When was color photography invented?

1904, Lumiere August and Louis1862.1864–1954.1948 invented the real color negative, which was recognized as a revolutionary event of "color photography".

Also known as color photography. I once called for achromatic photography. The color of the object can be faithfully reproduced. Using color negative film, he is good at photographic collection and large magnification, and color reversal film is good at color restoration, slide show fast, printing manuscript and so on. The printing of color negative film reduces the cost because of automation, which is comparable to black and white photos, but the durability of photos is still problematic.

Photography that uses light and color to reproduce pictures of nature and life. Firstly, the color photosensitive negative is exposed and developed to form a negative image complementary to the color of the scene, and then printed on the positive photosensitive material or enlarged into positive films and photos consistent with the color of the scene.

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.

1904, Lumiere August and Louis1862.1864–1954.1948 invented the real color negative, 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.
