The Photochrom process was a technique for colouring black and white negatives by applying them directly onto lithographic plates of different colours, at a time when colour photography, although it had been invented, was technically not really feasible. Photochrom was conceived in 1880 by Hans Jakob Schmid, an employee at the Swiss company Orell Gessner Füssli, which went on to found the Photocrom Zürich company (changing its name in 1889 to Photoglob Zürich). Up until 1890, when the patent was licensed out to other companies like Detroit Photographic Company and the Photocrom Company of London, it enjoyed absolute exclusivity in this startling process, which enabled it to create a flourishing postcard selling industry. Each one bears a number, the initials of the company (P.Z.) and the respective title. Although some are on popular subjects, the majority are views of cities. This kind of geographical image made a significant contribution to a new image of Spain as a country undergoing modernisation, under the guidance of the intellectual principles of Regenerationism.
