Please note that when shifting the back plate of the camera body up more of the lower
part and when down more of the upper part of the image will be visible.
As the digital back and not the lens is shifted the two files can be merged easily and

The precondition for shift is that the image circle of the lens is sufficient and that
optional lens shades are removed. In general: the longer the focal length, the bigger
the image circle. Here are some examples of image circles and maximum shift:
