decreasing the Glow Threshold
value to 28%.
Now, the areas where we want to have glow are glowing, but it
is too concentrated. The Glow Radius value determines the radius
of the blur around the glowing areas. Increasing this value can
dissipate the glow a little, while still keeping the lava glowing. I'm
going to increase the Glow Radius value to 73 (Fig. 17.32).
This is looking better, but the glow is a little too intense. The
glowing areas are creating a haze over the entire image, which is
in effect brightening our shadows. This makes the glowing areas
