[Focault's Pendulum]

The depictions I have seen sort of makes them look like a ring with blackness in the middle, some light escaping from the sides.

That's not light. You might be thinking of escaping Gamma Rays.

Let me ask you this. Isn’t it possible for objects behind the Black Hole to show up as a ring around the hole do to the bending of their light as it passes the parimeter?

I suspect the pull of the Black Hole focuses at some aspect of the hole. This may prevent what I’m referencing. If the gravity has it’s most pull around the mouth, it might be possible.

At any rate, I’m probably referencing artistic license from depictions I’ve seen over the years. It would be hard for Hollywood to show a black hole on film if there wasn’t some light to differentiate the blackness from other blackness.
