Sergey Prokudin-Gorsky
Another very notable practitioner was Adolf Miethe, with whom Prokudin-Gorsky studied in Germany in 1902.[5] Miethe was a photochemist who greatly improved the panchromatic characteristics of the black-and-white photographic materials suitable for use with this method of color photography. He presented projected color photographs to the German Imperial Family in 1902 and was exhibiting them to the general public in 1903,[5] when they also began to appear in periodicals and books. Miethe took the first known aerial color photographs, from a hot air balloon, in 1906.
