have a different look in 3D.
About 24 images are presented, along with pop-up commentary.
Other images from key Civil War battles and other events will be released later.
The app has been launched on iTunes and can be downloaded for $1.99.
