Angle of View is the measurement of how much of a scene a camera lens can capture. It is determined by the focal length of the lens and influences how much of the subject will be included in the final image. A wider angle of view means more of the scene can be captured, while a narrower angle of view focuses on a smaller portion of the scene, resulting in a more zoomed-in look. Understanding the angle of view is crucial in composing shots and controlling the perspective of an image.
