Stereoscopy

Definition

Stereoscopy is a technique that creates the illusion of depth in images by presenting two slightly different perspectives of the same scene to each eye. This method enhances the viewing experience by allowing the viewer to perceive three-dimensionality in photographs and illustrations. In the context of historical photography, stereoscopy played a vital role in conveying realistic representations of events and environments, particularly during significant periods like the American Civil War.
