From YouTube:
In this video, photographer and Moving Walls exhibition co-curator Susan Meiselas discusses documentary photography’s potential to connect and move audiences by “expanding the circle of knowledge” about human rights and social justice issues.
The video also features a variety of work by photographers supported by the Open Society Institute Documentary Photography Project. The project funds photographers who go beyond documentation, using images to foster civic engagement, organizing, advocacy, outreach, public awareness education, and media attention.

Thanks for sharing, what a great piece. This video really helps me a lot as a new photographer with a hope to become a photojournalist. Once again, thanks for the upload.
