This book presents three interrelated essays about cinematography which offer a theoretical understanding of the ways that film practitioners orchestrate light in today's post-digital context. Cinematography is a practice at the heart of film production which traditionally involves the control of light and camera technologies to creatively capture moving imagery. During recent years, the widespread adoption of digital processes in cinematography has received a good deal of critical attention from practitioners and scholars alike, however little specific consideration about evolving lighting practices can be found amongst this discourse. Drawing on new-materialist ideas, actor-network theory and the concept of co-creativity, these essays examine the impact of changing production processes for the role and responsibilities of a cinematographer with a specific focus on lighting. Each essay advances a new conceptual perspective on the discipline, moving from the notion of light as vision to light as material, from technology as a tool to technology as a network, and from cinematography as an industry to cinematography as a collaborative art.
