Explain the basic principles of photography.

The birth of photography is an artistic revolution based on technology. The publication of photography, rather than the announcement of inventions, was made public by the French government at the French Academy of Sciences in 1839. It can be said that almost all the pioneers of photography are chemists and scientists. Niepce, the inventor of photography, is not a painter, but a technology enthusiast, while Daguerre, the partner, is a choreographer. Besides painting the background of French theaters, his main occupation is art training. It's just that photography is a natural advantage and has developed rapidly in the field of art, thus achieving its own unique art.
