The visual effect of a "Dutch tilt" is similar whether the image is flat or
stereoscopic.  Like many "effects" the usage is somewhat limited to specific
applications.  It is probably the simplest of all effects, since all that is
done is to tilt the camera, rather than holding it perfectly level.

I mentioned some of the applications - leaning while going around a corner
in a vehicle, on a bicycle, skates, etc.   It is sometimes used for an
"artistic" impression.

You may have seen this in certain TV commercials or music videos.

There are valid applications, but usually they are limited.  Like all such
unusual camera angles, they are most effective if done sparingly, and with a
logical reason.

Some people have said to never tilt a stereo camera.  Not true.  A stereo
camera may be tilted in any situation where you would tilt a mono camera.
You can tilt a stereo camera (or dual camera rig) up or down or diagonally
(the "Dutch tilt") as well as pan it to the left or right.

It is easiest to do with a single-body stereo camera.  If done with a two
camera rig, the two must be locked together, as to a common base or rail.

This is because the baseline must remain constant (a source of confusion
regarding the so-called "never tilt" rule).  As long as the baseline remains
the same for both cameras, the rig as a unit may be tilted the same as if it
were a single stereo camera.
