August Sander
(17 November 1876 – 20 April 1964)

Was a German portrait and documentary photographer. Sander's first book Face of our Time (German title: Antlitz der Zeit) was published in 1929. Sander has been described as "the most important German portrait photographer of the early twentieth century."
Straight photography

Pure photography refers to photography that attempts to depict a scene as realistically and objectively as permitted by the medium, renouncing the use of manipulation.
Founded in 1932, Group f/64 who championed purist photography, had this to say:
Pure photography is defined as possessing no qualities of technique, composition or idea, derivative of any other art form.
The term emerged in the 1880s to mean simply an unmanipulated photographic print, in opposition to the composite prints of Henry Peach Robinson or the soft-focus painterly images of some pictorialist photographers. At first, straight photography was a viable choice within pictorialism, as, for example, the work of Henry Frederick Evans. Paul Strand's 1917 characterization of his work as ‘absolute unqualified objectivity’ described a change in the meaning of the term. It came to imply a specific aesthetic typified by higher contrast, sharper focus, aversion to cropping, and emphasis on the underlying abstract geometric structure of subjects. Some photographers began to identify these formal elements as a language for translating metaphysical or spiritual dimensions into visual terms. This emphasis on the unmanipulated silver print dominated modernist photographic aesthetics into the 1970s.
Irving Penn
(June 16, 1917 – October 7, 2009)

American photographer known for his portraiture and fashion photography.

Irving Penn studied under Alexey Brodovitch at the Philadelphia Museum School of Industrial Art (now the University of the Arts) from which he was graduated in 1938. Penn's drawings were published by Harper's Bazaar and he also painted. As his career in photography blossomed, he became known for post World War II feminine chic and glamour photography.
Penn worked for many years doing fashion photography for Vogue magazine, founding his own studio in 1953. He was among the first photographers to pose subjects against a simple grey or white backdrop and used this simplicity more effectively than other photographers. Expanding his austere studio surroundings, Penn constructed a set of upright angled backdrops, to form a stark, acute corner. Subjects photographed with this technique included Martha Graham, Marcel Duchamp, Pablo Picasso, Georgia O'Keeffe, W. H. Auden, Igor Stravinsky and Marlene Dietrich.
Diane Arbus
(March 14, 1923 – July 26, 1971)

American photographer and writer

She was noted for black-and-white square photographs of "deviant and marginal people (dwarfs, giants, transvestites, nudists, circus performers) or else of people whose normality seems ugly or surreal."A friend said that Arbus said that she was "afraid... that she would be known simply as 'the photographer of freaks'"; however, that term has been used repeatedly to describe her.
Franco Vaccari
(Modena, 18 giugno 1936)

Italian photographer

Photographer Franco Vaccari is a pioneer of photobooth art, whose work at the 1972 Venice Biennale is a major work of relational art.
"In 1972 I took part in the Venice Biennale, with a personal exibition space, putting on 'Leave a photographic trace of your passage on these walls,' that saw the participation of more than 5000 paying people.
"A book was published of the material collected in 1973. In the same year I started an initiative titled Photomatic d'Italia, featuring 700 photobooths for one year all over Italy. Later I did similar initiatives in Tokyo and Prague.
"After the aforementioned book, another book titled Franco Vaccari: Photomatic e altre storie was published by Electa. Many other exaustive documentations on the same subject were included in my anthological books published by Damiani and the publisher Baldini, Castoldi, Dalai.
"Many other informations can be found in the book by Federica Muzzarelli Formato tessera-storia arte idee in photomatic."
Hilla and Bernd Becher
German artists

Meeting as painting students at the Kunstakademie Düsseldorf in 1957, Bernd and Hilla Becher first collaborated on photographing and documenting the disappearing German industrial architecture in 1959. The Ruhr Valley, where Becher’s family had worked in the steel and mining industries, was their initial focus. They were fascinated by the similar shapes in which certain buildings were designed. In addition, they were intrigued by the fact that so many of these industrial buildings seemed to have been built with a great deal of attention toward design. Together, the Bechers went out with a large 8 x 10-inch view camera and photographed these buildings from a number of different angles, but always with a straightforward "objective" point of view. They shot only on overcast days, so as to avoid shadows, and early in the morning during the seasons of spring and fall. Objects included barns, water towers, oal tipples, cooling towers, grain elevators, coal bunkers, coke ovens, oil refineries, blast furnaces, gas tanks, storage silos, and warehouses. At each site the Bechers also created overall landscape views of the entire plant, which set the structures in their context and show how they relate to each other.One of their first projects, which they pursued for nearly two decades, was published as “Framework Houses” (Schirmer/Mosel) in 1977, a visual catalog of types of structures, an approach that characterized much of their work.
Martin Parr
(born 23 May 1952 in Epsom, Surrey)

British documentary photographer, photojournalist and collector.

She e is known for his photographic projects that take a critical look at modern society, specifically consumerism, foreign travel and tourism, motoring, family and relationships, and food.
Rineke Dijkstra
(born 1959)

Dutch photographer

Dijkstra concentrates on single portraits, and usually works in series, looking at groups such as adolescents, clubbers, and soldiers. Her subjects are often shown standing, facing the camera, against a minimal background. This compositional style is perhaps most notable in her well-known beach portraits, which generally feature one or more adolescents against a seascape. This style is again seen in her work on pregnant women.
One of her works entitled, Daniel, Adi, Shira, and Keren, Rishonim High School, Herzliya, Israel (1999/2000) consists of two photograghs taken 20 months apart. It evokes questions about the youths' futures and whether they were, are, or will be in uniform.
Her works are held in numerous museum collections, including the Tate and the Museum of Modern Art.

Since 1994, photographer Ari Versluis and profiler Ellie Uyttenbroek have been trekking the globe together, recording Exactitudes — “exact attitudes” captured in people’s peculiar dress code as an attempt to differentiate themselves from others or identify with a group.
Gender Studies
Gender studies is a field of interdisciplinary study which analyzes the phenomenon of gender. Gender studies is sometimes related to studies of class, race, ethnicity, sexuality and location.
The philosopher Simone de Beauvoir said: “One is not born a woman, one becomes one.” In gender studies, the term "gender" is used to refer to the social and cultural constructions of masculinities and femininities, not to the state of being male or female in its entirety.[3] The field emerged from a number of different areas: the sociology of the 1950s and later (see Sociology of gender); the theories of the psychoanalyst Jaques Lacan; and the work of feminists such as Judith Butler.
Each field came to regard "gender" as a practice, sometimes referred to as something that is performative. Feminist theory of psychoanalysis, articulated mainly by Julia Kristeva[5] (the "semiotic" and "abjection") and Bracha Ettinger (the "matrixial trans-subjectivity" and the "primal mother-phantasies"), and informed both by Freud, Lacan and the Object relations theory, is very influential in gender studies.
Taxonomy (from Ancient Greek: τάξις taxis "arrangement" and Ancient Greek: νομία nomia "method") is the practice and science of classification. Taxonomy uses taxonomic units, known as taxa (singular taxon). In addition, the word is also used as a count noun: a taxonomy, or taxonomic scheme, is a particular classification ("the taxonomy of ..."), arranged in a hierarchical structure. Typically this is organized by supertype-subtype relationships, also called generalization-specialization relationships, or less formally, parent-child relationships. In such an inheritance relationship, the subtype by definition has the same properties, behaviors, and constraints as the supertype plus one or more additional properties, behaviors, or constraints. For example: car is a subtype of vehicle, so any car is also a vehicle, but not every vehicle is a car. Therefore a type needs to satisfy more constraints to be a car than to be a vehicle. Another example: any shirt is also a piece of clothing, but not every piece of clothing is a shirt. Hence, a type must satisfy more parameters to be a shirt than to be a piece of clothing.
Ethnology (from the Greek ἔθνος, ethnos meaning "people, nation, race") is the branch of anthropology that compares and analyzes the origins, distribution, technology, religion, language, and social structure of the ethnic, racial, and/or national divisions of humanity.
