How to shoot the "follow-up method" in photography?

Follow-up shooting' is also called' follow-up shooting', that is, the camera moves in the same direction with the motion of the subject and shoots during the follow-up process. In the process of shooting, the camera should move at the same speed as the subject, so that the moving object is clear and the background (relatively static ground scenery) is blurred horizontally, which not only highlights the moving subject, but also shows a good sense of movement, and the effect is very good. When shooting, the shutter speed should be 1/50~ 1/60 seconds, and the lens with a focal length of 50~ 100 mm is better; If you use a lens with a focal length of more than 100 mm, it is easy to shake and make the photo unclear. If a lens with a focal length above 100 mm is used, the shutter speed should be1125 ~1/250 seconds. The essentials of tracking shooting are: the lower body should stand firm, the arms should gently clamp the body, the eyes should be fixed on the moving subject in the viewfinder, the upper body should rotate, and the shutter should be pressed while following the subject. You can adjust the focal length by visual inspection in advance, reduce the aperture and increase the depth of field.
