Re: 3D Imax question

[P3D Richard Young <young@xxxxxxx>]

P3D Sandman  <sandler@xxxxxxxxxxxxxx> asks about IMAX 3-D films. There were
some messages on this awhile back, on the new L5 3-D IMAX show. I just saw
it at the Kennedy Space Center at Cape Canaveral in Florida. It is truly
outstanding 3-D. The one I saw used passive stereo with two projectors
spaced apart from each other. Other IMAX 3-D systems use a single projector
passive system, and others use the flicker shutter glasses.

The resolution is only about 4,000 dots across the image, which is on 70 mm
film, but not at 1/3 the vertical height of typical movies --it uses a full
70mm x 70mm image. They supply a digital film recorder service, using a
custom film recorder, with a special camera built on top of a high-end
Management Graphics film recorder. Contact Gord Harris at IMAX Corp. about
film recording on IMAX.  He can be reached at 905-403-6340. He also has an
e-mail address that I can't find right now.

You can also look at Sony's description at:

and James Neihouse's "unofficial" IMAX page:

See it by all means.

Hint: fuse both the faces and the "stars".
Looks better with crossed rather than parallel viewing.
