Parameters in the Inspector
•
Aspect Ratio: Sets the aspect ratio of the mask. Values include 1.66:1, 1.70:1, 1.78:1, 1.85:1, 2.35:1,
2.55:1, and 3.00:1.
•
Oset: Sets the position of the mask relative to the Y center of the object. Values range from
–1.0 (the bottom of the object) to 0 (the center of the object) to 1.0 (the top of the object).
•
Border Size: Sets the thickness of the border.
Note: The border has no eect on the aspect ratio mask. It adds a frame at the edge of the
image created by the mask.
•

triangle to include Red, Green, Blue, and Opacity sliders to more precisely select the color of

Color Correction lters
Color Correction lters overview
The lters in the Color Correction category can be used in a number of ways. For example, you
can set a mood by making an image sepia-colored. In addition, these lters can x a problem
with contrast, color, gamma, or brightness.
For a description of each Color Correction lter, see the lters list in the Help table of contents
(the sidebar to the left of this window).
Brightness
Boosts or lowers the uniform brightness of an image by a specied amount.
Although this may seem to be the rst lter to use to correct for improper exposure in an
image, Brightness boosts or lowers everything in an image at once. This means that raising the
brightness in an image raises brightness everywhere, including in the shadows. Consequently, a
brightened image can look washed out.
However, this lter is useful for modifying the edges and eects of shapes, masks, particle
systems, and generators.
A better lter for exposure correction is the Gamma lter. For more information, see Gamma on
page 776.
