The Camera Obscura in Latin means 'Dark chamber'. The dictionary definition for Camera Obscura is a darkened box with a convex lens or aperture for projecting the image of an external object on to a screen inside.
Before photography was created, people already knew the principles of how it eventually got to work. They could process the image on the wall or piece of paper, however no printing was possible at the time as preserving light turned out to be a lot harder task than projecting it.
The Camera Obscura is an ancient optical device. In its most basic form it is, quite simply, a dark room with a small hole in one wall. On the wall opposite the hole, an image is formed of whatever is outside. This image is upside-down (inverted) and back to front (laterally transposed).
The size of the hole has a great effect on the picture that is being projected. A small hole produces a sharp image, which is dim, while a larger hole produces a brighter picture which is less well focused. This is able to happen because, light travels in straight lines.
