How does photography shoot real people?

The effect of virtual reality is actually the effect of small depth of field. There are three main factors that determine the depth of field: 1. Aperture; 2. focal length; 3. Shooting distance.

(1) The larger the lens aperture (the smaller the number after f/), the shallower the depth of field; Conversely, the greater the depth of field.

(2) The longer the focal length of the lens, the shallower the depth of field; Conversely, the greater the depth of field.

(3) The closer the shooting distance, the shallower the depth of field; Conversely, the greater the depth of field.

Knowing the above three points, we know that the key to getting a small depth of field is to shoot close to the subject with a large aperture and long focal length lens.
