[1/5/1/1/4/1/1] The camera direction is for the inverse direction of the black hole (1 of 2).

The camera and relating objects are aligned as a black hole, a rocket with the camera, another resting rocket (as an object) near a black hole, and a spiral galaxy on a line. In terms of the radius value r where the event horizon is assumed to be at r = 1, the black hole is at r = 0, the camera is initially at r = 4, the restring rocket is at r = 5, and the galaxy is at r = 50 (I think r = 50 is too close to the black hole). The camera, watching the resting rocket and the galaxy, falls into the black hole.

The light ray from the resting rocket and the galaxy are blue-shifted due to the gravity. Furthermore the rays are strongly bent by the gravity so that the view area of the camera (the area where the light rays emitted from the rocket, galaxy, and the stars come) becomes more narrow when the camera goes closer to the black hole. Finally the camera see a thin bright blue circle in from of it. The outer region of this blue circle (the gray area) is the event horizon of the black hole.

The following movie continues until the numerical computations of the CG program breaks down.
