A pinhole camera is a camera that is so old that it only has the most fundamental elements. Basically it's just a light proof space with a hole. no buttons to change the aperture or focus, you can't see the picture in the screen right after. Light passes through the aperture, which projects the scene from outside the camera onto the opposite internal side. The image will be inverted and cast onto a light-sensitive surface to capture the photograph. A pinhole camera may also be referred to as a camera obscura- the two words being latin for dark chamber.The earliest recorded mention of a pinhole camera was as early as the fifth century BC, by the Mohist philosopher Mozi. 2 In 1021, the Arabian scientist Ibn al-Haytham wrote about pinhole effects in the Book of Optics. He discovered that by using a smaller pinhole the image appears much sharper, but is also dimmer.
