Constrain Geometry or Matte Paintings to Camera in Maya

From Stuart Christensen: Sometimes you need to control your background geometry and/or matte paintings to stay in sync with what your camera is doing, the concept is really simple and with a little practice you can create some dynamic scenes that obey the laws of optical perception. Stuart Christensen shows you how to use this method and some of the mishaps that might happen along the way, and how to animate the camera once a background or geometry has been attached. Play around with this for awhile and you will begin to see all the potential this method can offer. Enjoy!
