That's great as long as your subject is on one plane. If you extend DOF in
one direction (horizontal plane) with camera movements, you lose equal DOF
on the opposite (vertical) plane. You still need a small f/stop to cover it
all.
Landscapes of flat fields, roads, stuff like that is great for getting DOF
from your feet to infinity using camera movements. Put a few trees or a
fence reasonably close to the camera, in the scene, and you cannot use
camera movements to cover the needed DOF. This is why LF lenses frequently
go to f/128.
You can use a multitude of camera movements to gain a wee bit of DOF
advantage when you have multiple planes in the scene. But small f/stops are
still going to carry the ball in these cases.
I frequently photograph large flat seascapes with DOF from my feet to
infinity at f/8 or f/11 on my 4x5. But there is no vertical component. Just
a rock sticking up a few feet anywhere near the camera and most is lost.
You can reach a happy medium and then start stopping down until it all
comes in focus. This puts you back at f/32 or f/45.
