The scene from Blow Up (1966) contained a lot of movement; both actors and camera were constantly moving. A scene like this would have taken on location rehearsals prior to the shooting date with both the actors and the camera operator to ensure they both match and work in sync on the day as pacing is very important in this scene. Antonioni would have had to clearly communicate with both the actors and the camera operator and DOP both in rehearsals and on the day of shooting to achieve this scene as there are a variety of camera movements including  dolly shots, panning and tilting.
