The first camera

As we all know, photography was invented by French L Daguerre. 1839 August 19 France announced to the world. L Daguerre's full name is Louis Jacques Mond Daguerre. Born in1787-died in 185 1 year. He is a landscape painter who is good at painting the stage background. At that time, a tool-black box was popular in landscape painting and painting. The function of the black box: the scene enters the 45O mirror in the black box through the lens and then reflects on the ground glass above the black box, and then a canvas is laid on the ground glass for painting. By chance, he found a faint shadow on the canvas left on the camera yesterday, so he found out how to leave the image on the camera glass on the canvas. Daguerre learned that J.N. Nipps was also doing experiments in this field. At this time, J.N. Nipps was over 60 years old, and he felt that his financial resources, energy and material resources were insufficient, so he agreed to cooperate with L.Daguerre.1829 65438+signed a cooperation agreement of 10 on February 4, 2009. The two sides announced the research results in order to help each other and learn from each other's strengths. The two sides agreed to publish the research results in their own names and share the benefits equally.

Chaion, the residence of J n Nipes, signed an agreement with L Daguerre, and immediately took out his detailed production method and made a demonstration, but L Daguerre didn't take anything out, so some people suspected that L Daguerre hadn't tested the results yet. After the agreement was signed, the two sides conducted their own experiments and never met again. 1833, J. N. Nippes died, and his son I. Nippes inherited the cooperative relationship. Unfortunately, I Nipes didn't want to do any experiments, so L Daguerre was left to explore alone.

1837, after eight years of exploration, l Daguerre finally succeeded in shooting a still life movie under natural light. 1839, 19 In August, the first page of the world photography history was opened-the French Academy of Sciences and the Academy of Fine Arts held a grand meeting, at which this great invention-black box lithography (photosensitive plate) was announced as a positive film shooting.

So the first camera in the world and the methods of exposure, development and fixing were all invented by L Daguerre.
