How can the camera focus to get a clear picture?

Talk about the usage of the four focusing modes of the camera to help you improve the shooting efficiency and the clarity of the photos.

1. What is focusing?

Every photo will have a theme, which is the focus of our performance. We move the focal plane back and forth by adjusting the lens group inside the lens until the subject is clearly presented. This is the process of "focusing".

In the camera, the focus can be achieved through the focus ring, or the camera can complete the focus itself. If it is a mobile phone, the focus can be auto-focus of the mobile phone, or you can click on any area of the screen with your finger to complete the focus at the clicked place.

2. What are the focusing methods?

Focusing methods can be divided into automatic focusing and manual focusing, among which automatic focusing is divided into single automatic focusing, artificial intelligence servo automatic focusing and artificial intelligence automatic focusing, plus a manual focusing method, so there are two categories and four subcategories of focusing methods.

3. Specific application scenarios of four focusing modes

① Single autofocus

When we half press the shutter to focus on the subject, we hear the prompt sound of "di", which means that the camera has finished focusing and achieved focusing, and then we can press the shutter to finish shooting. This focusing mode is suitable for shooting still life subjects, that is, subjects with fixed subjects, such as portraits, landscapes and products. , which can be used for focusing.

② Artificial intelligence servo autofocus

Artificial intelligence servo autofocus can also be called tracking focusing and continuous focusing. This mode is designed for shooting sports themes. For example, shooting sports events, shooting passers-by in a hurry, shooting lively animals and so on all need to use this focus mode. , you can easily focus and improve your shooting efficiency and photo clarity. When using, when we half press the shutter, the camera will focus on the moving subject, and the focus will always follow the subject, so that you can press the shutter button calmly, and the picture is still clear without losing focus at all.

③ Artificial intelligence autofocus

This focusing mode is an "integrated" version of the above modes ① and ②. It will choose autofocus according to whether the subject is moving or still, and shoot the moving subject. It will automatically choose artificial intelligence servo autofocus to shoot a still subject, and it will choose single autofocus, which is highly intelligent, but it is easy to make mistakes when shooting some scenes with obstructions, small picture contrast or close subjects. At this time, you need to choose the manual focus mode to shoot.

④ Manual focusing

When using autofocus mode, sometimes there will be problems in focusing, resulting in out-of-focus and "bellows pulling" phenomenon. For example, when shooting some scenes with obstructions, low contrast or close subjects, the autofocus mode is not satisfactory. At this point, we
