Don't come unless you are a master. How to control depth of field in photography?

1, shooting scenery: When shooting scenery, it is mostly required to shoot clearly before and after, and the maximum depth of field is required. There are usually three focusing methods:

According to hyperfocal distance's principle, if a 28mm lens is used, the full-frame camera is defocused by 0.036mm, the aperture F22 is infinite, and the hyperfocal distance is 1 m, that is, all the scenes except 1 m are clear.

With a wide-angle lens such as 28mm and F22, if you focus 4 meters, the scenery beyond 0.7 meters will be clear.

Clear foreground method: focus the foreground with the minimum aperture, press and hold the preview button of depth of field, turn the focus ring far away with eyes on the foreground until the foreground begins to empty, and then turn the focus ring back until the foreground becomes solid again and the focus is over.

2. Portrait shooting: generally blur the background.

Aperture F 1.4: shallow depth of field;

Chest circumference: f 2.8 ~ 3.5

Five senses: F4~5.6

Taking big photos with the aperture F 1.8~2 and focusing on the eyes can make other parts of the model's face very soft.

Step 3 take a macro

When the object distance is very close, the maximum depth of field is obtained with the minimum aperture. For example, the lens 105mm, F22, the object distance is 0.2m, and the depth of field is only 0.28mm.

When the object distance is medium, such as taking a flower, 105mm lens, the object distance is 0.6m, F22 is used, and the depth of field is 4.4 mm ..

When shooting distant objects, make full use of the preview function of depth of field to determine the appropriate aperture.

These are some techniques. If you want to master the depth of field, you must know the principle and related concepts of depth of field, and then you must shoot more and practice more.
