I was using a view camera before you were born. My old 8x10 wide angle camera has a 4 inch rise or fall the lens board moves up or down bellows do not this rise or fall on this camera is croping a large very large circle. The camers were called skyscraper cameras. Lens movments are used for many things one is croping. James Romeo

Have you ever used a view camera? Your comments lead one to believe that
you have not. The closer to the lens the subjects are the more pronounced
the effects of a shift (rise and fall in this case) will be. In view camera
work moving the lens a matter if a few mm make BIG differences. Its not a
cropping tool but part of the creative process to make the image look as you
see it in your mind's eye. Raising the camera and lowering the front
standard yields much more foreground, simply lowering the camera will not
do that much.

This is what a shift does

if moving your head up or down a foot or so doesn;t significantly change the
angle of view how can an inch or two do it with a lens, an inferior
subsstitute for the eye? no, what it does is place on the negative the
desired part of the larger image available with a lens covering
significantly more than the format. a shift is a cropping device, no more.no
less. if you had the whole image circle formed by the lens a shift of a foot
wouldn' amount to an anthill.
