![]() ![]() On Some Remarkable, and hitherto unobserved, Phenomena of Binocular Vision, in 1838 - one year prior to the established date for the beginning of practical photography. ![]() Wheatstone finally published Contributions to the Physiology of Vision - Part the First. Referring to Wheatstone’s results as “remarkable,” Mayo explained Wheatstone’s investigation into how a “solid object.regarded by both eyes, projects a different perspective.on each retina.” His work investigating stereoscopy was first mentioned in 1833 by Herbert Mayo, Professor of Anatomy at King’s College in London, in his book, Outlines of Human Physiology. ![]() The word “stereoscope,” in reference to the investigation of our mind’s ability to merge two slightly different perspectives into one, instantaneously and without our even being aware of it, so that we are cognizant of our place in three-dimensional space, is attributed to Sir Charles Wheatstone. Although some people theorized that our two eyes allowed us to see “around” an object, there was little understanding as to why drawings and paintings appeared “flat,” despite great efforts by artists to accurately reproduce the subjects being painted. Up until the 1830s, many people believed that we had two eyes simply to see more of an object. In the 1830s, as a revolution in photographic science was occurring, understanding of visual perception, especially as it relates to the understanding of how people perceive depth - binocular vision-was also shifting. Even 3-D film is an old concept as Thomas Edison toyed with the idea of stereoscopic film projection in 1891, the same year the Edison lab revealed its Kinetoscope. The first stereo or 3-D photographs were taken in 1839, the same year recognized as the birth of practical photography. With the recent popularity of movies like Thor and Avatar, some might believe that 3-D technology is a twenty-first century innovation, but it is decidedly nineteenth-century in fact, it is as old as photography itself. ![]()
