Chapter 15 covers lighting 3D layers in After Effects. It discusses the different types of lights and their parameters, how lights interact with layers and their Material Options, the many secrets of shadows, creating gels and gobos, faking reflections, adjustment lights, projection lights, and using 3D lights to re-illuminate already-shot 2D footage.This was one of the best sources of information, on lights in After Effects, I've found on the web.

Chapter 14 covers creating and animating a camera, including creating camera rigs and taking advantage of auto orientation, as well as showing how to cut between multiple cameras. We conclude by discussing the camera’s parameters in more detail, including how to fake focus and depth of field effects.
