Nikon on a stick

I have a monopod that I use with a small ball head and a Nikon D3000 with a fisheye lens. Sometimes with a Canon 5D and a 17-40 f/4 0r a fisheye. This gives me the ability to shoot from above while standing on the ground. It's obviously hit and miss as to framing, but you can get pretty good at it after a while. Keeping the horizon straight can be tricky, so I custom rotate in Photoshop, which loses a bit of the image. First image is with the Canon at 17mm, no rotation needed. Second is with the Nikon and fisheye. This was a 4 degree rotation to get the horizon level.
