Honing the Visual was a conference organized by the Center for Global Communcation Studies at Annenberg on January 28-29, 2016. It brought together academics, human rights practitioners, journalists, filmmakers and policy makers to examine the interplay between visuals and human rights. It sought to address how, under which circumstances, and to what ends visual technologies and platforms shape the recognition and restitution of human rights claims. In this video, Claire Wardle (Gr'04) of the Tow Center for Digital Journalism at Columbia University gives a workshop on authenticating and verifying eyewitness video, which is now proliferating in the age of smartphones and social media. She is introduced by Annenberg Doctoral Student Opeyemi Akanbi.
