Lou Dematteis is an American photographer and filmmaker whose work focuses on documenting social, environmental and political conflict and their consequences in the United States and around the world.
He has returned several times to continue this documentation and has most recently focused on the health impacts on the people of the Amazon as a result of Texaco's toxic contamination.
Dematteis's photos have been widely exhibited in the United States and abroad, including showings at the Ansel Adams Center in San Francisco and the Photographers' Gallery in London.
His award-winning documentary Crimebuster: A Son's Search for His Father, which he produced and directed, was shown on Public Television nationwide beginning in June 2012.
It is set in San Francisco's Latino Mission District and addresses the timely issues of fires, gentrification and the displacement of low-income communities.
