Which technique allows for greater focus control during a shot?

Follow focus is a technique that allows operators to adjust the focus of a shot while maintaining a precise control over the focal point, enhancing the cinematographic quality of a video. This is particularly useful in scenes that involve movement or shifting focus between subjects. By using follow focus systems, the camera operator or focus puller can perform smooth transitions between different points in a scene, ensuring that subjects remain sharp and in focus, which is crucial for storytelling and visual clarity.

This technique is especially beneficial in complex shots where quick adjustments to focus are necessary, allowing for a more dynamic and engaging visual experience. The ability to shift focus effectively enhances the narrative by drawing the audience's attention exactly where it needs to be at any given moment. In contrast, the other options do not provide the same degree of control over focus during a shot.
