A Frenchman Niepce, needed pictures for his business. But he was not a good artist. So he invented a very simple camera in 1826. 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, Dagueme, 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.
In 1840, photography was developed once more. Then photographers could take pictures of people and moving things. But the photographers had to carry many machines.
With the development of science and technology, a Chinese young man Wang Mengqiu, invented Hover Camera (无人相机). It can record people and things more wonderfully. He once studied at Stanford University in the United States. He became famous overnight because of the invention.
