Produced New Photographic Plates
Antoine Lumière encouraged the scientific interests of his sons, and over the years the brothers developed their own specialities. Both had a firm grasp of organic chemistry, an asset that would become valuable in their later photographic work. But while Auguste had a preference for topics in biochemistry and medicine, Louis was more interested in the subject of physics. While attending Martinière Technical School, Louis distinguished himself as the top student in his class in 1880. It was during his school years that Louis began working on an improved photographic plate. Originally, "wet" photographic plates had been the only available medium for photography; these were very inconvenient, however, because they required treatment in a dark room immediately before and after the exposure of the plate. A new, more convenient, "dry" plate had been developed and marketed in the 1870s. Louis developed a better version of the dry plate that became known as the "blue label" plate.
The Lumière brothers and their father saw the potential for marketing such a product, and so, with financial backing from Antoine Lumière, the brothers began producing the plates in 1882. The following year, the venture opened a manufacturing facility in Lyons as the Antoine Lumière and Sons company.
