This introduction presents an overview of key concepts discussed in the subsequent chapters of this book. The book considers the ethical and power issues invoked in the social research process and outcomes. Just as a sea change is occurring in social research to include participatory visual and digital methodologies, the relevance and social justice potential of ethnography is also reaching policy and activist settings. The book features participatory visual methodology case studies that include photovoice, digital storytelling, participatory geographic information systems (PGIS), participatory forms of digital archival research, and collaborative and participatory film and videomaking. It discusses the ways that ethnographic field methods have been applied in international and community development work, contexts which serve as the wellspring for many of the methods. Finally, The book presents the "core methodology stories" of researcher/practitioners all pioneering scholars in their own right who have used the methods in their work.
