Since the late 17th century, portable camera obscura devices in tents and boxes were used as drawing aids. Camera Obscura were used as drawing aids since at least circa 1550. Ibn al-Haytam's writings on optics became very influential in Europe through Latin translations, inspiring people such as Witelo, John Peckham, Roger Bacon, Leonardo da Vinci, René Descartes and Johannes Kepler. He also first understood the relationship between the focal point and the pinhole, and performed early experiments with afterimage. While the effects of a single light passing through a pinhole had been described earlier, Ibn al-Haytham gave the first correct analysis of the camera obscura, including the first geometrical and quantitative descriptions of the phenomenon, and was the first to use a screen in a dark room so that an image from one side of a hole in the surface could be projected onto a screen on the other side. The invention of the camera has been traced back to the work of Ibn al-Haytham, who is credited with the invention of the pinhole camera. 965–1040 AD), an Arab physicist also known as Alhazen, wrote very influential essays about the camera obscura, including experiments with light through a small opening in a darkened room. Light enters a dark box through a small hole and creates an inverted image on the wall opposite the hole. 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. By Niépce's time, portable box camera obscurae suitable for photography were readily available. The earliest cameras were room-sized, with space for one or more people inside these gradually evolved into more and more compact models. Since the late 17th-century portable camera obscura devices in tents and boxes were used as a drawing aid.īefore the invention of photographic processes, there was no way to preserve the images produced by these cameras apart from manually tracing them. 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.
In the 11th century, Arab physicist Ibn al-Haytham (Alhazen) wrote very influential books about optics, including experiments with light through a small opening in a darkened room. Mozi correctly asserted that the camera obscura image is inverted because light travels in straight lines from its source. The oldest known record of this principle is a description by Han Chinese philosopher Mozi ( c. 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 forerunner to the photographic camera was the camera obscura.
