文档介绍：Lighting and Cameras
When you create a scene in Blender, you start with a few basic elements that will include
a camera, but may or may not include a light. Remember that what the camera sees is
what will render out as a picture or movie depending on what you tell the program you
want as a final output. To get a simple rendered view, press the “F12” key. This will open a
window that will display the rendered output of what the camera is focused on. If the picture
is black, you do not have a lamp or the lamp settings or placement in incorrect. To exit the
render window, press the “Esc” key.
Lighting
In most cases, you will need more than one lamp in order to properly illuminate your scene.
Most scenes usually require 3-4 lamps. Be careful not to use too many lamps! The different
types of lamps available for you to use are as follows:
Lamp- Basic Blender Lamp- shines all directions
Area- New lamp type- provides large area lighting (like a classroom)
Spot- Shines a direct angle of light
Sun- Provides an even angle of light, regardless of placement from objects.
Hemi- A wider light, much like area lights.
In traditional Blender rendering, only spotlights are able to cast shadows. However, with
the introduction of Raytracing (discussed in a later chapter) all lamps can cast shadows.
Lamp Settings:
To create a lamp, position the 3D cursor in a desired location and press the “Space Bar”
and select Lamp. The lamp will be placed on the screen. You now have several options to
select. With the lamp selected, click the Shader button and Lamp button to
bring up the adjusting options. Here’s what you see:
Distance and Energy Setting- how bright and
Lamp Types-choose the style how far the lamp shines
Lamp Color
Lamp Name Shadow and Spotlight Settings
There are other lamp setting available, but for now, these are the basics.

Spotlight Settings:
Spotlights are unique in that you can simulate a foggy scene with them and
