• Amount controls the degree of
displacement. Increasing the
Amount distorts your image
more.
• Variance creates multiple varia-
tions in the neighborhood of
the displacement. The result of
increasing variance depends on
the type of image and other set-
tings.
• Direction controls the direction
of displacement. Three o’clock
corresponds to 0°. The Refrac-
tion map type is not dependent
on direction.

ing faster.
• Angle sets the direction in
which the image appears to
travel. Zero degrees blurs in the

• Thinness blurs the image in a
direction perpendicular to the
angle you choose with the
Angle slider.

green, and blue components of color;

based on luminance.
