Camera Obscura
Camera Obscura (Latin for "dark room"), sometimes referred to as "pinhole image", is the natural optical phenomenon that occurs when an image of a scene at the other side of a screen (or for instance a wall) is projected through a small hole in that screen as an inverted image (left to right and upside down) on a surface opposite to the opening. The surroundings of the projected image have to be relatively dark for the image to be clear, so many historical experiments were done in literally dark rooms.
The term "camera Obscura" also refers to constructions or devices that make use of the principle within a box, tent or a room. Camera obscure with a lens in the opening have been used since the second half of the 16th century and became popular as an aid for drawing and painting. The device was developed further into the photographic camera early in the 19th century.
A camera Obscura without a lens but with a very small hole is sometimes referred to as a "pinhole camera", although that term more often refers to simple (home-made) lens-less camera in which photographic film or photographic paper is used.
