The Lighting Technician

The job of the lighting technician is to choose the correct type of lights (i.e. incident light) and to arrange them to create the required reflected light for the camera(s). This may require the use of special reflective surfaces and/or the manipulation of various elements within the scene.

In settings such as a studio or theatre, the lighting technician may operate a lighting console, much as a sound technician operates the sound desk.

If you don't have a dedicated lighting technician, then the camera operator will probably take on this responsibility.
