Humanist Photography, also known as the School of Humanist Photography, manifests the Enlightenment philosophical system in social documentary practice based on a perception of social change. It emerged in the mid-twentieth-century and is associated most strongly with Europe, particularly France, where the upheavals of the two world wars originated, though it was a worldwide movement. It can be distinguished from photojournalism, with which it forms a sub-class of reportage, as it is concerned more broadly with everyday human experience, to witness mannerisms and customs, than with newsworthy events, though practitioners are conscious of conveying particular conditions and social trends, often, but not exclusively, concentrating on the underclasses or those disadvantaged by conflict, economic hardship or prejudice. Humanist photography "affirms the idea of a universal underlying human nature". Jean Claude Gautrand describes humanist photography as:a lyrical trend, warm, fervent, and responsive to the sufferings of humanity [which] began to assert itself during the 1950s in Europe, particularly in France ... photographers dreamed of a world of mutual succour and compassion, encapsulated ideally in a solicitous vision.

The Family of Man was an ambitious exhibition of 503 photographs from 68 countries curated by Edward Steichen, the director of the New York City Museum of Modern Art's (MoMA) department of photography. According to Steichen, the exhibition represented the "culmination of his career". The title was taken from a line in a Carl Sandburg poem.
