Heliography

This earliest known surviving heliographic engraving, printed from a metal plate made in 1825 by Joseph Nicéphore Niépce using his "heliographic process".[1] The plate was exposed under an ordinary engraving. Heliography was also used to capture a scene directly from nature with a camera.
This article is about the photographic process. For other uses, see Heliography (disambiguation).

Heliography (in French, héliographie) from helios (Greek: ἥλιος), meaning "sun", and graphein (γράφειν), "writing") is the photographic process invented, and named thus, by Joseph Nicéphore Niépce around 1822,[1] which he used to make the earliest known surviving photograph from nature, View from the Window at Le Gras (1826 or 1827), and the first realisation of photoresist[2] as means to reproduce artworks through inventions of photolithography and photogravure.
