I use a mixture of Direct and Indirect shifts (mainly rise and fall but sometimes lateral) depending on focal length, camera and surroundings.
With ultra-wides and indoors I generally just raise or lower the lens using direct shift. It is seldom a huge shift with a lens shorter than 90 and rigidity generally doesn't come into it.
With longer lenses I'll generally tilt the camera to frame the view I am after and then set the film plane to vertical with back tilt and then adjust the lens plane to where I want it to render the view I desire and the placement of the plane of sharpest focus.
I just wonder what others do.
