Joseph Niépce naît le 7 mars 1765 à Chalon-sur-Saône en Bourgogne sous le règne de Louis XV. Son père, Claude Niépce, conseiller du Roi, est avocat à la Cour, receveur des consignations à Chalon-sur-Saône et intendant du Duc de Rohan-Chabot qui le tenait en estime. Sa mère, née Claude Barault, est la fille d'Antoine Barault, avocat et conseiller du Roi. Très aisée et l'une des plus anciennes de Chalon, la famille Niépce possède des propriétés dispersées autour de la ville, procurant à Joseph des revenus élevés. Il adopte le surnom de Nicéphore selon certains lors de la période révolutionnaire; quand d'autres expliquent qu'il a choisi « Nicéphore » en 1787, mille ans après la fin du premier iconoclasme en 787, après avoir été renvoyé du lycée pour avoir montré des images de lanterne magique à sa classe.

The date of Niépce’s first photographic experiments is uncertain. He was led to them by his interest in the new art of lithography, for which he realized he lacked the necessary skill and artistic ability, and by his acquaintance with the camera obscura, a drawing aid which was popular among affluent dilettantes in the late 18th and early 19th centuries. The camera obscura’s beautiful but fleeting little “light paintings” inspired a number of people, including Thomas Wedgwood and Henry Fox Talbot, to seek some way of capturing them more easily and effectively than could be done by tracing over them with a pencil.

Letters to his sister-in-law around 1816 indicate that Niépce had managed to capture small camera images on paper coated with silver chloride, making him apparently the first to have any success at all in such an attempt, but the results were negatives, dark where they should be light and vice versa, and he could find no way to stop them from darkening all over when brought into the light for viewing. Niépce turned his attention to other substances that were affected by light, eventually concentrating on Bitumen of Judea, a naturally occurring asphalt that had been used for various purposes since ancient times. In Niépce’s time, it was used by artists as an acid-resistant coating on copper plates for making etchings. The artist scratched a drawing through the coating, then bathed the plate in acid to etch the exposed areas, then removed the coating with a solvent and used the plate to print ink copies of the drawing onto paper. What interested Niépce was the fact that the bitumen coating became less soluble after it had been left exposed to light.

Niépce dissolved bitumen in lavender oil, a solvent often used in varnishes, and thinly coated it onto a lithographic stone or a sheet of metal or glass. After the coating had dried, a test subject, typically an engraving printed on paper, was laid over the surface in close contact and the two were put out in direct sunlight. After sufficient exposure, the solvent could be used to rinse away only the unhardened bitumen that had been shielded from light by lines or dark areas in the test subject. The parts of the surface thus laid bare could then be etched with acid, or the remaining bitumen could serve as the water-repellent material in lithographic printing. Niépce called his process heliography, which literally means “sun drawing”. In 1822, he used it to create what is believed to have been the world’s first permanent photographic image, a contact-exposed copy of an engraving of Pope Pius VII, but it was later destroyed when Niépce attempted to make prints from it. The earliest surviving photographic artifacts by Niépce, made in 1825, are copies of a 17th-century engraving of a man with a horse and of what may be an etching or engraving of a woman with a spinning wheel. They are simply sheets of plain paper printed with ink in a printing press, like ordinary etchings, engravings, or lithographs, but the plates used to print them were created photographically by Niépce’s process rather than by laborious and inexact hand-engraving or drawing on lithographic stones. They thus are photo-etchings. One example of the print of the man with a horse and two examples of the print of the woman with the spinning wheel are known to have survived. The former is in the collection of the Bibliothèque nationale de France in Paris and the latter two are in a private collection in Westport, Connecticut.
