Explore the development of photos

Since the birth of 1839, although it has a history of only 160 years, she has constructed a new style-modern image for the spiritual culture of human society. The contribution of photography to human civilization cannot be overestimated.

The 20th century is an important milestone in the development of photography. With the progress of human society, she has matured and perfected step by step. At the turn of the century, this website specially arranged the photographic events that took place in the 20th century from books and materials such as History of Photography, History of Photography in the World and History of Photography in China, in order to provide readers with entertainment.

In 350 AD, Aristotle first mentioned the principle of pinhole mirror box in his article "Problemata". In A.D. 1 100, Alhasen discussed the application of pinhole mirror box and the principle of reflection law. In 1250, the Dominican monk Magno pointed out that silver salt turned black.
