Excuse me, how was this photo taken? Make a physical model. Please don't talk about using SLR, ask for specific methods. thank

Tilt-shift photography refers to the works created through the shift lens, and the photos taken are as special as miniature models. The function of shift lens was originally used to correct the perspective problems caused by ordinary wide-angle lens, but it was later widely used to create photographic works that changed the focus position of depth of field. Moving mirror photography is to make the real world fake and make the photos fully show the feeling of "artificial city".

The main feature of axis-shifting camera lens is that the main optical axis of the whole camera lens can be translated, tilted or rotated on the premise that the plane position of the camera body and the film remains unchanged, so as to adjust the perspective relationship of the shot image or focus the whole area. The reference clear image field of the camera lens with shifting axis is much larger, which is to ensure that the main optical axis of the camera lens can still get a clear image after translation, tilt or rotation. Axis-shifting photographic lens is also called "TS" lens ("TS" is English "Tilt &；; The abbreviation of "shift", namely "oblique shift"), "oblique beat", "shift beat" and so on.

After the 35mm single-lens reflex camera adopts the shifting camera lens, the single-lens reflex camera also has the function of controlling the viewing angle by adjusting the leather cavity of the large-scale combined camera, thus expanding the application range of the 35mm single-lens reflex camera. In the field of professional photography, the lens of shifting axis camera plays a considerable role.

The lens of shift axis camera has two main functions: one is to correct the perspective deformation of the subject; The second is to focus on the whole area of the subject, so that the far and near subjects in the picture form a clear image. Axis-shifting lens is widely used in architectural photography. When shooting the shape of a building, a camera lens with wide-angle focal length is often used. However, due to the perspective effect of wide-angle lens, the lines of architectural modeling converge upward. When shooting the shape of a building with an axis-shifting camera lens, this line convergence phenomenon can be corrected by the angle adjustment function of the lens, so that the building in the picture does not have the usual inclination or even looks like it is going to fall down, but it still appears very vertical. Shift-axis lens can eliminate perspective distortion, because when shooting tall buildings, the lens needs to be tilted upward to get a panoramic view. Results The film plane is at a certain angle with the main line of the high-rise building, and the upper part becomes smaller due to the long distance between objects, resulting in perspective deformation. After the axis-shifting lens moves, the center of the lens does not pass through the center of the film, so the distance between the upper and lower parts of the film to the center of the lens is not equal. Although the upper object distance is far, the corresponding image distance of the lower part is also far, and the corresponding magnification change offsets the perspective deformation. As long as the film plane is parallel to the main line of the building, there is no perspective deformation in the photos taken. It is equivalent to shooting with a large camera (such as 120 camera) with the same focal length lens (wider angle) and then cropping to 135 frames. Shift-axis photographic lenses are also often used to take photos with full area focus. In commercial photography, the translation and tilt shooting functions of this lens are often used in combination, which can correct the perspective deformation of the subject and obtain a full-area focusing effect that is difficult to achieve with ordinary photographic lenses.
