Explain the difference between focal length, perspective, and field of view.

• A. Focal length is a property of the lens; Perspective is the apparent spatial relationship created by camera position; Field of view is how much of the scene is captured.
• B. Focal length is the distance to the subject; Perspective is exposure; Field of view is the frame rate.
• C. Focal length determines brightness; Perspective is the subject's mood; Field of view is the color space.
• D. Focal length controls depth of field exclusively; Perspective is audience perception; Field of view is the sensor size.

Answer: (A)

Focal length is a property of the lens that describes how strongly it magnifies or compresses the scene, determining how wide or telephoto the shot appears. A shorter focal length gives a wide angle of view and more dramatic depth, while a longer focal length magnifies distant subjects and narrows the visible area.

Perspective is about how depth and the spatial relationships between objects read in the frame, and it’s created by where you place the camera relative to the subject. Moving the camera changes perspective because you alter the relative distances between objects; changing the lens can change magnification but doesn’t by itself produce a new sense of depth if you don’t change position.

Field of view is how much of the scene is captured in the frame, governed by both the focal length and the sensor size. A wider field of view captures more of the scene, while a narrower field of view captures less.

So, the best description is that focal length is a lens property, perspective comes from camera position and how it shapes spatial relationships, and field of view is the portion of the scene you capture.
