this image so straight that it looks like it just graduated from a
military academy. Either that or it saw a chiropractor (Fig. 7.55).
All joking aside, the real purpose of this effect is to aid in com-
positing. If we did have to composite a character, or some other
object, into this scene, we would have a diffi cult time making
a believable composite because of the lens distortion. That is
the reason that this effect can add lens distortion or remove it.
Of course, the example I have here is exaggerated so that you can
see the results. But even a subtle inconsistency in fi eld of view
can cause a composite to look artifi cial.
