Using focus and esoterica effects 607

2 Choose Window  Color Panels  Color.

3 In the Color panel, do one of the following:

• If using an Image hose brush variant, set the additional color to black.

• If using another brush variant, set the main color.

If using the Image hose, the effect automatically controls mixing of the additional

color with nozzle elements to produce depth shading. Shadows tend toward black,

so black is a good color to use.

4 Choose the Rectangular Selection tool from the toolbox.

5 Drag to create a selection.

This selection determines the location and size of the effect.

6 Choose Effects  Esoterica  Place Elements.

7 Adjust any of the following sliders:

• Iterations — controls the spacing of iterations. In each iteration, the points

distance themselves from each other on the surface of the virtual sphere. The

points start at random locations, so if you set zero as the number of iterations, the

placement of the points is completely random. Higher numbers of iterations

increase the regularity of the spacing.

• Points — sets the number of points to create on the virtual sphere. Each point

correlates to an image element placed.

• Radius Fraction — determines the size of the virtual spheres created at the

second and third levels. The first-level radius is multiplied by the fraction

amount to determine the radius of the second-level spheres.

The fraction is used again between the second and third levels. Higher values

(above 1.0) increase overlapping of the spheres. Lower values (below 1.0) preclude

overlapping (when sufficient iterations are used to distribute the points).

• Oversizing — controls the diameter of the first-level virtual sphere in relation to

the selection marquee. At a setting of 2.5, the sphere fits within the selection.

Higher settings shrink the sphere. Lower settings stretch it beyond the selection.

• Ambient Amount — controls the use of the additional color in elements that

appear on the virtual sphere away from the light source. This is how the clump of

placed elements exhibits coherent three-dimensional shading when black is used

as the additional color. The default setting is 0.7, which produces good shading

results. Increasing the value brings in more of the additional color. Decreasing it

reduces additional color mixing.

8 In the Levels area, enable one of the following options:

• 1 — specifies that each point receives only one element
