Intensity - how much light emitted from the light source.
Decay - how much light diminishes away from the source
light (fall -off)
Cone Angle - width of the lights cone of influence - area
outside cone not illuminated
Penumbra Angle - fall off at edge of cone angle - more
gives a softer edge to the light cone
Drop-off - how much the light diminishes at the outer
edges
Colour - set an RGB colour for the light - affects colour of
scene

Look to photographers for good
techniques
Think in terms of balance.
Avoid the overly dramatic.
Look at natural lighting.
Avoid saturated lights and hues
Normally only need a few lights.
Avoid disco colors and effects.

Shading is a
combination of the
basic material of an
object and any
textures that are
applied to it
In our presentation, we will discuss Materials.
Textures will be covered by the Modeling group.
