In relation to rack focus, when depth of field is shallow, the technique becomes more noticeable.

• A. It becomes negligible
• B. It becomes less noticeable
• C. It becomes more noticeable
• D. It has no effect on perception

Answer: (C)

Rack focus relies on shifting sharpness from one subject to another within a single frame. When depth of field is shallow, only a small range is in focus, so changing focus between a near subject and a distant subject creates a pronounced change in what’s sharp. That sharp jump draws the viewer’s eye and makes the move feel intentional. If the depth of field were deeper, many elements would stay sharp, so the same focus shift would be far less noticeable. Hence, it becomes more noticeable.
