Forced perspective is a technique that employs optical illusion to make an object appear farther away, closer, larger or smaller than it actually is. It is used primarily in photography, filmmaking and architecture. It manipulates human visual perception through the use of scaled objects and the correlation between them and the vantage point of the spectator or camera.
There is a very simple way to preserve the perspective in your pictures. There is only one rule to follow: Always keep your camera perfectly vertical when taking the shot. Keep it perpendicular to the ground, parallel with the front of the building being photographed.
