Day-to-Day Responsibilities
Studies the script, the blocking and the cinematographer's plan before the shoot begins.
Measures distances from the camera to the subject and marks positions on the floor with tape so the focus can be set accurately.
Adjusts focus on the lens with a follow-focus wheel during rehearsals and takes, often smoothly over the length of a shot.
Pulls focus as actors, vehicles or the camera move, working from a monitor and sometimes with a focus assistant's help.
Checks lens choice, focal length and depth of field with the camera team before each take.
Keeps lenses clean, handles them with care and makes sure the correct lens is ready for each setup.
Communicates with the camera operator, the cinematographer and the director during setups to keep the shot on track.
