     In 1826, a Frenchman named Niepce needed pictures for his business. But he was not a good artist.

So he invented a very simple camera (照相机). He put it in a window of his house and took a picture of

his garden. That was the first photo.

     The next important date in the history of photography (摄影术) was in 1837. That year, Daguere,

another Frenchman, took a picture of his reading room. He used a new kind of camera in a different way.

a Daguerreotype.
