tiltshift is trick you can do with view cameras (i.e. the old skool ones with the lens and plate attatched by bellows)
tilt and shift are two different things (but often used together) one is to keep parralel lines parralel (tall buildings, raillways etc) thus removing the sense of prerspective. The second is to alter the focal plane so that is passes through a smaller part of the subject or brings the whole thing into focus.Posted 8 years agoGrahamSSubscriber
Doesn’t have to be old school view cameras. Nikon have been making tilt-shift lenses for 35mm SLRs since 1967.

so how is shooting portrait going to help straighten railway lines so they are parallel. if i was to wander down to the level crossing and point my camera down the railway line and shift the full 11mm of vertical shift it’s going to do very little.Posted 8 years ago
if you could get nearly overhead of the railway lines all shifting would do is move your crop if you and your camera are parallel to the lines everything is square. if your camera is pointing to the side so that the rails look further apart on one side of the image you need to swing the film plane to ‘distort’ the image back to square and tilt the lens to regain focus (because moving the film plane has changed the angle of focus).
you can’t do this with a 35mm camera and T/S lenses you need a view camera with movements at the film plane as well as at the lens.
