What is the doctrine of materializing imaginary things?

Surrealism photography: Surrealism photography is a genre that emerged in the field of photography art during the decline of Dadaism in the 1930s. This school has strict art courses and theories. They believe that it is a task that classical artists have already completed to express the real world with realistic creative methods, while the mission of modern artists is to explore the new and unexplored "spiritual world" of mankind. Therefore, people's subconscious activities, accidental inspiration, psychopathy and dreams have become the objects of surrealist photographers' deliberate performance.

Famous photographers of this genre include Paerhan, a painter engaged in surrealist highlights; Deformed human photographer Brent; Portrait and publicity photographers Carson, Blumenthal, Lorraine, Halsman, Lion, etc.
