Thanks Terrill but that's just too simple of a solution, I was hoping for something a little more complicated
I love when I do this kind of stuff, making a mountain out of a mole hill and completely missing the obvious, easy answer! Thanks again, I'll give it a try. I may also try cutting the center rod of the tripod and installing a locking swivel coupling.
I originally showed how I couldn't get the perspective correct when I tried matching the angle of the background to the camera but I accidentally lost the photo. Here it is again, came out a little warped.
