Lily Keber got her start in filmmaking in Athens, Georgia while taking Jim Herbert's famed Super 8 class. To further her training in the filmmaking process, she spent the summer of 2004 interning at the International Film and Television workshops in Rockport, ME. This provided classroom and hands-on instruction in both narrative and documentary film process while working in 16mm and digital formats. Lily's first taste of teaching came as a teacher's assistant for Chandler Griffin's 7 week youth filmmaking workshop.

After graduating the University of Georgia with a BFA in Fabric Design and Film Studies, Lily spent the summer of 2005 learning filmmaking hands-on in Europe. She interned in the Kodak Pavilion at the Cannes Film Festival and served as post-production assistant on the award-winning Bollywood film The Rising.

Lily continued to hone her filmmaking and teaching skills at the acclaimed media collective Appalshop. She worked closely with Mimi Pickering, the award-winning documentary filmmaker and Guggenheim-recipient whose film The Buffalo Creek Flood: An Act of Man has been selected for the National Film Registry. In addition to production work, Lily spent several semesters serving as audio and video trainer with the NEA-sponsored Appalachian Media Institute. In 2006, she co-lead the Community Media Initiative's Digital Storytelling Workshop in Tallulah, La.

In the fall of 2006, Lily relocated to her new home of New Orleans, La. She assisted director Lauren Thompson on the feature-length documentary N.O. Justice, which examines drug policy, rehabilitation and recidivism rates in Louisiana's criminal justice system. She shot second camera on Luisa Dantas' Land of Opportunity: The New New Orleans and Turkey Creek, Leah Mahan's chronicle of the Biloxi community's struggle for land and water rights. 

In the summer of 2007, Lily's turned her lens to the Department of Homeland Security's policy of family detention. Along with partner Matthew Gossage, Lily shot and edited Hutto: America's Family Prison and created the first blog devoted to this policy. The film and the blog remain the central source of information on family detention, and are still being used as tools by activists nationally.

In the spring of 2008, Lily began work as the media trainer and technical coordinator on The VideoVoice Collective's first New Orleans project. Co-sponsored by ReachNOLA and the Rand Corporation, VideoVoice is a public health initiative designed to "put digital video cameras in the hands of those who know their communities best, assisting them in communicating their ideas and visions." Over the course of the spring and summer, Lily trained eight adult members of the New Orleans community to be documentary directors and producers. The resulting film In Harmonypremiered at the Ashe Center and has since been used as a public-health advocacy tool.
Lily continues balance her personal documentary work with her belief in the democratizing power of community media. As of spring 2009, she is in pre-production on her first feature-length documentary and leading a 3-month documentary workshop with the after-school girls' mentoring program The Awesome Girls. She also is the organizer of The New Orleans Documentary Night (NODOC).
