alternate vs. same-frame IMAX

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

Pardon me if this has been asked before.  I'm still trying to catch up, but
I seem to be maintaining a constant 2-week lag in reading digests.
We've seen some discussion here about the difference, in 3D movies,
specifically with shutter glasses, between offering each eye the same
instant of time and offering frames where the motion has progressed by the
amount of time between the two frames.  There was a message from Noel
Archambault, the cinematographer of "Across the Sea of Time", saying that
the two shutters were extremely well synchronized, and that it was shot with
each eye-view simultaneous.
My question, then, is why, in one of the views in the ViewMaster set (the
image of the boy looking at the fish in the fishtank), are the left and
right images so obviously taken at different times?  I had assumed, from
this difference, that the movie shutters were opened alternately, which
turns out not to be the case.  Was this just an accidental flaw in the
ViewMaster reel?  Is Sheldon Aronowitz, who produced the ViewMaster set, on
the photo-3d list?
