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.
The history of the camera began even before the introduction of photography. Cameras evolved from the camera obscura through many generations of photographic technology – daguerreotypes , calotypes , dry plates , film – to the modern day with digital cameras and camera phones .
View from the Window at Le Gras 1826 or 1827, believed to be the earliest surviving camera photograph. [1] Original (left) and colorized reoriented enhancement (right).. The history of photography began with the discovery of two critical principles: The first is camera obscura image projection; the second is the discovery that some substances are visibly altered by exposure to light.

Early pinhole camera. Light enters a dark box through a small hole and creates an inverted image on the wall opposite the hole. [8]The first known description of pinhole photography is found in the 1856 book The Stereoscope by Scottish inventor David Brewster, including the description of the idea as "a camera without lenses, and with only a pin-hole".
Nineteenth-century artists' use of photography had been well documented, [2] and many art historians had already suggested that certain artists had used the camera obscura for their work (most notably 18th century painter Canaletto and 17th century painter Johannes Vermeer), but Hockney believed that nobody had previously suggested that optics ...
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, 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).
That's when Joseph Nicéphore Niépce started experimenting with a camera obscura and took a snapshot of the view outside his window. Scottish physicist James Clerk Maxwell took the world's first ...
Using the camera obscura, artists would manually trace what they saw, or use the optical image as a basis for solving the problems of perspective and parallax, and deciding color values. A camera obscura optically reduces a real scene in three-dimensional space to a flat rendition in two dimensions.
