Introduction to photography, depth of field

1. What is the depth of field?

The concept of depth of field: after focusing, the clear image presented in the range before and after focusing. The distance before and after this clear range is called depth of field.

Small depth of field: it presents a more obvious background blur effect with a small clear range.

Large depth of field: presenting clearer object effects and a wider range of clarity.

Second, the larger the aperture, the smaller the depth of field.

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

The aperture is larger, the depth of field is smaller, the foreground background is blurred, and the picture background is more concise, which is suitable for shooting: portrait close-up.

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

Third, the longer the focal length, the smaller the depth of field.

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

Using wide-angle focal length to reduce the subject, the depth of field becomes larger and the background is clear, which is often used to shoot landscapes.

Zoom in and enlarge the subject, the depth of field becomes smaller and the background is blurred, which is often used to take portraits.

Fourth, the closer the shooting distance, the smaller the depth of field.

The closer the camera is to the subject, the smaller 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, and more details can be photographed.

Verb (abbreviation of verb) Summary of three elements of depth of field.

Aperture: The larger the aperture, the smaller the depth of field.

Focal length: The longer the focal length, the smaller the depth of field.

Distance: The closer the distance, the smaller the depth of field.
