706 Chapter 10 Using Filters
Adjusting Filters
Filters can be tailored to your specific needs by adjusting their parameters. The
parameters can be adjusted in a number of different ways, such as using sliders in the
Dashboards, the controls in the Inspector, the onscreen controls, by adding keyframes,
or by applying parameter behaviors.
Using the Dashboard
Each filter has a subset of parameters that appear in its Dashboard. All of the controls
available for modifying each filter also appear in the Filters tab of the Inspector. Both
the Dashboard and the Filters tab reference the same parameters—changing a
parameter in one automatically changes that parameter in the other. Frequently, the
controls available in a filter’s Dashboard represent the parameters with the exception of
the position parameters. For example, compare the controls for the Fisheye filter in the
Filters tab to those available in the Dashboard:
Most filter parameters have only a single set of numbers that represent their value.
Parameters with a disclosure triangle, however, may have additional numbers that
represent a different way of describing the same value. In the case of the Center
parameter, the numbers indicated in the value sliders are absolute values, but the X
and Y values under the disclosure triangle represent percentages. If the defaults for X
and Y are both 0.5, that represents the center of the image. Changing the percentages
updates the absolute values in the value sliders.
Adjusting Parameters
Each filter has its own distinct set of parameters. These parameters can be adjusted in
one of two places: the Filters tab of the Inspector, or the filter’s Dashboard. As with all
parameters in Motion, the Dashboard contains the most essential parameter controls
for modifying a filter, whereas the Filters tab in the Inspector contains the filter’s entire
list of editable parameters.
Note: Often, the parameters in the Dashboard are equivalent to those in the Inspector.
For more information on accessing the Inspector and Dashboard controls, see “ The
Inspector ” on page 98 and “ The Dashboard ” on page 105.
