Not sure what you mean by extreme, but here is one where I used all normal movements in one image, though none were particularly extreme, just enough to obtain the desired effect:
Movements are:
1) Front fall (= rear rise) to make my camera position seem lower than it really was.
2) Front shift left (= rear shift right) to make it appear as though I'm standing in the water -- I'm not, I'm standing up on the bank to the right.
3) Front forward tilt (not the same as rear back tilt) to alter PoF from immediate foreground upstream to trees at the creek's edge at the center rear of the image.
4) Rear swing counter-clockwise (not the same as front swing CW) to alter PoF from trunk of tree at lower right corner across the line of rocks in the stream to the evergreen's trunk on the other side of the creek.
Note that rear movements alter the geometry of 3-dimensional shapes and can exaggerate perspctive and spatial relationships. In this case I used rear swing instead of front swing to make the trunk and rocks at lower right appear larger. By contrast, I did not use rear tilt because I did not want to impart any lean which would be noticeable in the trunks of the trees. This image was shot with a 90mm lens (Nikkor f4.5), 2 seconds at f22 on Fuji Velvia 50 (rated at 40). I obtained that reading with my spot meter by placing the yellow leaves on the background Aspen in Zone VI. I did not record the actual amounts of the movements, but they were probably about 20mm of fall, 20mm of shift (combo well within the lens' usable Image Circle), 4 or 5 degrees forward tilt, 2 to 3 degrees swing.
Cheers,
