You can save and reuse any changes you have made to a camera in the Camera settings with the Save as Default option. 
- Once you have established a camera setup that you like, click Save as Default in the Camera settings Picture Format area. 
Every camera you add to your scene now will use these default settings. 
  
- Experiment with the camera view. 
 
- If you want to recall your camera’s custom default, click Reset. 
This lets you experiment with your default camera views without losing the settings you originally defined. 
 Note: The Reset button does not restore MotionBuilder (or “factory”) default camera settings.
