The world’s first camera was created by Joseph Nicéphore Niépce, a French inventor, in 1816. He developed a device using a primitive photographic process called the camera obscura to capture images. His most significant achievement came in 1826 or 1827, when he produced the first permanent photograph known as “View from the Window at Le Gras” using a process he called heliography.
Niépce’s invention paved the way for modern photography, with further advancements made by inventors like Louis Daguerre and William Henry Fox Talbot.
