Principle of pitch connecting plate for moving shaft of middle frame

In fact, the principle of shifting the axis and pitching the middle frame is because the depth of field of the picture is extremely shallow, which makes us feel like shooting a model with a macro lens.

In fact, we all know that when shooting the whole street, the whole building and other places, it is not easy to create a shallow depth of field if you use a wide-angle lens or stand at a high and far place to shoot.

Shifting the mirror or lens baby lens will cause this effect, because the lens can move and swing. For example, LENSBABY can move the front end of the lens, change the angle at which light is projected to the photosensitive element, and skew the plane, so even the scenery on the same plane can easily create a shallow depth of field.
