pick out areas of shadow and highlight to create visual interest.
Painting Glows with Linear Dodge
The glow effect is created on the sphere using a Linear Dodge (Add) layer blending mode. The same Linear
Dodge (Add) layer is used to create the impression of translucency in the skin. A common Subsurface Sc-
attering effect is to see the scattering of light in the material along its edge. This is most commonly seen in
backlit ears. Subsurface scattering also manifests as a radiance or glow to the skin. We will create a similar
translucency effect to the shell of this character's head. Follow these steps to create the glowing sphere and
backlight effects.
1. Create a new layer and name it “Sphere Color.”
2. Select a soft round brush and from the color picker select a purple hue ( Figure 5-56 ).
3. Set the layer blending mode to Linear Dodge (Add) and start to paint the purple over the sphere. It will
take on a luminescent quality as a result of the layer blending mode. Adjust the layer opacity as needed to
get the proper intensity for the effect ( Figure 5-57 ) .
