Moving Walls 20 is a documentary photography exhibition on human rights, produced by the Open Society Foundations (OSF). The current exhibit highlights societies undergoing transition in China and the Middle East, and people suffering from repressive regimes and injustice in North Korea, Sierra Leone, and Ukraine. The Moving Walls project began in 1998 and has featured more than 170 artists whose works address issues of social justice and human rights. OSF provides grants to participating photographers, whose work is exhibited at the foundation’s New York and Washington, D.C., offices. Interested photographers should check in late 2013 for the next call for submissions.
