[photo-3d] Bothersome Dissolve or Projection in general???

["Dr. George A. Themelis" <drt-3d@xxxxxxx>]

Regarding the case of Brian's wife developing a splitting
headache during a stereo dissolve presentation, I have to
say that I have encountered cases of people developing
a headache in stereo presentation in general (not dissolve).

In particular, I remember during a presentation using a
TDC projector of perfectly aligned images (of course!)
someone got up and left.  Later he told me that he
developed a headache and could not stand it any more.
I have heard of a couple of isolated cases like this.

We discussed this a few years ago.  No one has a clear
understanding why this happens to certain people.  Perhaps
there are varying degrees of enjoyment and tolerance of 
stereo images presentation.

Brian, does your wife enjoy stereo projection in general,
or not?

After judging Detroit today for 4 straight hours (with a
total 4 hour of sleep the night before) I must say I had
almost reached the end of my rope... I said ALMOST!  It
will take a few more hours of misaligned stereo slides
to do it to me!!!
