Look at your Noblex slides.  With the camera properly leveled the horizon
should be strictly at the center of the images if the lens is not shifted.
If you shift your lens, the horizon drops down so you get more sky and less
ground.  If you want more ground and less sky,  you would have to shift down.
Using a Noblex down-shift would mean inverse mounting.

For swing lens cameras,  the camera must be level to have a straight horizon
across the image center.  This has nothing to do with your tripode height.
stretch or lower your tripode affects the foreground only.  The horizon is 
always in the center.  Tripode height is negligible compared to the distance
to the horizon which is infinity.

If you however can tolerate distortions,  particularly not so strictly
straight horizons, you can just tilt the camera up and down. I've done this 
many times. With slight tilt pulling something into the frame, distortions were
hardly visible. With moderate tilts to include a couple of mm of more ground 
or sky, the horizon fell off the straight line only near the two endd of the
frames. If you are in a forest, you can just do whatever you like.  Who knows
if this is a hill or slope?  You may not have to invert your Noblex anyway.
