Lighting in 3D animation is an art all its own.

Chapter 4 Lighting 145
Did you know that light intensities can range from values in the negative range to values in
the thousands? You can set a light intensity to 9000% (or higher) if you want, just by typing
in the value. The results might not be that desirable and perhaps even unstable, but you
never know what your scene might call for. In general, if you want to create a bright sunny
day, you can use a point light, which emits light in all directions, with a light intensity of
150% or so for bright light everywhere. On the other hand, if you want to light an evening
scene, perhaps on a city street, you can use spotlights with light intensities set to around
60%.As you build scenes throughout this book, you??™ll be asked to set up different light types,
with varying intensities. This will also help you get a feel for setting the right intensity.
Note
Negative lights, or ???dark lights,??? can also be handy depending on the scene you??™re working
on.Whereas lights with a positive light intensity can brighten a scene, negative lights
can darken a scene.
