What are the necessary skills for a photographer?

When the depth of field is very shallow, the focus is a thin plane that falls on the object, parallel to the plane where the photosensitive elements in the digital camera are located. When the conditions affecting the depth of field change, such as the narrowing of the lens aperture, this obvious clarity will begin to extend to the front and back of the lens focal plane. By controlling the depth of field, the photographer can control the clarity of the main body of the picture and the background environment.

In photography creation, if you want to control the depth of field easily, you must understand three main factors that affect the depth of field:

The size of the aperture when shooting The larger the aperture, the smaller the aperture value and the deeper the depth of field. The smaller the aperture, the larger the aperture value and the deeper the depth of field.

The greater the focal length of the lens, the shallower the depth of field; The shorter the focal length; The deeper the depth of field.

The closer the camera is to the shooting distance, the shallower the depth of field; The farther the camera is from the subject, the deeper the depth of field. Tip: The aperture range is closely related to the performance of photographic equipment. A high-quality lens can set a larger aperture range, especially a larger maximum aperture, which can achieve more flexible depth of field control.

How deep the depth of field a particular photo should use depends on the information the photographer wants to convey. How to control the depth of field of a photo is to blur the background, highlight the subject, make the subject more obvious, give people an imaginary space and create an artistic beauty.
