5 Light/Shadow range types

This is a discussion re: the 5 light/shadow range properties resulting from 2-3 point lighting [key light, fill light, and optionally rim or back light.]

Highlight
This is accentuated with our specular level, controlled in the material properties and possibly an additional light set to specular only in advanced properties. It shows the immediate bright light effect of the key light.

Halftone
This is the generalized, diffuse light from the key light.

Core Shadow
This is the shadow tone on the object itself from the key light.

Reflected Light
This is some light within the shadow from the fill light. It is also called “bounced light” at suggests radiosity, or light generated from the floor or other objects in the environment. The effect with a fill light is to “open up” the shadows, or make them less dense.

Cast Shadow
This is the shadow cast by the object from the spot light onto the surface plane ... note it is not completely black, has some transparency and soft edges. The fill light helps it from becoming too dark and dense.

Rim light
There is also a rim light or back light shown here, achieved by a light from behind the object to highlight an edge or perimeter against a dark backdrop
