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.
•
Offset: 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 effect 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
the border.

Color Correction filters
Color Correction filters overview
The filters 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 filters can fix a problem
with contrast, color, gamma, or brightness.
For a description of each Color Correction filter, see the filters 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 specified amount.
Although this may seem to be the first filter 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 filter is useful for modifying the edges and effects of shapes, masks, particle
systems, and generators.
A better filter for exposure correction is the Gamma filter. For more information, see Gamma on
page 776.
