“[...] Up to this time the images that Niėpce produced were heliographic copies of engravings; but in 1827 he produced a heliograph of an outdoor scene, the world’s first photograph. It was a view from the window of his house taken across the courtyard showing a loft, a pear tree and the roof of a barn. Niėpce derived enormous personal satisfaction from this result [...] It was hard to believe that within 10 years these rudimentary images would be transformed into pictures of incredible detail and fidelity.” ― Bede Morris
