The lighting tutorials showed you ways in which to render your scene. The tutorials in this section cover additional aspects of rendering: Rendering an animation, how to use Depth-of-Field, and rendering large numbers of low-poly objects and proxies to reduce scene calculation time.
You can animate a Daylight system's time of day. This is a good way to create a shadow study.
This tutorial shows how to use the mental ray Depth-of-Field render effect to increase the realism of your renderings.
When you render a scene, the number of faces in the scene model directly affects rendering time: The greater the number of faces, the longer the rendering takes.
