What is the principle of "area exposure method" created by Adams?

In order to pursue technical perfection, Adams created the "regional exposure method". This method can predict the rich colors of the work before shooting, and control these colors through post-production, forming a delicate and rich level and texture. In his works, the rich hue and clarity between black, white and gray levels are fully reflected, and the beauty of black and white photography is interpreted to the extreme by him. Adams's landscape photography works are concise and fresh, with rigorous composition and delicate levels. Musical sense, philosophy and solemn classical beauty are the characteristics of his landscape works. Perhaps it is for this reason that when we appreciate Adams' landscape photography, we will get a soothing, intense, relaxed or deep musical feeling because of the rhythm and melody composed of different tone levels on the screen. Adams combined passion and technology perfectly and gained unparalleled authority in the field of landscape photography. After him, no one can surpass. So in a sense, Adams has become a milestone and has an unshakable position in the history of photography.
