PHOTOGRAVURE - PHOTOGRAPHIC ENGRAVING
"The earliest forms of photogravure were developed in the 1830s by the original pioneers of photography itself, Henry Fox Talbot in England and Nicéphore Niépce in France. They were seeking a means to make prints that would not fade, by creating photographic images on plates that could then be etched. The etched plates could then be printed using a traditional printing press. These early images were among the first photographs, pre-dating daguerreotypes and the later wet-collodion photographic processes."
