I think he means what I mean (sometimes) in photo-3D.  If the purpose
of mounting a slide is for hand-viewer viewing, what constitutes "perfectly
mounted"?   Aren't the mounting requirements numerically different than for 
projection mounting?

To be more complete, the oldest-quoted question above probably should read

"And is any of this related to the reason why perfectly mounted-for-viewer"
slides  don't look right when projected?"

And when one means projection, use perfectly-mounted-for-projection.

The ambiguity arises I think because most people probably don't have
projectors, so the "default" for "perfectly mounted" may be for
viewers, rather than for projection where a technical-oriented person
would put the default (because it's the worse case condition).
