Stereoscopy involves creating an illusion of depth in an image or movie by presenting two slightly offset perspectives. Each perspective is intended for a separate eye, creating a three-dimensional effect when viewed through stereoscopic devices, such as 3D glasses. Stereoscopy leverages the human brain’s ability to perceive depth through the slight disparity between the images seen by each eye.

In filmmaking and photography, stereoscopy adds an extra dimension to the visual experience. It enhances the sense of immersion and realism, making objects appear to have depth and volume. Stereoscopic techniques have been employed in various media, from cinema to virtual reality, offering audiences a more engaging and visually dynamic viewing experience.
