What action increases the focal length in camera work?

• A. Panning
• B. Zooming
• C. Tilting
• D. Tracking

Answer: (B)

Zooming increases the focal length in camera work because it involves adjusting the lens to either bring the subject closer or push it further away. When you zoom in, the effective focal length of the lens increases, allowing you to magnify distant subjects and capture more details from afar. This adjustment alters the perspective and field of view, making it a powerful tool for filmmakers and photographers to control composition and emphasize particular elements within a scene. On the other hand, actions such as panning, tilting, and tracking involve moving the camera itself rather than changing the lens characteristics. Panning is the horizontal movement of the camera, tilting is the vertical movement, and tracking involves moving the camera physically along with the subject. None of these techniques directly affects the focal length of the lens, which is why they are not the correct answer in this context.
