Perspective distortion: Difference between revisions

Line 13:

When affecting distance, perspective distortions can make things seem as if they are physically closer or further away than they usually would be. This can range from a subtle experience, such as the other side of the room feeling marginally further away than it usually would be, to an extreme experience, such as feeling as if the horizon is right in front of you.

Perspective distortions are often accompanied by other coinciding effects such as [[depth perception distortions]] and [[visual disconnection]].
