First Camera!!!




The ancient Greeks thought our eyes emitted rays, like a laser, which enabled us to see. The first person to realize that light enters the eye, rather than leaving it, was the 10th-century Muslim mathematician, astronomer and physicist Ibn al-Haytham. He invented the first pinhole camera after noticing the way light came through a hole in window shutters. The smaller the hole, the better the picture, he worked out, and set up the first Camera Obscura (from the Arab word Qamara for a dark or private room). He is also credited with being the first man to shift physics from a philosophical activity to an experimental one.
A pinhole camera, also known as camera obscura, or "dark chamber", is a simple optical imaging device in the shape of a closed box or chamber. In one of its sides is a small hole which, via the rectilinear propagation of light, creates an image of the outside space on the opposite side of the box.
