Who invented the camera?

The world's first camera (1839) was manufactured by Alfonsky Locks in Paris, France. Around 370 BC, Mohist school described the principle of pinhole imaging. 1839, 19 In August, France announced to the world the photographic works of the artist L Daguerre (1787- 185 1). After the invention of photography, it quickly swept the world. With the development of human science and technology and the progress of material civilization and spiritual civilization, it has become people's work. The earliest cameras can be traced back to 1830~ 1880. Sliding-box cameras (also called flat-panel cameras) produced in France, Britain, Austria, Belgium and other countries use two black boxes to move and adjust the focal length, and the speed is controlled by the lens cover. The photosensitive plate is made of nitrocellulose dissolved in the mixed solution of alcohol or ether (collodion). Sodium iodide (potassium iodide) and a small amount of potassium bromide are mixed evenly in collodion, then coated on the glass plate, and then the coated glass plate is put into the silver nitrate solution in a sealed black box, with silver nitrate and iodine in the emulsion. In the 1930s and 1940s in China, this method was also adopted by small photo studios-coating iodine silver bromide emulsion on glass plates, commonly known as glass negatives. 1888, george eastman of the United States invented the first Kodak camera with film in the world-Kodak camera 1. 1924 Lai Ci company invented the first 35mm Leiez camera. 1937 Germany produced the world's first 35mm single-lens reflex camera-Axeti. 1959, zoom lens for photography produced by Austrian Fu Lunda company. 1977, Japan's Kobayashi VI company manufactured the world's first autofocus camera. From 65438 to 0988, Japan produced the world's first fully automatic single-lens reflex camera-Minolta 7000I, which can automatically focus on moving objects. 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. He felt that he lacked financial resources, energy and material resources before agreeing to cooperate with L. Daguerre.1829 65438+On February 4, 2009, the two sides signed a ten-year cooperation agreement. In order to help each other and learn from each other's strengths, they announced themselves. 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.
