In a camera, what does changing the Field of View control?

• A. The angle of view
• B. The camera's position
• C. Depth of field only
• D. Render resolution

Answer: (A)

Field of view determines how wide the camera’s scene appears—the angle of the image that passes through the lens. When you widen the FOV, you capture more of the environment and objects look smaller with more perspective distortion; when you narrow the FOV, the view is zoomed in and perspective is less exaggerated. This is a property of the camera’s projection, not its position—moving the camera changes what portion of the scene you see, but not how wide the scene is captured. Depth of field is controlled mainly by focus distance and aperture, not by FOV, and render resolution is a separate setting that affects pixel count. So the best description is that changing the Field of View controls the angle of view.
