StereoscopyStereoscopy

Stereoscopes (also known as stereopticons or stereo viewers) were a popular form of entertainment during the 1800s.

Stereoscopes are one of the earliest forms of 3D imaging technology.

These viewers allowed users to perceive a still image in “3D” by creating an optical illusion.

be shot from two precise angles. Two cameras are mounted together on a rig to film a 3d scene.
