In what ways does the act of filming alter the conditions of fieldwork and shift the epistemological foundations for the production of knowledge? With examples from two very different fieldworks, respectively among peasants in Central France and an Amerindian group in French Guiana, the lecture explores how a filmic approach may create a cooperative frame - a scene - for the production of new insights and knowledge, positioning the fieldworker and creating a particular frame of participation, a participation that will also come to determine the outlines and content of the empirical field.
