Thatyear ,Daguerre ,another Frenchman, took a picture of his reading room .He used a new kind of camera in a different way. In his picture you could see everything very clearly, even the smallest thing. This kind of photo was called a Daguerreotype.Soon, other people began to use Daguerre’s way. Travelers brought back wonderful photos from all around the world. People took picture of famous buildings, cities and mountains. In 1840, photography was developed.
