The larger the focal length, the shallower the depth of field, and the larger the subject.

The larger the aperture, the shallower the depth of field, and the more light entering per unit time.

The farther the shooting distance is, the smaller the distortion is, and the closer the shooting distance is, the greater the distortion is, and the composition method that is separated from the background is the most commonly used.
