What is lens shift?

Tilt-shift photography, also known as tilt-shift photography, generally refers to works created using a tilt-shift lens. The effect of the photos taken is like a miniature model, which is very special. The function of the tilt-shift lens was originally mainly used to correct the perspective problems caused by taking pictures with ordinary wide-angle lenses, but later it was widely used to create photography works that change the position of the focus point of the depth of field.

Tilt-shift photography is to photograph the real world as if it were a fake, so that the photos can fully express the feeling of the "artificial city"
