The exact date is unknown at the beginning of photography. Born in the dark box on the image to obtain photos, as well as the date of these images is detected by photochemical way.

In the eighth century, an Arab named Jabir Ibn Khayyam's silver nitrate with the impact of the decision to find out the sunlight and the 15th century in the great artist Leonardo da Vinci's existing small hole in the back room to the outside world reflect the views are important elements in the history photography. Dark box they found in the Renaissance era artists. Thus, light enters through a small hole at the other end of the dark box, an inverted image of the subject could see. 18. century to the end of the dark box, frosted glass lens and is placed on the other end can be seen in the image was made out of the box.

The effect of light on chemicals and the silver salt sensitivity of the image deviation of 200 years was known in advance. In 1725, lime and silver nitrate has long been put on paper a way to keep the sun when such an image on paper is seen to occur. 19. paper at the beginning of the century, is immersed in silver nitrate solution was able to obtain negatives. The development of photography and founder of the first, which was made transparent varnish on the paper is to bring an image on tin plates. Then, Yuda tin plate coated with bitumen on the reduction of sunlight falling on an image of the white ground were found.

Niepce in 1829 and began work on the photos Jacques Mande, 1837, together with Daugerre Daugerreotype'ý revealed several developments began to show. This process was mixed with silver powder and olive oil with a copper plate after deletion of the sponge, 1 / 16 ratio in the combination of water and nitric acid washed and heated in a flame to light and nitrate to be required for the second time. Iodine-soaked sheets thus prepared are deployed to the machine, according to light exposure were given 5 to 40 minutes. 47.5 º C. The obtained images covering a tray of mercury into the issue did not arise until.

Spend 16 times more than in 1840, the light exposure time was reduced by using a lens. Daugerre type is very clear image is obtained with a mixture of silver, copper plate is easily broken, and this is a very expensive way to prevent more development.
