Use the distance between the subject and the background to control the depth of field. The distance between the subject and the background of industrial high-speed cameras is very close, and the shallow depth of field effect is difficult to show: when the subject and the background are very far away, even if the telephoto lens is matched with a large aperture, it is difficult to virtualize the background. Subjects should be as close to the subject as possible, and subjects should be kept as far away from the background as possible. In this way, the effect of the virtualized background is more obvious.
Apply the principle that the background depth is greater than the foreground depth. In photography practice, the photographer should make full use of the front and rear depth of field according to the formation characteristics of the depth of field. Often, they can take full advantage of the depth of field by choosing a focal point.
