The history of 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 (film) can only perceive blue light at first, and then it can perceive purple light. In A.D. 1874, it could sense yellow light, and in A.D. 188 1 year, it could 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.

After AD 1904

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.
