JON GOODMAN PHOTOGRAVURE

Photogravure is the most beautiful and luxurious means of printing the photographic image in ink. The photogravure method used in this portfolio is known as the Talbot-Klîc or dust-grain process... In the early history of what is known today as photography, researchers were looking for a means of printing an image drawn by light, in ink. The development of lithography in 1798 by Aloys Senefelder energized this search. The first photogravure (héliogravure in French) was a reproduction of an engraving of Cardinal D'Amboise, produced in 1826 by Nicéphore Niepce using the light sensitive and acid resistant properties of bitumen of Judea. It happened that producing a richly toned image in ink on plain paper was more difficult and complicated than one produced with a chemical coating of silver salt on a metal support (daguerreotype, 1839) or on coated paper (calotype, 1840). In 1842, the Fizeau process was developed, a technique that etched the daguerreotype image and used it as an intaglio..
