As others have pointed out the main one is tilt and associated rise and fall, just occasionally I use front or rear swing (and associated shift). My own experience is that a camera with a fixed (rotatable) back and a front standard with tilt (either way), rise and fall, with ssing and shift is sufficient, that may also mean a drop focis bed.

“There’s no shot around here – time to head home.”
I’ve kept it simple, but I hope it builds up to our Zen-ish issue, will see you there... ;^)
