How to shoot shallow depth of field

You can easily take a shallow depth of field with a large aperture. A large aperture doesn't mean you have to have a lens with an aperture of f/ 1.4 and f/ 1.8. Even a suit lens with a maximum aperture of f/3.5 can do the other two elements. Try to turn the aperture to the maximum.

Step 2 Use telephoto end

Assuming the same aperture value, using telephoto can make the depth of field shallow, such as: lens A: using aperture f/4, 50mm focal length; Lens b: use aperture f/4, 200mm focal length. At this time, the depth of field of lens B will be shallower than that of lens A, and the background will be more blurred.

3. Distance ratio of camera, subject and background

This practical application means that the camera is as close as possible to the subject and the subject is as far away from the background as possible. In this way, even if the same aperture value and focal length are used, the background of the photos taken in this way will be more blurred.
