Through adjusting aperture can change depth of field. Big aperture can realize more shallow depth of field, and small aperture realizes deeper depth of field. The result that both gets has very big difference. The ministry branch at the back of this chapter introduces this content in detail.
Another method that dominates depth of field is change camera lens. The distance films the meeting when the boy or girl friend is closer gets more shallow depth of field, and be far from film the meeting when the object gets deeper depth of field. Same, telephoto lens (or the biggest scorch on camera) because focal distance is very long, depth of field is so more shallow, and wide-angle lens because focal distance is very short, depth of field is so deeper.
Still need to remember additionally, pair of anxious limits of focal around not be equal. About the depth of field of 1/3 is before the focus, the depth of field of 2/3 is after the focus.
4, choice extensive role and telephoto lens
