I knew old cameras needed a long exposure, but an entire year?!
The exposure was 14 days, but OP didn’t know that some people claimed it was done on 1826 and others in 1827.
I was joking.

Niepce is ill treated by history. People who know a bit remember Daguerre, because of the daguerreotype, but Niepce is the first one to develop the process.
There’s a nice museum in his birthplace in Châlons sur Saône for those interested, and geologically suited.
From wikipedia:
View from the Window at Le Gras (French: Point de vue du Gras) is the oldest surviving photograph. It was created by French inventor Nicéphore Niépce between June 4 and July 18, 1827, in Saint-Loup-de-Varennes, France, and shows parts of the buildings and surrounding countryside of his estate, Le Gras [fr], as seen from a high window. The image was created by heliography, a process which Niépce had invented around 1822, and which uses the hardening of bitumen in light to record an image after washing off the remaining unhardened material.
