Anaglyphs: How 3D Glasses Work and Their History

The video tutorial explains the use of 3D glasses and anaglyphs, which are stereo pairs of images using different colors to create a three-dimensional effect. It covers the history of anaglyphs, including their discovery in the 1850s by Joseph D'almeida and Louis Dejaron, and their development by Louis Dukharan. The tutorial also discusses modern uses of anaglyphs in comic books and advertising. It explains how 3D glasses work by allowing only certain colors of light through each lens, creating a 3D effect. The video concludes with a fun fact about how scent-triggered memories are more intense.
