From the advent of the daguerreotype (the first form of photography) in 1839, women have utilized the art form of photography to document and represent the female perspective. Whether you’re a photographer yourself, or a passive supporter of the art, it’s important that we take the time to acknowledge the female photographers who have changed the game.

Fortunately, May is #NationalPhotoMonth, and in honor of this celebration, we’re highlighting eight female photographers and their culturally significant work.

Ms. Cameron is noted for her soft-focus technique, which was actually somewhat shunned while she was still alive for being “bad” photography. Nowadays, however, her emphasis on emotion (which was rarely shown in photographs of that era) sets her work apart. (See Cameron’s photograph entitled, “Sadness.”) Her photographic philosophy?

Yumna Al-Arashi (1988–present)

Al-Arashi is Muslim, and was raised in Washington, D.C. Perhaps her most popular series, “Northern Yemen,” portrays Muslim women as powerful figures against a backdrop of the landscapes of their home country. She told the website Artsy:

Simpson is known internationally for her signature style, which combines graphic text and studio-like portraiture. In the eighties, she became well known for her large-scale works that sought to undermine “traditional conceptions” of identity, sex, culture, race, memory, history, and the like. One of her most lauded projects is “Guarded Conditions.” Sofía Retta writes of the work:

Annie Leibovitz (1949–present)

There is a near 100% chance that you have seen Annie Leibovitz’s work at least once in your lifetime, even if you didn’t realize it. She captured the iconic image of John Lennon naked, curled up next to Yoko, on the day he was assassinated. She got her start at Rolling Stone, contributing to the intimate photographs of celebrities that the magazine became known for. She was also the first woman to have held an exhibition at London’s National Portrait Gallery. Nowadays, she is known for her big-production portraits of celebrities, from Whoopi Goldberg to Queen Elizabeth II. She has said of her work:

Ishiuchi Miyako (1947–present)

When Ishiuchi Miyako was born in Japan in 1947, she was born into a country infiltrated by US servicemen living on the naval bases during the military occupation after World War II. This Western presence deeply affected Ishiuchi’s early childhood, and served as the impetus for her first documentary-like project, “Yokosuka Story.” She said in an interview with Aperture:

Mark is known for photographing and documenting those on the border of society, outside of the mainstream. She usually worked in black and white. 18 (yes, 18) collections of her work were published during her lifetime. Mark once said:

Vivian Maier (1926–2009)

Personally, I find Vivian Maier’s story to be one of the most interesting of any photographer’s. She grew up in both the States and France intermittently, and in her mid twenties and for 40 years of her life, became a nanny for two families: the Gensburgs from 1956 to 1972, and the Raymonds from 1967 to 1973. One member of the Gensburg family described her as a real-life Mary Poppins.

But the most interesting part? Two years before she passed, in 2007, the contents of Maier’s storage space in Chicago (including her negatives, prints, audio recordings, and 8 mm film) were auctioned off because she failed to pay the fees. Three photo collectors bought parts of her work, and began publishing her work *for the first time.* Her archives were both extensive and incredible, and no one knew the extent of her talent until she had passed.

A curator of her work, John Maloof, described Maier by saying:

Neshat was raised in the religious town of Qazvin, Iran. Thus, her work often contrasts Islam and the West, and also explores femininity and masculinity in opposition to each other. One of her most famous works, the “Women of Allah” series, feature portraits of women turned mixed-media with Persian calligraphy. Neshat told BOMB Magazine:
