Across the Sea of Time VM set

[P3D Morris M. Keesan <keesan@xxxxxxxxxxxxx>]

I just realized an interesting fact about _Across_the_Sea_of_Time_, the movie
running at the Sony IMAX theater in New York.  I was looking at the set of
View-Master reels that we bought at the gift shop, and thinking that some of
them looked "wrong", somehow.  One shot in particular looks funny, image 5
on reel B, "Tomas Minton Enjoying the Sights in Chinatown", with Tomas looking
at the fish in a fishtank.  Something's wrong with Tomas's eyes, and with the
fish, and looking with alternate eyes shows that this picture was not taken
with a still camera, but with a movie camera that exposes the left and right
images alternately, which allows the same frame rate as a non-stereo movie,
even though each eye only sees half as many frames per second.  If you have
this View-Master set, look at Reel B, Image 5, and notice that in the 1/24
second between the left and right views, Tomas has shifted his gaze slightly,
and the fish have moved a bit relative to each other.

This is a great demonstration, for those of us doing still photography, of how
important it is to get your left and right exposures synchronized, even in
shots which don't seem to be "action" shots.
