Stereoscopic Photography - 1918

Stereoscopic autochrome (half shown) photograph 
by an unidentified photographer, approx 1.75" x 4.2", circa 1918.
Special cameras with two lenses side-by-side are required to produce the twin images of a stereo photograph. When placed in a special viewer, stereoscopic photographs like this one appear in lifelike 3D. Natural colour adds to the illusion. Autochromes were made in several stereoscopic formats; this size (above) was introduced by the French camera maker Jules Richard in 1905 and was utilized by both amateurs and professionals into the 1930's.
