distance from ground vs horizon line

[cheerioboy]

Is there ever a situation/angle when the vray plane or the camera horizon line not physically correct? I'm asking because in some aerial images that I've been working on I've started to chop a bit of the horizon down because it looked like it went too far. It would be great to have a vray plane that took into account the curvature of the planet so that horizon lines from off a beach or so forth were more physically correct.

or maybe I'm just way off base, anybody have any input into this?

cheers

If the camera is high enough?
