kuvanäkökulma

Kuvanäkökulma, also known as the angle of view or field of view, refers to the extent of the observable world that is seen at any given moment. It is a critical concept in photography, cinematography, and computer graphics, as it determines how much of a scene is captured within the frame. The angle of view is typically measured in degrees, with a wider angle of view capturing more of the scene and a narrower angle capturing less.

In photography, the angle of view is influenced by the lens used. Wide-angle lenses have a large angle of view, often exceeding 60 degrees, and are used to capture expansive landscapes or interiors. Telephoto lenses, on the other hand, have a narrow angle of view, typically less than 60 degrees, and are used for capturing distant subjects or compressing the background.

In cinematography, the angle of view is also influenced by the lens and the camera's position relative to the subject. A wide shot, for example, captures a large area of the scene and is often used to establish the setting. A close-up shot, on the other hand, captures a small area of the scene and is often used to focus on a specific detail or emotion.

In computer graphics, the angle of view is determined by the camera's field of view setting, which is typically measured in degrees. A wider field of view results in a more immersive experience, while a narrower field of view results in a more focused experience.

The angle of view is an important consideration in all these fields, as it can significantly impact the viewer's experience and the overall aesthetic of the image or scene. Understanding and controlling the angle of view is a key skill for photographers, cinematographers, and computer graphics artists.
