I am confused by the terms "horizontal" and "off-axial" adjustment.

It seems like they should be "horizontal" and "vertical".

And these depend on camera orientation. The distance between camera base and lens axis is "horizontal" only if the camera is in portrait orientation. In landscape, that same distance is "vertical".

Pictures should make this clear.

Perhaps it would be even more clear to refer to these offsets as "basal" and "lateral", or some such.

Is there a standard nomenclature for these things? Where is it defined?
