Early practitioners

Louis Ducos du Hauron conducted early experiments with the three-color principle in the late 1860s. During the period from the 1870s to the 1890s, he created several color prints and photographs.

In 1877, Edward Bierstadt showcased the first successful three-color prints in the United States. His work gained attention in the 1890s when he exhibited color prints of various subjects such as oil and watercolor paintings, floral studies, and portraits from life.

The first person to widely demonstrate good results by this method was Frederic E. Ives, whose "Kromskop" system of viewers, projectors and camera equipment was commercially available from 1897 until about 1907. Only the viewers and ready-made triple photographs for use in them sold in any significant quantity. Still life arrangements, unpopulated landscapes and oil paintings were the typical subject matter, but a few examples of color portraiture from life were also offered.

Another very notable practitioner was Adolf Miethe, with whom Prokudin-Gorsky studied in Germany in 1902. 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, 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.

In England in 1899 Ives's former assistant, Edward Sanger-Shepherd, commercialized the application of the three-colour process in the " Sanger Shepherd process of natural colour photography". With his process in 1903 and 1904 Sarah Angelina Acland produced the first substantial body of work in colour photography by an amateur photographer. By 1905 seventeen different photographers had shown three-colour slides by the Sanger-Shepherd process at exhibitions of the Royal Photographic Society in England.

In 1905, the Neue Photographische Gesellschaft established a color photography studio in Berlin. The studio utilized the three-color principle and employed a printing process developed by Robert Krayn. Some of the resulting images were published as postcards, featuring notable individuals including Kaiser Wilhelm II and Pope Pius X.
