</h3>
<p id="1014615" class="Body">
<a name="1014615"> </a>Marbling creates intricate distortions of an image, following a technique that dates back to the 12th century.
</p>
<p id="1014619" class="Body">
<a name="1014619"> </a>The marbling effect is created by dragging a fork, or rake, across an image, creating an effect similar to a fork dragging through a mix of chocolate syrup and melted ice cream.
<a name="1000853"> </a>Each time you drag a rake across an image, you create a <span style="color: #000000; font-style: normal; font-weight: bold; text-decoration: none; text-transform: none; vertical-align: baseline">step</span>. You can create marbling recipes that include several steps-each one using a different rake, direction, and waviness. You can save marbling recipes and reuse them.
</p>
<p id="1000854" class="Body">
<a name="1000854"> </a>Marbling works best with patterns or textures. The Blobs effect is an excellent way of creating the raw materials for marbling; filling with a pattern is another. Refer to <a href="15-Effects12.html#1000986">"Blobs"</a> for more on the Blobs effect.

</p>
<p id="1000863" class="ToDoBody">
<a name="1000863"> </a>Selections can help you control the marbling when you have a particular effect in mind. For example, the rake path normally begins from the edge of the image. If you want the rake path to begin in the center of a blob, select an area that begins at the blob's center.
<li class="SmartList1" value="4"><a name="1000876"> </a>Create a rake stroke by adjusting any of the following sliders and clicking Add Step: </li>
</ol>
<ul>
<li class="Bulleted2"><a name="1000879"> </a>Spacing adjusts the distance between rake teeth. The slider controls the number of teeth in the rake. When the slider is all the way to the right, the rake has one tooth.</li>
<li class="Bulleted2"><a name="1000881"> </a>Offset moves the rake perpendicular to the path direction. Use Offset to adjust the position of the rake lines.</li>
<li class="Bulleted2"><a name="1000883"> </a>Waviness changes the amplitude (height) of the waves. When Waviness is set to zero, the path is straight.</li>

<li class="Bulleted2"><a name="1000887"> </a>Phase slides the wave in the rake direction. This lets you set where in the curve-peak, downslope, valley, or upslope-the rake begins in the image.</li>
<li class="Bulleted2"><a name="1000889"> </a>Pull controls how much the rake distorts the image. Lower values produce thin, short distortions. Higher values create stronger distortions.</li>
<li class="Bulleted2"><a name="1000891"> </a>Quality lets you control the smoothness in the marbled image. Low Quality settings produce an aliased effect.

</h3>
<p id="1046346" class="Body">
<a name="1046346"> </a>The Auto Clone effect automatically applies brush dabs to your image. The types of dabs depend on the currently selected brush. The color is picked up from the clone source.
</p>
<p id="1000920" class="Body">
<a name="1000920"> </a>The best way to produce a Natural-Media version of an image is to first clone it and then choose a brush that produces artistic dabs. The Driving Rain variant of the Cloner brush works well for generating a hand-drawn look. The Seurat variant of the Artists brush also works well.
<a name="1005935"> </a><i>In this example, the Seurat variant was used with the Auto Clone effect.
</i></p>
<p id="1000929" class="Body">
<a name="1000929"> </a>The Auto Clone effect has no dialog. It uses the current brush settings and the clone color.

</p>
<p id="1000934" class="Body">
<a name="1000934"> </a>If you apply Auto Clone to a large area, the paint may fill smaller rectangular tiles one at a time. If you click to stop the Auto Clone, it won't automatically finish the final tile of the overall selected area. To fill in non-rectangular areas, you can use Auto Clone with a selection. For more information, refer to <a href="12-Selections4.html#999057">"Creating Selections"</a>.
</p>
<p id="1000942" class="Body">
<a name="1000942"> </a>When you use Auto Clone with the Felt Pen Cloner and other tools that turn black as you repeat strokes, areas darken rapidly. You can slow down the color buildup and still use Auto Clone by dimming your original image.
</p>
<p id="1000944" class="Body">
<a name="1000944"> </a>Another way to automate cloning is by recording and playing back individual brush strokes. This feature is especially useful for filling in backgrounds. For more information, refer to <a href="06-Painting13.html#1013418">"Recording and Playing Back Strokes"</a>.

<a name="1001298"> </a>The effect automatically controls mixing of the secondary color with Nozzle elements to produce depth shading. Shadows tend toward black, so this is a good color to use.
<li class="SmartList1" value="6"><a name="1001300"> </a>In the Place Elements dialog box, specify a number of iterations.</li>
<p id="1001311" class="ToDoBody">
<a name="1001311"> </a>In each iteration, the points seek to 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, their placement is completely random. Higher numbers of iterations increase the regularity of the spacing.

<p id="1001316" class="ToDoBody">
<a name="1001316"> </a>With two levels, each point receives an element, then is used as the center for another virtual sphere on which point iteration and element placement repeats.

<p id="1001318" class="ToDoBody">
<a name="1001318"> </a>The number of elements increases rapidly with more than one level. For example, if you choose 12 points and three levels you'll create 12+(12x12)+(12x12x12) = 1884 elements. Of course, many of these will probably be covered by later placements.

</p>
<p id="1001322" class="ToDoBody">
<a name="1001322"> </a>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.)

<li class="SmartList1" value="11"><a name="1001327"> </a>Adjust the Ambient Amount slider.</li>
<p id="1001329" class="ToDoBody">
<a name="1001329"> </a>Ambient Amount controls the use of the secondary 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 secondary color. The default is 0.7, which produces good shading results. Increasing the value brings in more of the secondary color. Decreasing it reduces secondary color mixing.
