Editing Forced perspective (section)

===In motion===
[[Peter Jackson]]'s film adaptations of ''[[The Lord of the Rings]]'' make extended use of forced perspective. Characters apparently standing next to each other would be displaced by several feet in depth from the camera. This, in a still shot, makes some characters ([[Dwarf (Middle-earth)|Dwarves]] and [[Hobbit]]s) appear much smaller than others. If the camera's point of view were moved, then [[parallax]] would reveal the true relative positions of the characters in space. Even if the camera is just rotated, its point of view may move accidentally if the camera is not rotated about the correct point. This point of view is called the 'zero-parallax-point' (or front nodal point), and is approximated in practice as the centre of the entrance pupil.<ref>{{Cite news|last=Allain|first=Rhett|url=https://www.wired.com/2012/12/how-to-make-a-hobbit-with-forced-perspective/|title=How to Make a Hobbit With Forced Perspective|date=2012-12-04|magazine=Wired|access-date=2020-04-22|issn=1059-1028}}</ref>

An extensively used technique in ''[[The Lord of the Rings: The Fellowship of the Ring]]'' was an enhancement of this principle, which could be used in moving shots. Portions of sets were mounted on movable platforms which would move precisely according to the movement of the camera, so that the optical illusion would be preserved at all times for the duration of the shot. The same techniques were used in the ''[[Harry Potter]]'' movies to make the character [[Rubeus Hagrid]] look like a giant. Props around [[Harry Potter (character)|Harry]] and his friends are of normal size, while seemingly identical props placed around Hagrid are in fact smaller.<ref>{{Cite web|url=https://www.nbcnews.com/id/wbna39080739|title=Size matters: Bird uses illusion to wow a mate|last=Choi|first=Charles Q.|date=2010-09-09|website=msnbc.com|language=en|access-date=2020-04-22}}</ref>
