The 53 inch width is really only suitable for fairly close pictures of one person. The geometry angles are such that if the subject width is 24 inches, and the background is twice as far as the subject, then it requires 48 inches of background width (and careful alignment). :smile:
You could put the subject closer to the background to minimize this width, but then you may cause subject shadows on the background.
You can "test" this width by setting up some subject in front of any wall, to see the wall width that is visible to the camera.
