Lighting is perhaps the most important aspect of
CG, as this stage of CG production really makes or breaks a scene.
Once your lighting is ready, you render the scene. This is akin to developing your photos.
Knowing what the end result should be will dictate how you decide to render. You can choose
several settings for quality and output, for example, so you can show off your scene to your
friends (although a QuickTime movie can??™t be hung on the fridge the way a photo can).

Of course, with CG you also have control over time, because you can animate your
scene. The workflow we??™ll discuss in this chapter is best illustrated with a film production
example. The next section will briefly describe a film production workflow and how it
relates to CG production.
Production Workflow
There are three major stages to producing films: preproduction, production, and postproduction.
In preproduction, the script is written, storyboards are drawn up to outline the
action, costumes and sets are designed and built, the actors are cast and prepared, and a
production crew is put together. During the production phase, the scenes are set up and
shot according to a production schedule that lays everything out in the most efficient
manner possible.
