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.

Filming in 3DFilming in 3D
• So how are 3D films recorded?– To create the illusion of 3D, a film has to
be shot from two precise angles. Two cameras are mounted together on a rig to film a 3d scene.
