Five Steps to taking your own  
3D Stereo Pictures

1] Create the stereo camera. Use white glue to attach two "single use" cameras together, bottom to bottom. Two rubber bands are used to clamp the cameras together overnight.  Establish and "mark" the cameras left and right. 
2]  Take the stereo pictures. Hold the two cameras such that the right hand holds the right camera in an "overhand position" with the right finger on the shutter release. The left hand is positioned in an "underneath position" with the left finger on the shutter release. Pictures are taken with the cameras in the portrait orientation.  Remember to keep the left and right camera orientation. This will facilitate step 4. 
3]  Process the stereo film. The processing is exactly the same as normal processing. Ask for "wallet size" prints.  Wallet size is more convenient for the magnification of my stereo viewer. 
4]  Assemble the stereo pairs. Use a "glue stick" or "double sided" clear tape to attach the left and right images to a 3 by 5 index card.  It is not necessary to use the index card, but it makes the transport, quick alignment, and viewing much more convenient. 
5]  Purchase, or create the stereo viewing glasses. I have always used the glasses for airphoto terrain analysis. (Available from Air Photo Supply Co. in New York).  These glasses are expensive and not appropriate for every situation.

Where do I get the special glasses?  

I recommend using two large magnifying lenses!  

Two magnifying lenses are a bit difficult to manage, but with practice stereo viewing is quite easy. Initially, try focusing one eye-at-a-time..., then let the two images "converge" together!
