Stephen Callis is a documentary photographer from Southern California interested in how the struggles of land use and development leave their mark on the landscape. He has documented the Los Angeles River and its bridges that connect the city. In 2007, after a brushfire scorched Griffith Park, he documented the devastation of the park. In addition, he has collaborated with labor unions to produce two bilingual (English/Spanish) photonovelas documenting the struggles of janitors and housekeepers trying to unionize.
