Les Carnets du BAL is a series set up to work on what is at stake in the contemporary image and to take the notion of the visual document in all its variety. Each subject brings together theoretical contributions and presentations and readings of works by artists, philosophers, historians, anthropologists and critics, drawing on examples from photography, video and cinema. The seventh volume is on the geopolitical uses of images: what states, armies, institutions and artists do with them, and what those uses produce. From the seminar held at the EHESS.
