Falloff Curve (under the Circular or Section Color group)
The Circular Falloff graph allows you to add weight to a particular color applied to your Lens Effect. By weighting the colors
that you apply you can choose to display more of one color than another. You can also make the transition of colors gradual
from one color to the next or you can create a sharp edge to the transition.
The Circular Falloff graph has controls at the top for creating and moving points on a curve on the graph below. The curve
represents the range of colors you have selected in the Circular Color group box to apply to the current Lens Effect. When
you open the graph you will notice that there is already a line with a point on each end which represents the linear transition
from one color to the next. By placing points along the curve, you can drag these points to increase or decrease a colors
intensity or to eliminate it altogether.
Buttons are available at the bottom of the graph that allow you to change the display of the graph. You can also manually
enter a horizontal or vertical position by entering a value into the two entry boxes.
