Incredible 3D Stereoscopic Civil War Photos Stereoscopic images basically involve taking 2 or more static images, from slightly different angles, to create a 3D effect that tricks the eye into noticing the depth of field, angles and perspective of the image. Thus, it’s possible to take a flat image and create 3D depth to it. When applied to older photographs, it’s an amazing technique, because it brings life to history. Take for example, these Civil War photographs that use a stereoscopic effect!
