Thanks for the reply Rob. I have the background image set in the graphics window to help align the camera. I thought maybe someone had a methodolgy they use to set the camera to the view. I've gotten it close, but it's still not matching perfectly. Now what may be happening is that the PW camera is not able to reproduce the barrel distortions a real lens produces as the image nears the edges, though we have a good lens on a digital SLR.
