angle of view

Thân thiện

A photographer adjusts the angle of view on their camera.

Definition

Noun: - The angular extent of a scene that is captured by a camera lens or seen by the eye: It is the angle between two imaginary lines drawn from the lens to the extreme edges of the field that can be recorded or observed.

Usage

• This term is used primarily in photography, optics, and cinematography to describe how much of a scene a lens can capture.
• A wider angle of view captures more of the scene, while a narrower angle of view captures a smaller, more magnified portion.

Examples

• Noun:
  • A wide-angle lens has a very large angle of view, perfect for landscapes.
  • When choosing a lens, consider the angle of view to ensure it fits your compositional needs.
  • The human eye has an angle of view of approximately 120-140 degrees.

Advanced Usage

• "Field of view (FOV)": While closely related, "field of view" typically refers to the linear or angular extent of the observable world seen at any given moment, whereas "angle of view" specifically describes the angular measurement. In photography, they are often used interchangeably.
  • The angle of view of this security camera is 90 degrees, giving it a wide field of view.

Variants and Related Words

• Field of View (FOV) (noun): The extent of the observable world that is seen at any given moment or through an optical device.
• Focal Length (noun): The distance between the lens and the image sensor. It is inversely related to the angle of view; a shorter focal length gives a wider angle of view.

Synonyms

• Viewing angle
• Angular field

Related Technical Terms

• Wide-angle: Describes a lens with a large angle of view (typically 60° or more).
• Telephoto: Describes a lens with a small angle of view (typically 30° or less), providing magnification.
• Normal lens: A lens with an angle of view that approximates that of human vision (typically around 40-55°).
