Photography coming from the pictures of East Anglian life publication. Emerson used the platinum process in rare occasions. William Willis made the first platinum print in 1873 and patented it, but the process was imperfect, attracting little interest. In 1874, the British Journal of Photography announced his Platinum Printing process. By 1879 he had improved the process sufficiently to justify founding the Platinotype Company to market his papers. He began marketing his pre-coated papers in 1880. Taking his cue from Daguerre's marketing practices with his Daguerreotypes, Willis sold licenses to photographers wanting to use his process, and then sold them the materials.
