Photogravure is an early (18th century) photography was intimately linked with printmaking. In 1829, ten years before Louis Daguerre announced the invention of photography, he formed a partnership with Joseph-Nicéphore Niépce, who, in turn, had been experimenting with light-sensitive materials since the 1810s. Their efforts were motivated by the desire to make stable fixed images directly from nature, or to make "etchings by light."
