It has deeper contrast, but with slightly softer values leading from the
diffuse color.
Contrast Changes the contrast level between the diffuse and ambient areas of the surface
when lit.
Soften Diffuse Edge Controls the softness of the edge between the diffuse and ambient
areas of the lit surface.
Light Components
Light in a CG program is differentiated into an ambient, a diffuse, and a specular component.
The ambient component of light is the general ambient light in a scene. There is no
Both decay and attenuation are important to use when the light needs to be realistic. Light
decays in real life; your renders will assume a higher fidelity when the lights in them decay.
The effect may be subtle, but it can make a large difference.

direction to ambient light, and the light itself is cast evenly across the extent of the scene.
The diffuse component of light is the way it illuminates an object by spreading across its
surface. The specular component of light is how the light creates highlights on a surface,
especially when that surface is glossy.
