If you have more than one camera, you can switch the camera through which you are viewing the scene.

To look through a camera
- Do one of the following:
Tip:
Camera views are found in the
Panels menu that is located along the top of the scene view. If the
Panels menu is not visible, press
Shift+M to show or hide the
Panels menu.

Like cameras, an object's position in the scene will be affected by dollying, tumbling, or zooming while looking through it.
Note: If your animation is disappearing into the background, adjust your
Focal Length setting. In any
Panel menu, choose
View >
Select Camera, then press
Ctrl +
A to open the
Attribute Editor and increase the value on the
Focal Length attribute.
