Add > Add Effect dialog > Lens Effects > Choose any effect, and click the (>)
arrow button. > Options tab of the rollout for that effect > Radial Density
(under the Additional Effects group)
The Radial Density dialog allows you to add weight to any additional effect
applied to the Lens Effect. By weighting the density of the additional effect
that you apply you can choose particular areas in the effect to display more
of the additional effect or to eliminate it altogether. You can also use Radial
Density to gradually fade the additional effect from maximum density down
to zero or you can create a sharp edge to the transition.
