A camera obscura (pl. camerae obscurae or camera obscuras; from Latin camera obscūra ' dark chamber ') [1] is the natural phenomenon in which the rays of light passing through a small hole into a dark space form an image where they strike a surface, resulting in an inverted (upside down) and reversed (left to right) projection of the view outside.
An 18th-century artist utilizing a camera obscura for image tracing. The camera obscura (from the Latin for 'dark room') is a natural optical phenomenon and precursor of the photographic camera.

The first camera that was small and portable enough to be practical for photography (that is, actually capturing the image on some sort of medium) was envisioned by Zahn in 1685 [citation needed], though it would be almost 150 years before technology caught up to the point where this was possible to actually build (see History of the camera).
The first permanent photograph, a contact-exposed copy of an engraving, was made in 1822 using the bitumen-based "heliography" process developed by Nicéphore Niépce.The first photographs of a real-world scene, made using a camera obscura, followed a few years later at Le Gras, France, in 1826, but Niépce's process was not sensitive enough to be practical for that application: a camera ...
A camera obscura used for drawing. Photography is the result of combining several technical discoveries, relating to seeing an image and capturing the image. The discovery of the camera obscura ("dark chamber" in Latin) that provides an image of a scene dates back to ancient China.
The camera obscura was well known for centuries and documented by Ibn al-Haitham in his Book of Optics of 1011–1021. In 13th-century England Roger Bacon described the use of a camera obscura for the safe observation of solar eclipses , exactly because the viewer looks at the projected image and not the sun itself.
