What is tilt-shift photography?

Answer: 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 take pictures of the real world as if it were a fake, so that the photos can fully express the feeling of the "artificial city"! A tilt-shift photography lens is a photography lens that can adjust the perspective relationship of the photographed image or focus on the entire area . The main feature of a tilt-shift photographic lens is that it can translate, tilt or rotate the main optical axis of the entire photographic lens while maintaining the same position of the camera body and film plane, so as to adjust the perspective relationship or full range of the captured image. The purpose of regional focus. The reference clear image field of a tilt-shift photographic lens is much larger. This is to ensure that a clear image can still be obtained after the optical principal axis of the photographic lens is translated, tilted or rotated. Tilt-shift photography lenses are also called "TS" lenses ("TS" is the abbreviation of "Tilt&Shift" in English, which means "tilt and shift"), "tilt lens", "shift lens", etc. The use of a tilt-shift photographic lens in the 35mm single-lens reflex camera enables this single-lens reflex camera to also have the function of controlling perspective by adjusting the bellows of a large combined camera, thereby expanding the scope of use of the 35mm single-lens reflex camera. , In the field of professional photography, tilt-shift photography lenses play a considerable role. The tilt-shift photography lens has two main functions. One is to correct the perspective deformation of the subject; the other is to achieve full-area focus on the subject so that both near and far subjects in the picture can form a clear image. . Tilt-shift photography lenses are most commonly used in architectural photography. When photographing the appearance of a building, a photographic lens with a wide-angle focal length is often used. However, due to the perspective effect of the wide-angle lens, the lines of the photographed building's contours converge upward. When photographing the appearance of a building using a tilt-shift lens, you can rely on The perspective adjustment function of the lens corrects this phenomenon of line convergence, so that the buildings appearing in the picture do not have the usual feeling of tilting or even falling over, but still appear vertical. Tilt-shift lenses are also often used to capture images that focus on the entire area. When shooting product advertisements in commercial photography, the pan and tilt shooting functions of this lens are often used in combination to correct the perspective deformation of the subject while achieving a full-area focusing effect that is difficult to achieve with ordinary photography lenses.
