Thanks, Piers.
I had worked out that it was shift alone; I suppose tilt is self-explanatory.
But what I find hard to appreciate is that such small movements in the lens can
give you such a change in apparent level of camera; it's much more effective
than merely raising the camera with your arms, for instance.
The other snag is that, with this system, you need really to have the camera on
a tripod.
