We are all aware of the fact that there were no 3D effects 150 years ago. Well, maybe that’s just a theory, because they actually had something alike 3D that they called stereo photography. It was pretty popular during the Civil War in 1861. Here you can see a selection of Civil War photographs that have some kind of 3D effect.

They were all released by The Library of Congress recently. They basically used two 2D images and “melted” them together, so it would look three-dimensional.

The method they used was some sort of digitally converting that made the two images into an anaglyphs, that can be viewed with 3D glasses.

The library has its own Flickr page and website where you can find thousands of photos. Looking at the 3D photos without glasses can be a bit disturbing.
