How does focal length influence perspective and background compression in an image?

• A. Short focal lengths compress perspective; long focal lengths exaggerate depth
• B. Short focal lengths exaggerate perspective and depth; long focal lengths compress perspective
• C. Focal length has no effect on perspective
• D. Long focal length removes background blur

Answer: (B)

Focal length shapes how depth is represented in a image by changing the angle of view. A short focal length uses a wide angle, making objects close to the camera appear larger relative to the background and pushing distant elements farther away in the frame; this exaggerates perspective and boosts the sense of depth. A long focal length narrows the field of view and magnifies distant details, pulling the subject and background closer together in the image and producing a compressed, flatter look. Depth of field and background blur are related concepts but depend on distance and aperture as well; the core idea here is how focal length alters perspective and background compression.
