What is "naturalistic" photography?

In the book Naturalistic Photography written by 1889, Emerson advocated "naturalistic" photography. He believes that no art can reflect nature as accurately and meticulously as photography. Photography is an independent art, and it is not advisable for photographers to imitate the themes and methods of painting. Photography should return to nature to find inspiration, express the image of natural beauty in a realistic way, and achieve artistic effects through photography means such as composition, lighting and focusing, rather than overlapping, splicing and remaking.
