Explanation:
The forerunner to the photographic camera was the camera obscura. Camera obscura (Latin for "dark room") 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 and forms an inverted image (left to right and upside down) on a surface opposite to the opening. The oldest known record of this principle is a description by Han Chinese philosopher Mozi (ca. 470 to ca. 391 BC). Mozi correctly asserted that the camera obscura image is inverted because light travels in straight lines from its source. In the 11th century Arab physicist Ibn al-Haytham (Alhazen)'s wrote very influential books about optics, including experiments with light through a small opening in a darkened room.
The use of a lens in the opening of a wall or closed window shutter of a darkened room to project images used as a drawing aid has been traced back to circa 1550. Since the late 17th century portable camera obscura devices in tents and boxes were used as a drawing aid.

Before the invention of photographic processes there was no way to preserve the images produced by these cameras apart from manually tracing them. The earliest cameras were room-sized, with space for one or more people inside; these gradually evolved into more and more compact models. By Niépce's time portable box camerae obscurae suitable for photography were readily available. The first camera that was small and portable enough to be practical for photography was envisioned by Johann Zahn in 1685, though it would be almost 150 years before such an application was possible.
Early fixed images
The first partially successful photograph of a camera image was made in approximately 1816 by Nicéphore Niépce,[1][2] using a very small camera of his own making and a piece of paper coated with silver chloride, which darkened where it was exposed to light. No means of removing the remaining unaffected silver chloride was known to Niépce, so the photograph was not permanent, eventually becoming entirely darkened by the overall exposure to light necessary for viewing it. In the mid-1820s, Niépce used a sliding wooden box camera made by Parisian opticians Charles and Vincent Chevalier to experiment with photography on surfaces thinly coated with Bitumen of Judea.[3] The bitumen slowly hardened in the brightest areas of the image. The unhardened bitumen was then dissolved away. One of those photographs has survived.
