Um. If the time marker wasn't at 0 when you changed the camera's position, then you created a keyframe and animated the camera motion. When the timeline bar is visible, it is treated as 'always on', and any change is indexed. Expand the timeline bar (one of the two downward pointing arrows on the bottom left) and check and see if you have the main camera listed; if you do, then it has a keyframe. Deleting this should solve the problem (and also leave you back at the camera default position). Make sure the time count is set at 00:00, close the animation toolbar, relocate your camera again, and save. Then you can start getting your atmosphere worked out. Although you might want to create a test animation just to see the results. It -sounds- like what you have created is an animation where the camera will move and the atmosphere will mutate at the same time....
