Original image (left), with Edge Type set to Roughen (center), and with Rusty Color (right)
Edge Type What kind of roughening to use.
Edge Color The color to apply to the edge for Rusty Color or Roughen Color, or to the fill for Photocopy Color.
Border How far, in pixels, the effect extends inward from the edge of the alpha channel.
Edge Sharpness Low values create softer edges. High values create sharper edges.
Fractal Influence The amount of roughening.
Scale The scale of the fractal used to calculate the roughness.
Stretch Width or Height The width or height of the fractal used to calculate the roughness.
Offset (Turbulence) Determines the portion of the fractal shape used to create the distortion.
Complexity Determines the level of detail in the roughness.
Note: Increasing complexity results in longer rendering times. Reduce the Scale value rather than increasing Complexity
to achieve similar results.
Evolution Animating this setting results in changes of the roughness over time.
Note: Although the Evolution value is set in units called revolutions, it’s important to realize that these revolutions are
progressive. The evolution state continues to progress infinitely at each new value. Use the Cycle Evolution option to
return the Evolution setting to its original state at each revolution.
Evolution Options Provide controls that render the effect for one short cycle and then loop it for the duration of your
clip. Use these controls to prerender the roughen elements into loops, and thus speed up rendering time.
• Cycle Evolution Creates a loop that forces the evolution state to return to its starting point.
• Cycle (In Revolutions) The number of revolutions of the Evolution setting that the fractal cycles through before it
repeats. The timing of the Evolution cycles is determined by the amount of time between Evolution keyframes.
Note: The Cycle control affects only the state of the fractal, not geometrics or other controls, so you can get different results
with different Size or Offset settings.
• Random Seed Specifies a value from which to generate the fractal noise. Animating this property results in flashing
from one set of fractal shapes to another within the same fractal type. For smooth transition of the fractal noise, use
the Evolution control.
Note: Create new roughness animations by reusing previously created Evolution cycles and changing only the Random
Seed value. Using a new Random Seed value alters the noise pattern without disturbing the evolution animation.
Solarize effect
The Solarize effect creates a blend between a negative and positive image, causing the image to appear to have a halo.
This effect is analogous to briefly exposing a print to light during developing.
