You can also increase the variation of depth that is applied by adjusting the Opacity
Jitter.
To choose an impasto drawing method
1 Choose Window Brush Control Panels Impasto.
2 From the Draw to list box, choose one of the following options:
• Color and Depth — applies brushstrokes with color and depth
• Color — applies brushstrokes with color only, depth is disabled
• Depth — applies grayscale brushstrokes to represent the highlights and shadows
created by depth, color is disabled
To control the appearance of depth
1 Choose Window Brush Control Panels Impasto.
2 From the Depth Method list box, choose one of the following:
• Uniform — applies brushstokes with even depth and little texture
• Erase — removes depth while applying color, which allows you to remove
unwanted Impasto brushstrokes. To erase depth, you must select the Color and
Depth option from the Draw To list box. The amount of depth removed
depends on the Depth value that is set. If you want to remove all depth, set the
Depth slider to 0.
• Paper — uses the selected paper grain to control the appearance of depth
• Original Luminance — uses the clone source luminance to control depth. For
more information, see “Using clone source or pattern luminance to create
texture” on page 620.
• Weaving Luminance — uses the selected weave pattern to control the
appearance of depth
3 Drag the Depth slider to the right to increase depth, or to the left to decrease it.
If you set a high value, you produce brushstrokes that have deeper grooves.
The impasto depth method option is not supported by all brush types.
You can create Impasto brush variants using only dab-based dab types, such as
Circular, Static Bristle, and Computed Circular.
When a brushstroke with a high Plow value encounters another Impasto
brushstroke, it displaces the depth of the existing brushstroke. In essence,
your brushstroke “plows” through existing brushstrokes.
