What rules does the camera's focusing system generally follow to select the focus?

The camera's focusing system has the following rules: single-point focusing, dynamic area focusing, automatic area focusing and so on.

1, single focus

This choice is suitable for situations where the subject is stationary or moving slowly and its position is relatively fixed, such as scenery, still life, portrait and so on. Under this option, we can specify a focus and let the camera focus only on this position. This can ensure that we can take clear and sharp photos, and we can freely control the composition and visual center of gravity of the picture.

2. Dynamic area focusing

This choice is suitable for situations where objects move rapidly or irregularly and their positions are constantly changing, such as sports, animals, airplanes, etc. Under this option, we can specify a main focus point, so that the camera can automatically adjust other focus points nearby for auxiliary tracking according to the moving direction and speed of the subject.

3, automatic area focusing

This choice is suitable for situations where the number of subjects is large or widely distributed, and the location is uncertain or unpredictable, such as crowds, flowers, starry sky, etc. Under this choice, we can let the camera automatically select all available focus points and focus according to the nearest or most prominent subject in the picture.

Camera photography skills

One way to add motion to an image is to enlarger lens and keep the camera still while shooting. When panning places vertical motion in the picture, zooming creates a dynamic 3D effect. When you combine zoom with slow synchronous flash, you will get a very remarkable effect.

You may be told that in order to get a really clear image, you need to keep the camera still while shooting, and I don't want to object to this. But sometimes you want a different result. You can move the camera while shooting to add motion to the photo. To achieve this effect, you can translate, rotate and even throw your camera.

Adjust the shutter speed to overexposure, and you can get a bright and burnt image. If you want to shoot colorful objects, please use this technology, because it will provide you with images on bright and charred backgrounds. If you shoot in poor ambient light and you want to illuminate the object with a flash, this technology is your best choice.
