When was the color camera invented?

1839, Frenchman Daguerre made the first practical silver camera, which consisted of two wooden cases. One wooden box is inserted into another to focus, and the lens cover is used as a shutter to control the exposure time for up to 30 minutes, so that a clear image can be taken.

There is no distinction between color and black and white in a camera. Black and white photos can be taken with black and white film, and color photos can be taken with color film. The invention of the camera.

186 1 year, Maxwell (Maxwell1831–1879) took the first color photo.

Before 400 BC, Mozi recorded pinhole imaging in Mo Jing. /kloc-in the 0/3rd century, an image black box made of pinhole imaging principle appeared in Europe. People walked into the black box to watch images or paint landscapes.

1550, Italian cardano put the lenticular lens in the original pinhole position, and the image effect is brighter and clearer than the black box.

1558, the Italian Barbaro added an aperture to the device in cardano, which greatly improved the imaging clarity.

1665, John Zhang, a German monk, designed and made a small portable single-lens reflex camera box, which could only be used for painting because there was no photosensitive material at that time. ?

1822, the Frenchman Niepce made the world's first photo on the photosensitive material, but the image was not clear and needed eight hours of exposure. In 1826, he took a photo through a black box on the tin floor coated with photosensitive asphalt. ?

1839, Daguerre made the first practical silver camera, which consisted of two wooden cases. One wooden box is inserted into another to focus, and the lens cover is used as a shutter. Only by controlling the exposure time for 30 minutes can a clear image be taken.

1860, Sutton, England designed the first single-lens reflex camera with a rotatable viewfinder. 1862, Detrie, a Frenchman, stacked two cameras together, one for taking pictures and the other for taking pictures, forming the prototype of a dual-lens camera. 1880, Baker of England made a double-lens reflex camera. ?

With the development of photosensitive materials, dry plates coated with silver bromide photosensitive materials appeared in 187 1 year, and films based on nitrocellulose (celluloid) appeared in 1884. With the appearance of magnifying technology and particle film, the quality of lens has been improved accordingly.

In 1902, Rudolf made a famous "Tiansai" lens by using the third-order aberration theory established by Cedell in 1855 and the high refractive index and low dispersion optical glass successfully researched by Abbe in188/0/year. Due to the reduction of various aberrations, the imaging quality is greatly improved.

On this basis, in 19 13, a small Lycra camera with 35 mm film punched in the negative was designed and manufactured in Barnach, Germany. ?

However, all the 35 mm cameras in this period used perspective viewfinders without rangefinders.

1930 to make color film;

193 1 Germany Contex camera has been equipped with a double-image coincidence rangefinder based on the principle of triangular ranging, which improves the focusing accuracy, and adopts aluminum alloy die-casting body and metal curtain shutter for the first time. ?

1935, a single-lens reflex camera of Ek Saquetoux appeared in Germany, making it easier to focus and change lenses.

In order to make the camera exposure accurate, Kodak camera began to install selenium photocell exposure meter at 1938.

1947, Germany began to produce Contax S five-prism single-lens reflex camera, which made the viewfinder image no longer upside down, and changed the top view to head-up focusing framing, making photography more convenient. ?

1956, the Federal Republic of Germany first manufactured an electric eye camera with automatic exposure control;

After 1960, cameras began to adopt electronic technology, and many forms of automatic exposure and electronic program shutters appeared;

1975, the operation of the camera began to be automated. ?

In 1860, Maxwell (Maxwell1831–1879) studied color negative films, and took the lead in taking pictures of the three primary colors of 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".

In A.D. 1869, Ducos Hauron, a French scientist, was the first to put forward that according to the painter, three basic pigments, red, yellow and blue, were mixed in different proportions to produce color photos. Although his works are not satisfactory, he has made a breakthrough in color photography.

At the end of A.D. 1873, H.W. Vogel1834–1898, a professor at Berlin University of Technology, Germany, immersed the collodion photosensitive plate in the phenylammonium solution and could feel the green light. After this 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, the American inventor Edison (Edison Thomas Alva1847–1931) made the first cinematography.

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.
