When does the color camera appear?

1845, German von Martens invented the world's first 150 turning point. 1849, Davie-Blue Scott invented a stereo camera and a two-lens stereo observation mirror. 186 1 year, physicist Maxwell invented the world's first color photo.

The first chapter is a brief history of camera development.

An opaque box. This is a camera. A camera is a photographic equipment that uses photographic film to shoot a scene. Its invention took a long time.

China has a long history in studying light and images. As early as more than 400 years BC, China's book Mo Jing recorded in detail the straight-line advance of light, the reflection of light and the imaging phenomena of plane mirror, concave mirror and convex mirror. In the Song Dynasty, Shen Kuo's Meng Qian Bi Tan (103 1 to 1095) also described the principle of pinhole imaging box in detail.

/kloc-During the Renaissance in the 6th century, an "imaging camera box" for painting appeared in Europe.

1839 On August 9th, the French painter Daguerre announced his invention of silver plate photography, which gave birth to the world's first portable wooden box camera.

184 1 year, optician Vogeland invented the first all-metal camera. The camera is equipped with the world's first photographic lens with the maximum phase aperture of 1: 3.4 designed by mathematical calculation.

1845, German von Martens invented the world's first 150 turning point. 1849, Davie-Blue Scott invented a stereo camera and a two-lens stereo observation mirror. 186 1 year, physicist Maxwell invented the world's first color photo.

1866, German chemist Short and optical scientist Arjun invented barium crown optical glass in Zeiss Company and produced positive photographic lens, which made the design and manufacture of photographic lens develop rapidly. 1888 Kodak company produced a new type of photosensitive material-soft and windable "film". This is a leap in photosensitive materials. In the same year, Kodak invented the world's first portable square box camera with film.

1906 American George hillas used the flash for the first time. 19 13 german oskar barnack developed the world's first 135 camera.

From 1839 to 1924, in the first stage of the development of this camera, some novel cameras such as buttons and pistols also appeared.

From 1925 to 1938 is the second stage of camera development. During this period, German companies such as Leeds, Lorelei and Zeiss developed and produced dual-lens and single-lens reflex cameras with small volume and aluminum alloy body.

At this stage, the performance of the camera is gradually improved and perfected, optical viewfinder, rangefinder and self-timer are widely used, and the adjustment range of mechanical shutter is constantly expanding. The camera manufacturing industry began to produce cameras on a large scale, and camera manufacturers all over the world copied Leica and Lorelei cameras. The sensitivity, resolution and tolerance of black and white photographic film are constantly improving; The popularization of color photographic film has made the photographic team expand rapidly and move towards specialization.

After 1939, it is the third stage of camera development. In the first half of this stage, that is, before the 1960s, the quality of black-and-white and color films was further improved, and the optical industry produced new optical glasses containing rare elements such as lanthanum, titanium and cadmium. So as to better correct the aberration of the photographic lens, and the lens develops rapidly in the direction of large aperture and various focal lengths. So there are many kinds of photographic lenses, such as zoom, emblem distance, catadioptric and wide angle. Single-layer coating of lenses has been widely used. There are some structures in the camera, such as automatic reset of counter, automatic reset of mirror, semi-automatic and full-automatic contraction of aperture. The quality and output of cameras began to develop rapidly.

From the early 1960 s to the present, it is the late stage of the third stage. During this period, Liu Xiaoxi Photography Company produced the world's first self-sustaining focusing camera-Konica C35A camera 135. Then Japan produced the world's first double-priority automatic exposure camera-Minolta XDG camera 135 single-lens reflex camera. There is a precedent that a camera has multiple exposure functions.

During this period, the theory of optical transfer function entered the field of optical design, and a photographic lens with high imaging quality, good color reproduction, large aperture and small distortion appeared. At the same time, the lenses have also developed into a series, from fisheye lenses with a focal length of several millimeters to super telephoto lenses with a focal length of 2 meters, as well as photographic lenses such as angle adjustment, zoom badge distance and night vision. Electronic technology has gradually penetrated into the camera, and various photometry, high-precision electronic mirror shutter, electronic focal plane shutter and easy-to-control electronic selfie have appeared one after another. Exposure compensation, memory storage, multiple recording functions, electric winding, autofocus and other functions are applied more and more beautifully, and the degree of automation, miniaturization and portability have reached an unprecedented height. With the development of high technology, a variety of new cameras for quality evaluation are constantly coming out, thus providing excellent equipment for the creation of photographic art.

When was the color camera invented?

1938, the German Fletcher Siegel put forward the idea of three guns and three beams color kinescope.

1949, the United States first developed the world's first three-gun three-beam color picture tube;

1957, an all-glass color kinescope was developed.

1964, a rectangular picture tube with full glass shell was developed;

1969 A kinescope with black background was developed, and the brightness was doubled.

1968, Sony Corporation of Japan developed a three-color display tube with one gun;

1972, the United States successfully developed a color display tube with automatic convergence error correction.

The use of color camera is very simple, usually as long as the lens is installed correctly, the signal line is connected and the power supply is connected. However, in actual use, if the lens cannot be installed correctly and the state of the color camera and lens cannot be adjusted, the expected use effect may not be achieved.

Extended data

If you use a color camera in the situation where the illumination changes greatly, it is best to connect the automatic aperture lens and turn off the electronic shutter switch of the camera.

If you choose manual aperture, you should turn on the electronic shutter switch of the camera. When the application site is brightest (the ambient light illumination is maximum), the aperture of the lens should be as large as possible, and the imaging is still the best (the image should not be too white and overloaded). Adjust the lens. Just install the protective cover and bracket.

When did humans have color photography?

From the reference books, we can see that experts have selected various representative beautiful photos (many of which have never been published) from the archives of the Institute and compiled them into collections, which are milestones in various periods, from the first color photo in National Geographic magazine in 19 10 to the first underwater color photo in 1927.

The earliest color photo was 19 10 year!

About negation:

1904, the Frenchman Lumiere Augustins-Louis (1862.1864 _1954.1948) invented the real color negative.

In 180 1 year, British physicist Thomas Young (1777 _ 1829) published his research on "color", saying that human eyes can have three kinds of "color perception" of visual nerves: red light, green light and purple light. In addition, it is said that the three basic colors of red, green and purple are mixed together in nature, so we can feel many different colors.

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 color superposition, which leads to the principle that color TV can display colors. 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, the French scientist Dukao Shaolong was the first to put forward that according to the painter's statement, 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. Once 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.

In a.d. 1888, Edison (Edison Thomas Alva 1847 _ 193 1), the greatest inventor in the world, made the first cinematography in history. In a 50-year-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.

In A.D. 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 first 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 _ 192 1) 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.

In 1904, the color negative was invented by a Frenchman, Lumiere Augustins-Louis (1862.1864 _1954.1948), which was recognized as a revolutionary event of "color photography". The Lumiere brothers are great inventors who have never seen in the world to make photographic equipment. Before they were twenty, the two brothers set up a factory to make photographic equipment. In A.D. 1894, they produced and sold nearly two million negatives a year. Yes 1958, Pentax applied for the patent of SMC coating technology, and developed and produced SMC lens by using SMC technology, which greatly improved the lens in color reproduction and brightness, eliminated glare and ghost, thus significantly improved the lens quality and manufactured a color camera.

When did the color camera appear?

Cameras are colorless, and all cameras can be color cameras. Because the color of the photo depends on the film, there have been color photos since the appearance of color film (1936), and the earliest time should be in the 1940s.

Large-size color photographs using film have appeared in China since 1980s. Color digital photos, only ten years.
