Camera Attributes
As an example, set your project to Lighting, and load the still_life_render_v02.mb scene
from the Lighting project on the CD. You'll see a green box in the persp panel that dis-
plays the resolution (set to 640 × 480) and the name of the camera (camera1).
Special attributes control the function of camera
nodes. To set these attributes, follow these steps:
1. With camera1 selected, open the Attribute
Editor (press Ctrl+A or choose View Camera
Attribute Editor).
2. At the top of the window, select the type of
camera controls you want. The Controls attri-
bute sets the type of camera from single- to
two- to three-control nodes. Figure 11.17
shows the Attribute Editor for the camera.

Focal length
The Focal Length attribute specifies the length of
the lens. The lower the focal length (a.k.a. short
lens), the wider the view. At very low numbers,
however, the image is distorted, as you can see in
the comparison in Figure 11.18. The higher the
focal length, the closer the subject seems to the
camera.
