Who invented collodion photography?

Isn't it all introduced in the basic book of photography? 1826 The earliest photography was that the French niece was exposed for 8 hours in a painting portrait box with a photosensitive asphalt board. The first photo was called daylight painting. Four years later, the French painter Daguerre invented the silver plate method, and the date of birth of 1839 was recognized as 19. At the same time with Daguerre, the Carroll photography method (the first negative photo printed with negative film) invented by British scientist Talbot 184 1 appeared, but the sensitivity of photosensitive materials in these methods is too low, and the exposure time is about 1 hour. 185 1 Archer, a London sculptor, found through research that if the collodion formed by dissolving the mixed solution of ether and alcohol in nitrocellulose is poured into a proper amount of potassium iodide and coated on clean glass, it will be photosensitive before the solution is dried, and then it will be put into a camera, exposed, developed and fixed to obtain a negative. This method is called wet plate method and collodion photography. Its characteristic is that its sensitivity is much higher than that of the previous silver plate method and Talbot method, but its cost is only 20 times that of the silver plate method. The disadvantage is that you need to bring tents and assistants when you go out to shoot. 187 1 year, British doctor maddox added silver bromide to gelatin emulsion and coated it on glass. After gelatin emulsion is dried on glass, the sensitivity of dry plate method is further improved, and the shutter time is increased to about 65438 0 seconds. Photography finally has the characteristics of instant. 1888, American amateur photographers coated transparent celluloid with gelatin for the first time to make films and films, which are widely used since 100. .......
