Lois Greenfield (born April 18, 1949) is an American photographer best known for her unique approach to photographing the human form in motion. Born in NYC, she attended Hunter College Elementary School, the Fieldston School, and Brandeis University. She majored in Anthropology and expected to become an ethnographic filmmaker but instead she became a photojournalist for local Boston newspapers. Her career path changed in the mid 1970s when she was assigned to shoot a dress rehearsal for a dance concert. She has since specialized in photographing dancers not in performance, but in her photo studio as part of her exploration of the expressive potential of movement. She has created countless classic images for the world’s most well known dance companies such as Alvin Ailey, Martha Graham, Merce Cunningham, Paul Taylor, Bill T Jones/Arnie Zane, and American Ballet Theatre. Her work has been published in countless periodicals, and has been exhibited in museums and galleries around the world. Based in New York City, she gives workshops and lectures in schools around the world.
Beginning of Career
In the mid-1970s, Greenfield began what would become avery influential, twenty-year relationship with The Village Voice photographing dance companies reviewed by dance critic Deborah Jowitt for her weekly column. This led to assignments from newspapers and magazines around the world. Around this time she had the opportunity to interview and write about many photographers whom she admired. Among her subjects were Jacques Henri Lartigue, André Kertész, and Duane Michals, who along with photographer Max Waldman were her biggest inspirations.
Rehearsal to Studio
By the late 70’s, she became dissatisfied with a documentary approach to dance photography,which she considered to be merely capturing someone else’s art form. This led Greenfield to discover what would become her own visual syntax.
In 1980, she set up a studio where she invited her subjects to improvise, and together they explored high–risk and non-repeatable moments that could only be seen as a photograph. She created moments expressly for the camera, exploiting photography’s ability to slice time into 1/2000 of a second, revealing to the viewer what the naked eye can’t see. Greenfield describes her use of the medium format Hasselblad camera and how it influenced her:
"In my early work, I used the black frame (the negative's actual border), to interact dramatically with my subjects. Their improvisations play off the frame as though it were a real container. The frame often confines or radically crops them to imply entrances, exits and off-screen space." -Lois Greenfield 
Greenfield developed a radical way of photographing movement. Her dancers appear weightless, freed from the constraints of gravity and locked together in seemingly impossible configurations. The more incomprehensible the picture looked,the more successful it was in Greenfield’s eyes: "What intrigues me is making images that confound and confuse the viewer, but that the viewer knows, or suspects, really happened [...] I can't depict the moments before or after the camera's click, but I invite the viewer's consideration of that question." 
The fruits of these seminal collaborations are documented in her first two books:

Since these early experiments, her photographic method has stayed pretty much the same - shooting just one moment out of a phrase of movement, and never digitally compositing the dancers’ positions in the frame. All her photographs are literal documents, taken as single in-camera images. According to Samantha Clark, "The most interesting moments are the ambiguous ones when you really don't know what is happening or why. The buoyant images in Greenfield's art might have even fooled Galileo, Newton and Einstein." 
Commercial clients picked up on the metaphoric nature of Greenfield’s imagery, and commissioned her to create campaigns. Her most recognized commercial assignment was the groundbreaking series of advertisements she created for Raymond Weil watches in 1993, which appeared for years on billboards and ads worldwide. Since then, her photos and videos have been featured in campaigns for Sony, Disney, Rolex, Hanes, Pepsi, Johnson & Johnson, Epson, and Kodak, among others.
Since the mid-1990s, Greenfield has been fascinated by non-traditional forms of photographic presentation. Invited to participate in “le Printemps de Cahors” in France in 1994, she projected her images onto a 30-foot high water screen in the Lot River. Set against the night sky, Greenfield’s monumental photos seemed to magically appear, then slowly disappear. The propulsion of the water turned her crystal sharp photographs back into flowing moments, making the live experience seem like a product of the imagination.
She pioneered the use of live photography as an integral part of a dance performance. Greenfield collaborated from 2003 to 2007 with the Australian Dance Theatre on HELD, a dance inspired by her photography. Greenfield was onstage shooting the live action, and her images were projected on the stage in real-time. The dance and its representation appeared virtually simultaneously as part of the performance. This award-winning dance was performed to sold-out audiences around the world, from the Sydney Opera House to Sadler’s Wells in London, the Joyce Theater in NYC and Theatre de la Ville, Paris.
Since her first show at New York City’s International Center of Photography in 1992, her work has been exhibited in museums and galleries such as the French Foundation of Photography, the Musee de L’Elysee in Lausanne, the Tel Aviv Art Museum, the ERARTA Contemporary Museum in St. Petersburg, and the Venice Biennale. Her exhibitions have also been very popular with international art and dance festivals, such as the Nordic Light Festival, Jacob’s Pillow Festival, Pingyao Festival, Biennale de la Danse, Melbourne Arts Festival, The New Zealand Festival of the Arts, and Cali Arts Festival.
