Remarks
Before doing something with a camera it is advisable to call IsUsable first. It's possible the camera has some properties which are undefined or is unable to perform certain requests. This happens when a camera is associated with an empty scene, the target/observer or other parameters has invalid values (not a number, for instance), or when the target and the observer share the same location etc.
