"Soft" axis how to use PS to eliminate the tilt effect of the building

Q: I used to take a lot of pictures of high buildings, but these pictures are obviously deformed. The top of the buildings in these photos are converging inward, how can I avoid such a phenomenon in future filming?

A: The most straightforward solution is to spend money on a moving axis lens (also known as a perspective correction lens), but these lenses are very expensive. When using a wide-angle focus lens or a wide-angle end of a zoom lens, stretching the distance between you and the object will help reduce the barrel distortion caused by the wide-angle lens.

To minimize the convergence of the lines brought by large, wide-angle lenses, keep the level of the camera and building flat as much as possible. Find a higher position, which improves the camera's level of shooting, but make sure you get a full picture of the building. Do not under the building, look up to shoot upward, which will lead to obvious building lines converge upward perspective effect.

These intuitive solutions, far from building or taking a high seat, may not be a good way to implement. Fortunately, you can find tools for correcting perspective and lens distortion in most image editing software.
