Beg a strong man to tell me the origin of the photo. Now that photos have retired from life, please talk about their invention history, popularization and subsequent decline.

Photos are images from photography, starting with 1826. Photons are usually collected by photosensitive paper, and the principle of light phase formation is to produce still images on radiation-sensitive materials such as photosensitive film, paper, glass or metal through the chemical action of light. Most photos are taken by cameras, both positive and negative.

The world's first photograph (named "Scenery Outside the Window of Legolas") was created by the French inventor Joseph Nicéphore Niépce in 1826. This photo shows the courtyard and outhouse outside the window upstairs of his house. The shooting method is exposed on the asphalt metal plate in the pinhole camera.

184 1 year, William Henry Fox Talbot, an Englishman (1800- 1877) published "Carlo Photography", which made a negative that could be copied many times, laying a foundation for the photography process of modern photography. In China, photography was introduced to China by western missionaries in the Qing Dynasty. In the early years of the Republic of China, many businesses with this industry began to rise.

The oldest photo in Japan is Koichi Tanaka, which was taken in 1854, and the photography technology was officially introduced to Japan in 1905. Taiwan Province Province introduced photography technology during the Japanese occupation period, so it followed the Japanese translation of title photos. In the streets and alleys, shops that take this as their profession are called photo studios. However, after the 1950 s, the Kuomintang moved to Taiwan Province and changed its name to photography, photo studio and photo studio. It was not until the 1980' s that the Japanese entertainment circle opened, and the word "photo studio" flourished again.

1860, Maxwell (Maxwell1831–1879) studied color negative films, and took the lead in taking pictures of three primary colors, namely red, green and blue, and then superimposed and projected them to form a color image. This is the process of adding color, which leads to the principle that color TV can develop color. From then on, world photography began to move from black and white to color. That is, the rise of what people call the "color photography era".

1869, Ducos Hauron, a French scientist, was the first in history to put forward the idea that three basic pigments, red, yellow and blue, were mixed by artists in different proportions to make color photos. Although his works are not satisfactory, he has made a breakthrough in color photography.

At the end of 1873, H.W. Vogel (1834–1898), a professor at Berlin Technical University, Germany, soaked the collodion photosensitive plate in phenylammonium solution, and then it could feel green light. As soon as the experiment was published, scientists were encouraged to look for other color photosensitive additives. Photographic film can only perceive blue light at first, and then it can perceive purple light. In AD 1874, it can sense yellow light, and in AD 188 1, it can sense red light. At this time, the negative can have a "color sense" for red, orange, yellow, green, blue and purple, but the brightness of the photo needs to be improved.

1888, Edison Thomas Alva, the greatest inventor in the world, made the first cinematography in history. On a 50-foot-long film, 600 images were shot continuously and put in a big box with a viewing hole. One person can watch the scenery for about one minute, which is called "watching westerns" in China.

1889, Edison cooperated with Hysmans to establish the future film and camera, film format and hole spacing. This is the beginning of the "standardization" of manufacturing photographic equipment all over the world, which is of great significance.

1In February, 894, Edison built the world's first film studio and filmed the first film "Black Maria", and then "watching westerns" became popular all over the world.

189 1 year, the French physicist lippmann Gabriel (1845–1921) announced a novel color photography method without dyes. He is a famous professor at the University of Paris, and won the Nobel Prize in A.D. 1908 for being the first to make a "color photographic negative" by scientific method. He used technology to add a layer of reflective mercury to the full-color emulsion, so that the light and shadow passed through the emulsion, and then reflected back to "interfere" with the incident light and shadow into a latent image, which would be accepted. Each color has a different image, which is obviously vivid when viewed. However, the production process of color negative by Lips method is very complicated, which can not be printed repeatedly and needs long exposure, so it cannot be popularized. However, he applied science to the development of photography and made great contributions, so the Nobel Prize was awarded.

1894, Lumiere August and Louis1862.1864–1954.1948 invented the real color negative, which was recognized as a revolutionary event of "color photography".

In China, color photos became popular in the late 1970s and early 1980s, and in China's first tier cities. If popularization means widespread use, it is to use non-digital cameras first and then digital cameras. Its spread is not only determined by the film price, because color development is not something we can do by ourselves, so it depends on the development of supporting facilities, so it was really widely used in China in the 1990s, because printing equipment began to be widely used.

According to historical records, the earliest color photos taken in China should be the photos of founding ceremony on 1949+ 10/0/day when New China was founded.

It was probably popular abroad in the 1960s. The invention of color photography was invented by American photographer Levi Hill in 1839. Since then, colorful natural colors have become the goal pursued by photographers. Of course, before this, some customers often asked photographers to color photos by hand, but these artificial colors were far from the real colors.

/kloc-in the 1990s, the original negative and camera photography technology was gradually replaced by digital electronic technology.
