Photography began in 1793 when Nicéphore Niépce experimented with light-sensitive compounds and captured the first photograph of a scene in 1826. Key early developments included the camera obscura, cyanotype process invented by John Herschel in 1842, and the daguerreotype process which produced the first known photo of a person in the 1830s. Henry Fox Talbot invented the first negative in 1841. Eadweard Muybridge took the first multiple photographs of moving objects in the 1870s. The first mass market camera, the Brownie, was invented in 1900 and made cameras affordable to the public.
