Long before English astronomer William Talbot produced an image on silver chloride paper, a tiny hole was used by Chinese philosopher Mo-Ti to prove that light travels in straight lines (400 BCE). Even further back in time the pinhole phenomenon was witnessed by our ancestors when a defect in the rock face or animal hide would project an image of the outside world on darkened interior surfaces of caves and tents. The effect is evident in early cave paintings.
