Re: Projection

[Michael Kaplan <mkaplan@xxxxxxxxxxxxxxxxxx>]

Alignment, by definition, requires comparison of two images. This can 
only be done *without* glasses, unless you're willing to blink 
sequentially L/R.

Focus can best be done *with* glasses, by closing one's left and right 
eyes sequentially and making necessary focus adjustments for each image.

Ghosting should *never* be a problem during projection. The polarizers 
should have been adjusted before the show begins.

For the record, I've solved all of the above by careful mounting, and 
projection using dual-Ektagraphics with autofocus. There is nothing to 
adjust during projection.

My problem, however, is that I usually lecture from a podium next to the 
screen, too far off axis to see the images in 3D.
