How to shoot the building straight? When shooting a building, it is easy to tilt the house with a wide-angle lens. How to shoot the building straight?

This phenomenon is caused by the perspective deformation of the wide-angle lens, which is caused by the back shot, and the severity of the deformation depends on the distance of the subject. In other words, in order to eliminate this distortion, the fundamental solution is to shoot directly at the building (don't shoot up and down), which requires changing the shooting position (shooting directly at the opposite building) or cutting (far enough away from the building, cutting off the building part after shooting). If the environmental conditions do not allow (the site is not open enough and the nearby buildings are not suitable), then the axis-shifting lens can only be used. The axis-shifting lens is designed to solve this perspective distortion, which will of course be expensive.
