How does the camera capture the effect of depth of field? Is it related to the camera?

The depth of field refers to the distance range that an object measured along the axis of the imaging depth of field machine can obtain a clear image in front of the camera lens or other imagers.

After focusing, a clear image can be formed in the range before and after focusing, which is called the depth of field.

When the lens of a camera is clearly focused on an object, the points on the same plane perpendicular to the lens axis at the position opposite to the lens center can be quite clear images on the film or receiver, and the points in a certain range before and after the lens axis on this plane can also form relatively clear image points acceptable to the eyes. The distance between all the scenes before and after this plane is called the depth of field of the camera.

Three determinants of depth of field:

1, lens focal length

2, the main distance

3, the size of the aperture

Aperture, the distance between the lens and the subject are important factors affecting the depth of field;

1, the larger the aperture, the smaller the depth of field, and the smaller the aperture, the greater the depth of field.

2. The longer the focal length of the lens, the smaller the depth of field; Conversely, the greater the depth of field.

3. The closer the subject is, the smaller the depth of field is, and the farther the subject is, the greater the depth of field is.
