What is strand's shooting concept?

Strand was a representative figure who opposed photo photography in the early 20th century. He advocates giving full play to the specialty of photography and bringing people back to real daily life from the dream world created by art photographers. In his work "Blind Girl", the realistic picture composed of dark background, rough shadow lines and signs on his chest is sweet and sad by photo photography. Unreal pictures are out of place, and the value scale of beauty has a new standard here. In strand, the pursuit of "beauty" in photo photography is not important. For him, understanding and expressing the real life itself is more important.
