How do I adjust a perspective camera's horizon so that it appears lower?

Traditionally and by definition, the horizon is a circle that forms around a camera’s head, so that if viewed in-game, the horizon is perfectly at the center of the screen.

What I would like to do is change the camera so that the horizon is lowered. Say for example we have the following view:

The horizon can be seen at the middle of the screen, where the plane seems to end.

I want to modify the camera so that it renders like this, with a lower horizon but with the same angle.

How can this be achieved?

I’m looking for the same thing! did you figure out some way? thanks!!
