| Title | Unpublished paper, 'On the phenomenon of relief of the image formed on the ground glass of the camera obscura' by A [Antoine Jean Francois] Claudet |
| Date | 1857 |
| Description | Having observed that the image formed on the ground glass of the camera obscura appears as much in relief as the natural object when seen with the two eyes, Claudet has endeavoured to discover the cause of that phenomenon, and his experiments and researches have disclosed the singular and unexpected fact, that although only one image seems depicted on the ground glass, still each eye perceives a different image; that in reality there exist on the ground glass two images, the one visible only to the right eye, and the other visible only to the left eye. That the image seen by the right eye is the representation of the object refracted by the left side of the lens, and the image seen by the left eye is the representation of the object refracted by the right side of the lens. Consequently these two images presenting two different perspectives, the result is a stereoscopic perception, as when we look through the stereoscope at two images of different perspectives.
