What's wrong with the image of the photography building?

If the line is bent, it is caused by distortion. Because wide-angle lenses are usually used to shoot buildings, barrel distortion is easy to occur in wide-angle lenses, and the distortion of lower-quality lenses will be more serious.

Solution:

1. Don't use the maximum wide angle. The wider the viewing angle, the more serious the distortion. As long as the focal length is reduced by a few millimeters, the distortion can be effectively improved.

2, don't let the building near the edge of the picture, the closer to the edge, the more serious the distortion.

3, the use of high-quality lenses, you can consider a fixed-focus lens, cheap. Anyway, the building is a still life, so you can compose slowly, and it is not troublesome for the focus.

4. Later, it will be corrected by software, but the image quality will inevitably be lost.

If the vertical line is inclined, it is caused by the perspective principle, and the solution is as follows:

1. Long-distance shooting and flat angle shooting can minimize the deformation (but it is impossible to completely eliminate it). Maybe this is not the composition you want.

2. Using shift lens (PC lens) and changing perspective mode can perfectly correct the tilt. But this is a very professional architectural photographic equipment, which is expensive.

3. Later, it is corrected by software, but the image quality will inevitably be lost.
