Document 6: New York school of photography: The New York school of photography is identified by Jane Livingston as "a loosely defined group of photographers who lived and worked in New York City during the 1930s, 1940s and 1950s" and who, although disinclined to commit themselves to any group or belief, "shared a number of influences, aesthetic assumptions, subjects, and stylistic earmarks". Livingston writes that their work was marked by humanism, a tough-minded style, photojournalistic techniques, the influence of "film noir" and the photographers Lewis Hine, Walker Evans, and Henri Cartier-Bresson; and that it avoided "the anecdotal descriptiveness of most photojournalism" and the egoism of American action painting, and indeed that it was remarkably little influenced by contemporary painting or graphic design (even though a number of its exponents had direct experience of these). Livingston selects as key exponents of the New York school of photography Diane Arbus, Richard Avedon, Alexey Brodovitch, Ted Croner, Bruce Davidson, Don Donaghy, Louis Faurer, Robert Frank, Sid Grossman, William Klein, Saul Leiter, Leon Levinstein, Helen Levitt, Lisette Model, David Vestal, and Weegee.
Document 7: Michael Abramson: Michael Abramson (1948–2011) was a Chicago photographer who produced a large body of artistic and commercial photography. He earned a Bachelor's degree from the Wharton School of Business, but his life took a different direction when he was accepted at the Institute of Design at the Illinois Institute of Technology in Chicago, and subsequently earned a Masters in 1977. His thesis, "Black Night Clubs of Chicago's South Side," was a reflection and analysis of the photographs he took of patrons and performers in nightclubs on Chicago's south side during the mid-1970s. Abramson's work has often been compared to the 1920s Paris photographer Brassaï (1899-1984). Many of Abramson's south side prints were later published in a photography book / 2 LP record set entitled "Light on the South Side" (2009), by Chicago music recording company Numero Group. The collection of music featured on the LPs are blues songs by mostly Chicago recording artists, and reflect what was actually playing on the jukeboxes in these clubs at the time. A slideshow was created using Abramson's photographs and the music from the LP.

Stefanko will be releasing a book in November of 2017, entitled "Bruce Springsteen: Further Up the Road" that chronicles the 40-year working relationship between himself and Bruce Springsteen.

The work documents the lives of impoverished tenant farmers during the Great Depression. Although it is in keeping with Evans' work with the Farm Security Administration, the project was initiated not by the FSA, but by "Fortune Magazine".

Document 12: Ashcan School: The Ashcan School, also called the Ash Can School, was an artistic movement in the United States during the early 20th century that is best known for works portraying scenes of daily life in New York, often in the city's poorer neighborhoods.
