Heliograph earthview6/3/2023 ![]() After several days of exposure to sunlight, the plate yielded an impression of the courtyard, outbuildings, and trees outside. He inserted the plate into a camera obscura and positioned it near a window in his second-story workroom. To make the heliograph, Niépce dissolved light-sensitive bitumen in oil of lavender and applied a thin coating over a polished pewter plate. ![]() Over the next decade he tried an array of chemicals, materials, and techniques to advance the process he ultimately called héliographie, or 'sun writing.' ![]() ![]() At his family estate in the nearby village of Saint-Loup-de-Varennes, he produced legible but fleeting camera pictures-or points de vue, as he called them-in 1816. Motivated by the growing popular demand for affordable pictures, Niépce's photographic experiments were conducted with the dual aims of copying prints and recording scenes from real life in the camera. The photograph was made by Joseph Nicéphore Niépce (1765–1833), born to a prominent family at Chalon-sur-Saône in the Burgundy region of France. It is the earliest photograph produced with the aid of the camera obscura known to survive today. The Niépce Heliograph was made in 1827, during this period of fervent experimentation. These astonishing breakthroughs depended upon centuries of developments in chemistry, optics, and the visual arts, accelerating in the decades after 1790. The invention of photography was announced simultaneously in France and England in 1839, dazzling the public and sending waves of excitement around the world.
