Fill effect, choosing a mask, and

fi lling it with a different color than

the solid layer it was applied to.

The edges of these fractal patterns are particularly ornate and

spectacular. However, this is one effect that is not designed

to be intuitive, except for mathematicians. The Set Choice

drop down, for instance, reveals such options as “Mandelbrot

Inverse over Julia,” which is almost as esoteric as the Equation

drop down options like “z = z^2 + c.” Occasionally, I might use

this effect to create luma mattes (you can't even use them for

alpha mattes because the fractals are created against a black

background, not transparency). Even then, the attractiveness of

this effect is greatly diluted by the fact that it renders incredibly

slowly (Fig. 9.30 ).
