Actually not quite correct. The camera and spaceship will generally have different starting positions of their center of gravity but the same starting velocity, leading them to drift apart.

The only real relevant thing for the photograph is rotation though as long as the camera doesn’t float in front of the window frame, and airflow is probably much more relevant for both points than gravity.

That are the tidal forces, they are quite small for a system of the size of Orion.

Right, I was talking technically. That’s what I tried to say in the second paragraph.
