0 basic photography! Understand the depth of field

When taking pictures with a camera, the clear part of the picture is the depth of field, which is also called the clear range before and after focusing.

What is shallow depth of field?

Shallow depth of field brings more obvious background blur effect.

What is a large depth of field?

Large depth of field brings clearer object effects.

The larger the aperture, the shallower the depth of field.

Aperture is the most effective method to control the depth of field.

Aperture magnification has a shallower depth of field and a simpler background, which is suitable for shooting: portrait close-up.

The aperture is reduced and the depth of field is enlarged, and the picture elements are clear, which is suitable for shooting: landscape photos.

The longer the focal length, the shallower the depth of field.

The focal length and shooting distance complement each other, and both * * * affect the depth of field.

The focal length is long, the subject is enlarged, the depth of field is shallow and the background is blurred.

If the focal length is short, use the wide-angle end to reduce the subject, so that the depth of field becomes larger and the background is clear.

The closer the shooting distance, the shallower the depth of field.

The closer the camera is to the subject, the shallower the depth of field, and the more obvious the blur effect.

The farther the distance between the camera and the subject, the greater the depth of field/more details can be captured.

Three-factor formula of depth of field

The larger the aperture, the shallower the depth of field.

The longer the focal length, the shallower the depth of field.

The shorter the shooting distance, the shallower the depth of field.

Background blur effect

Enlarge the aperture, lengthen the focal length and shorten the shooting distance.

Clear background effect

Narrow the aperture, use a wide angle and lengthen the shooting distance.
