Bounce Lights
Bounce lights for characters are basically the same as bounce lights for sets,
described in Chapter 4, “Lighting Environments and Architecture.” Bounce
lights can be considered a type of fi ll light; the only difference is that they
simulate indirect light bounces instead of other sources of light.
To simulate light bouncing off the ground, you can aim bounce lights up
through the ground. Bounce lights usually look best with a quadratic or
inverse square decay, so the closer your character comes to the surface, the
more the lights illuminate nearby parts of your character.
In lighting characters, you need to be especially careful that all of your bounce
lights either cast shadows or are darkened by ambient occlusion, so that the
inside of the mouth, nose, or other interior surfaces don’t become too bright.
Also, bounce lights should not cast specular highlights. Nobody would
believe that a highlight on the lower part of a character’s eyeball was moti-
vated by soft indirect light bounced off the fl oor.
