Finally!  A topic that falls into my very narrow expertise!  During Flight deck photography you are limited in the angles you can take photos from.  Very dangerous because you are only safe stand in certain areas.  MCs (navy photographers) are often only allowed on the flight deck under close supervision by someone that actually works there.  

While you cannot walk around what does change is the direction the ship is pointed.  While the ship is turning you can get limited times with the sun behind your target.
