What are the characteristics of surrealist photography?

Surrealism photography is one of the schools of modernism photography, and its aesthetic thought is basically the same as surrealism painting. In creation, cutting and darkroom technology are often used as the main modeling means, and the "surreal mysterious world" is expressed through overlapping printing, multiple exposure, grotesque deformation and arbitrary exaggeration. In addition, western modernist photography also includes abstract photography and avant-garde photography.
