The Nishika camera's work the same way as the old style of 3D baseball cards
or postcards.  The print has a lenticular screen laminated on the front. 
(Well, actually, the photographic emulsion is painted on the back of the
screen...) then printed so that when you look at it from ONE angle, you
only see one image (of the FOUR the camera takes).  Since your two eyes
are looking at the print from different angles, they see two different
images and thus they percieve a 3D image.

I don't think this process gives as good a 3D picture as one of the more
traditional 3D cameras (NOTE: the Nishika is FAR from being the first 3D
camera, and isn't even the first for making 3D p[rints.  The Nimslo takes
that honor.  The Nishika is a kinda cheap copy of the Nimslo.  If you were
DYING to have 3D prints, I'd get a Nimslo.  They have much better lenses and
automatic exposure.  The Nishika has plastic lenses, an oversized body with
a lead weight in the bottom, fake LCD display on the top etc etc.)

For print stereo there is also the Image tech camera (forget it's name right
now, used to be called the TRILOGY since it has 3 lenses instead of 4)

The trilogy sells NEW for $150
Nimslo's are available used for about $100-$120
Nishika's are commonly available at camera flea markets for about $100 (new,
	but without the flash or video tape)

There is also the Loreo camera (from Reel 3D enterprizes) which costs about
	$120.  It takes two pictures side by side and requires a viewer.

You can also go back to the 1950's stereo cameras.  The most commonly
found are the Stereo Realist and Kodak stereo.  They cost between $100-$150
depending on their condition (cosmetics, something for that price will work).
They are mostly for taking stereo slides which can be viewed with either a
hand viewer or a stereo projector.

If anyone is interested in getting into stereo photography, I wouldn't
recomend a Nishika as a way to do it. (Unless you want to do ONLY print
stereo and can get one REALLY CHEAP.  For print stereo they actually do an
alright job since the printing process is the limiting factor in qulaity).

You might also want to subscribe to the stereo photography mailing list.
Just mail to: listserv@csg.lbl.gov    
with "subscribe photo-3d <your name>" in the body of the mail.
