1889
Old stereoscopic view Paris Place de l'Opéra
 
A stereoscopic image is made up of two photos, called left and right, taken by two optical sensors from the same scene from two slightly distant points of view, but imperatively at the same height and distance from the foreground. These two views can then be presented to the viewer in such a way that the image from the left camera is seen only by the left eye, and the image from the right camera by the right eye to give a relief effect.
