Beam Splitter Stereo Processing

[P3D Ralph Johnston <copley@xxxxxxxxxxxxxxxxx>]

In reference to the recent letter stating the IMAX theaters probably used
polorized glasses:

They use LCD (liquid crystal) type shutters in a headset with a radio
receiver built in.  This completly blanks one eye at a time.  There is not
of the ghosting you get the polorazied glasses.  The sync signal comes in
over the radio receiver.  I saw a movie in the NYC theater a year ago on a
field trip with the NE Photo Historical Society.

I just took my first roll of Franca beamsplitter photos using a Nikormat FT
with 50mm f2.0 lens.  I took them to Konica for a set of 3x5 prints, a proof
sheet, and a floppy with the scans on it.  The normal 2 days service took 7
days in this case.  I found out why -they carefully printed just the right
half-frame image.  I saw that but took the package home with the hope that
the scans would be of the full frame.  No luck, they were also of the right
image.  I guess it is my fault in not writing special instructions to
process as full frame.

I am going to take the roll over again because there was flare from the
flash getting into one of the mirrors.  The outside photos were fine.  This
beam splitter needs a large lens hood to block out the flash.  I am taking
photos of some of our cats using a shoot-through umbrella which was quite
close to the cat on one side.

I didn't see any double image due to the Franca not using front surface mirrors.

There will be a photo-3d page as soon as I get these cat photos scanned.  I
hope to have both b&w anaglyph and color wall-eyed pair type in the page.
