Photography skills: How to pursue focus photography?

This technique is simple, but there are several points to note:

1. When the shutter speed is faster than 1/60 seconds, it is not easy to cause a sense of flow because the shutter speed is too fast.

2. When the shutter is slower than 1/4 seconds, the moving lens is likely to cause serious "vertical" hand shake, especially for the camera on the small platform.

3. The movement of the lens must be relatively synchronized with the speed of the moving target, otherwise the imaging will be chaotic.

Because the target is constantly moving, no matter how accurate the focus is in advance, it will be partially out of focus. Therefore, the shooting position should not be parallel to the moving direction of the object as far as possible, and it is best to make an angle of 15~45 degrees with the moving direction. This contrast can increase the retention and opportunity of the clear part (the focused part) and increase the tension of the picture.
