Tilt-shift photography, also known as tilt-shift photography, was a photography method that used a shift-shift lens to create a work. The characteristics of shift-lens photography were closely related to the characteristics of shift-lens. The most notable feature of the shift-axis lens was that it could shift, tilt, or rotate the main optical axis of the entire photographic lens while maintaining the position of the camera body and the film plane, thereby adjusting the perspective relationship of the photographed image or achieving full-area focusing. The reference clear image field was larger to ensure that the main optical axis of the lens could still obtain a clear image. It was also known as the "TS" lens ("TS" is the English "tilt and shift"),"oblique lens","shift lens" and so on. The main functions of shift-lens photography were as follows: 1. Correct perspective distortion: Reflect clearly in architectural photography. For example, when using a wide-angle focal length lens to shoot the shape of a building, the lines of the building's shape would converge upward due to the perspective effect of the near and far. However, when using a shift-axis lens to shoot, it could rely on its perspective adjustment function to correct this line convergence phenomenon, so that the building remained vertical in the picture, avoiding the feeling of tilting or even tilting. 2. [Realization of regional focus: Commonly used in commercial photography for product advertisements.] By combining the pan and tilt shooting functions of the lens, while correcting the perspective distortion of the subject, it can achieve a full-area focusing effect that is difficult to achieve with ordinary photographic lenses, so that the subject near and far in the picture can form a clear image. The photos and videos taken by the shift-lens photography were like miniature models, which could fully express the feeling of a "man-made city", which was unique and interesting. After using the shift-axis photographic lens on the 35mm single-lens reflex camera, it could be equipped with the function of a large-scale combined camera to control the perspective by adjusting the leather cavity, thus expanding the scope of use of this camera. It played a major role in the field of professional photography. For example, Canon's 135mm system's original, most widely used shift-axis lens, the ts-e 17mm4L, was regarded as an artifact. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The Shifting Flower Palace's sword art was a unique sword art. When it was performed with a narrow sword, the changes of the sword art were like flying clouds, light and graceful. This unique sword art added a mysterious and magnificent color to the Shifting Flower Palace.

If you use a Canon camera for shift-axis architectural photography, there are the following points: ** 1. Scene-related ** 1. ** Screen Selection ** - For example, the Canon TS-E 17mm f/4L lens could be used for shift-axis architectural photography. Its biggest feature was that the angle of view could be shifted without any distortion, and the image quality was excellent. - Canon also had a patent announcement related to autofocus shift-axis lens. The newly designed Canon RF-mount autofocus shift-axis lens was expected to be unveiled in the next release window. It was likely to include autofocus, auto-pan, phase focus, and hand-held shift-axis/pan functions. It was expected that there would be substantial news released before the end of this year. 2. ** Shot operation (Take some shots as an example)** - For some Canon lenses, manual focus was required to set the focal point to infinity when taking a building shift camera. However, Canon lenses had their own special operation. For example, after turning the lens focus ring to the scale infinity, Canon's lens may have to be turned back a little. Using Canon lenses to focus to infinity was difficult to control. It required a few more attempts and test shots to determine accurate focus. ** 2. Shooting parameters setting ** 1. ** Viewing parameters ** - In terms of focal length, 17mm could be used to shoot buildings. When the camera was moving to shoot the buildings, it was necessary to avoid the situation where the buildings were large near and far away, and the bottom was large and the top was small. 2. ** Virtual and real parameters ** - In terms of aperture, for example, when shooting star trajectories (some of the principles are similar to architectural photography, which can be used as a reference), if there is a situation where the city's light pollution is serious and you don't want the building to be too bright (too bright will be unreal), you can choose a relatively small aperture, such as f/4 (using the maximum aperture of a 17mm shift-axis lens as an example). - In terms of sensitivity, there was no need to set it too high. As long as it met the shooting requirements, it would be fine. Using a low sensitivity could obtain a relatively good image quality, such as the setting principle of 400 (referring to the star orbit shooting). 3. ** Exposing parameters ** - The exposure time needed to be adjusted according to the specific situation. For example, if there was light pollution or if the building was too bright, the exposure time should not be too long, such as 20 seconds (reference star orbit shooting). ** 3. Shooting precautions ** - When shooting buildings, if you needed to look up to shoot tall buildings, in order to make the buildings appear neat, the shift-axis lens was a better choice, because the post-processing to correct the building's distortion would cause a serious deterioration in the quality of the image. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
