The production of the stereograph entailed making two images of the same subject, usually with a camera with two lenses placed 2.5 inches (6 cm) apart to simulate the position of the human eyes, and then mounting the positive prints side by side laterally on a stiff backing. Brewster devised a stereoscope through which the finished stereograph could be viewed; the stereoscope had two eye pieces through which the laterally mounted images, placed in a holder in front of the lenses, were viewed. The two images were brought together by the effort of the human brain to create an illusion of three-dimensionality. https://www.britannica.com/technology/photography/Development-of-stereoscopic-photography
