The history of photographyand technical background of photography has roots in remote antiquity with the discovery of two critical principles, that of the camera obscura (darkened or obscured room or chamber) and the fact that some substances are visibly altered by exposure to light, as discovered by observation. As far as is known, nobody thought of bringing these two phenomena together to capture camera images in permanent form until around 1800, when Thomas Wedgwood made the first reliably documented, although unsuccessful attempt. In the mid-1820s, Nicéphore Niépce succeeded, but several days of exposure in the camera were required and the earliest results were very crude. Photography is the science, art, application and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film
Photography is the result of combining several different technical discoveries. Long before the first photographs were made, Greek mathematicians Aristotle and Euclid described a pinhole camera in the 5th and 4th centuries BCE.In the 6th century CE, Byzantine mathematician Anthemius of Tralles used a type of camera obscura in his experiments
Ibn al-Haytham (Alhazen) (965 in Basra – c. 1040 in Cairo) studied the camera obscura and pinhole camera,Albertus Magnus (1193/1206–80) discovered silver nitrate, and Georges Fabricius (1516–71) discovered silver chloride. Daniel Barbaro described a diaphragm in 1568. Wilhelm Homberg described how light darkened some chemicals (photochemical effect) in 1694. The novel Giphantie (by the French Tiphaigne de la Roche, 1729–74) described what could be interpreted as photography. Johann Kaspar Lavater invented an apparatus to capture silhouettes by the end of the 18th-Century.
