Corel Painter 137
You can adjust the appearance of depth in the
entire Impasto layer with the Amount slider.
• Picture controls how much color
appears in the image. At its lowest
value, all the color is washed out,
leaving only the highlights.
• Shine controls how much
highlight appears on the surface of
strokes. Higher Shine values make
the stroke look metallic.
• Reflection maps a clone source
image or pattern onto the texture
at a variable percentage. Refer to
“Working with Reflection Maps”
on page 284 for more information.
Adjusting Surface
Lighting
Lighting can be a big part of the
overall depth effect Impasto creates.
Just as the right lighting can bring out
the deep textured look of a stroke, the
wrong lighting can wash out the effect
altogether.
The Surface Lighting controls let you
set up the position and attributes of
light sources that shine on your
Impasto brush strokes.
These controls are global, meaning
they affect all the Impasto brush
strokes on all layers.
Setting Light Position
The lighting sphere shows all the
possible surface angles and how the
lights illuminate them. The light
indicators on the sphere show the
current positions of all the light
sources.

Adding and Deleting Lights
You can add as many light sources as
your system’s memory allows.
Remember, each light interacts with
all the Impasto brush strokes, so be
careful not to set up colored lights that
clash with the colors in your
composition or light sources that
created unwanted shadows.
To add a light:
• Click on the lighting sphere.
