Greetings:
Although I have not tested it, Rana Hossain's Flight Sim Manager 2.8 has what appears to be extreme camera capabilities, including various angles and altitudes. It is available on most flight sim sites or here:
http://www.ranainside.com/ This is a must have utility anyway. Too many features to list, but I use it mostly for adding aircraft, zipping unused aircraft and diagnosing problems. Plus, the author listens to suggestions and implements them.
good luck
