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.

Street photography is photography conducted for art or inquiry that features unmediated chance encounters and random incidents within public places, usually with the aim of capturing images at a decisive or poignant moment by careful framing and timing. Although there is a difference between street and candid photography, it is usually subtle with most street photography being candid in nature and some candid photography being classifiable as street photography. Street photography does not necessitate the presence of a street or even the urban environment. Though people usually feature directly, street photography might be absent of people and can be of an object or environment where the image projects a decidedly human character in facsimile or aesthetic.
