</h3>
<p id="999131" class="Body">
<a name="999131"> </a>The Depth Method pop-up menu lets you choose a control medium for applying depth.
</p>
<p id="999135" class="Body">
<a name="999135"> </a>Corel Painter uses the luminance (brightness) information in the control medium to determine how much depth is applied within a stroke. Light areas of the medium receive more depth; dark areas receive less. Black areas appear flat.
</p>
<p id="1006119" class="Body">
<a name="1006119"> </a>For example, when you use Paper as the Depth Method, the bright and dark areas of the paper grain determine where grooves and bumps appear in the stroke.

<p id="999150" class="ToDoBody">
<a name="999150"> </a>Erase applies only to depth, not to color. When you set the Drawing Method to Depth and Color, the Erase method removes depth while applying color.
</p>
<p id="999151" class="ToDoBody">
<a name="999151"> </a>The amount of depth removed depends on the value of the Depth slider. If you want to remove the entire Impasto stroke, set Depth to 0.

<a name="999164"> </a>Inverting a Depth Method
</h3>
<p id="999165" class="Body">
<a name="999165"> </a>You can invert the Depth Method using the Invert option. When a method is inverted, the negative of the source is used in the stroke.
</p>
<p id="999167" class="Body">
<a name="999167"> </a>For example, using Invert with Weave luminance switches the luminance values of the current weave so that light areas of the weave become dark and vice versa. This results in an inverted texture within the Impasto brush strokes.

<p id="999170" class="Body">
<a name="999170"> </a>When you start painting using a Depth Method, you're painting with a new medium - one that can have texture and builds up depth as you layer brush strokes.

<p id="999171" class="Body">
<a name="999171"> </a>The Impasto sliders in the Brush Creator let you set how much depth is applied with a stroke, the amount of texture applied within a stroke, and how each stroke interacts with other Impasto brush strokes.

<p id="999178" class="ToDoBody">
<a name="999178"> </a>When a stroke with a high Plow value encounters another Impasto stroke, it displaces the depth of the existing stroke. In essence your brush stroke "plows" through existing strokes.
