What is genre history?

Although photography has a history of only 100 years since its birth, it has developed rapidly, and various styles and schools have appeared in all countries in the world. The most important one is painting photography, which originated in Britain from the middle of 19 century and soon spread all over the world, becoming the earliest and most influential school in the history of photography. This school pursues painting effect in its creation, and its works range from composition layout to light and shadow. Documentary photography is still the most important school in photography art, which emphasizes the documentary nature of photography, pays attention to directly and realistically reproducing objective real life and advocates unpretentious artistic style from the characteristic that cameras can truly restore the face of objective things. Impressionist photography is a reflection of impressionism in the field of photography. It advocates that photography should express the photographer's instantaneous impression and unique feelings, pay attention to formal beauty and decoration, pursue a vague and picturesque effect in photography, and pay special attention to the expression of color and light. 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.
