Shifting focus to emphasize a subject at different depths within a single shot is called what?

• A. Rack focus
• B. Demographics
• C. Composition
• D. Slate/Clapper

Answer: (A)

Rack focus is a camera technique where you shift the plane of sharpness within a single shot to move emphasis from one depth to another. By adjusting the lens focus during the take, a foreground subject can go from sharp to blurred while a background subject comes into focus, or vice versa. This guides the viewer’s eye and can reveal relationships or new information without cutting to a different shot. It’s a handy way to show connection between characters at different depths or to change what the audience should notice as the scene unfolds. It requires precise follow-focus work and practice to keep the transition smooth. The other terms aren’t about changing focus during a shot: demographics is about who watches, composition is about framing, and slate/clapper is a marker used to sync sound and organize takes.
