That is does as you've demonstrated here, Earl. I'm still finding it a bit hard to get a perfectly level horizon with my fisheye though. I love these shots!

Just a small demonstration to show how the apparent curvature of the horizon is simply controlled by tilting the camera. Tilt the camera downwards & the horizon line curves upwards (convex). Tilt it up & the horizon line curves downwards (concave). Hold the camera level for a straight horizon. Please feel free to download.
