3 Use Orbit on page 7611 to move the camera until the perspective of
the scene roughly matches that of the still image.
4 Adjust the camera's perspective on page 7607 to fine-tune the
perspective match.
5 Use Move on page 959 with the camera or target to position the
scene against the background.
If you raise or lower the camera, raise or lower the target by an equal
amount, in order to keep them level and maintain the horizon.
You can also use the Camera Match utility on page 5249 to match the
perspective of a camera to a photograph. You will need accurate scene
measurements to do so.
Animating Cameras
You animate a camera by using transforms or changing its creation parameters
in different keyframes while the Set Key or Auto Key button is on. The program
interpolates camera transforms and parameter values between keyframes, as
it does for object geometry.
See Auto Key Animation Mode on page 7549 and Track View on page 3503 for
further descriptions of animation. This topic summarizes some possibilities
and suggests some techniques.
In general, it’s best to use a free camera on page 5203 when the camera is to
move within the scene; use a target camera on page 5205 when camera position
is fixed.
Moving a Camera Along a Path
Having a camera follow a path is a common way to create architectural
walkthroughs, roller coaster rides, and so on.
■ If the camera must bank or tilt close to the vertical (as on a roller coaster),
use a free camera. Assign the
Path constraint on page 3297 directly to the
camera object. The camera follows the path, and you can adjust its point
