The camera obscura first invented by the Iraqi scientist Ibn al-Haytham (Alhazen)was the forerunner to the camera. It is an instrument consisting of a darkened chamber or box, into which light is admitted through a convex lens, forming an image of external objects on a surface of paper or glass, etc., placed at the focus of the lens. The camera obscura was first invented by the Iraqi scientist Ibn al-Haytham (Alhazen) as described in his Book of Optics (1015-1021). Irish scientist Robert Boyle and his assistant Robert Hooke later developed a portable camera obscura in the 1660s.
The first camera that was small and portable enough to be practical for photography was built by Johann Zahn in 1685, though it would be almost 150 years before technology caught up to the point where this was practical. Early photographic cameras were essentially similar to Zahn's model, though usually with the addition of sliding boxes for focusing. Before each exposure, a sensitized plate would be inserted ...more

Some say the first 'camera' was designed before Columbus. It was by simple deduction that an artist noticed a faint image on the opposing wall of a small building where a small hole was in the lighted side of the building. He worked on a lens that could be placed in a similar hole of another building and he noticed that the image on the opposite wall was rather clear, color and all, although upside down. He then proceeded to use oil paints that were in use to paint portaits at the time. He simply mixed the oils to match the colors and painted directly onto the image he was looking at. Todays cameras do the same thing minus the oil paint. Film cameras have replaced the oils with both silver halide salts and dyes. Digital camer ...more
