I have included file sizes in the image links.  Please take a moment to check these sizes before you begin downloading images for viewing.  Several of the JPS files are very large and will be painful to download over a modem link.

The images are presented in cross-eye and anaglyph format.  If you prefer a different format or size, please give the Stereoscope applet a try.

Java Stereo Viewer

Many of these pages use a Java Stereoscope applet by
Andreas Petersik
. It made a Java convert out of me and I highly recommend it.

The A5 story 

I chose to use a Canon PowerShot A5 as my base camera.  My reasons were several:

  • Photo copyright Canon USAThey use compact flash media (for which I already own a reader)
  • They use a rechargeable battery (for which I already own a charger)
  • They are small and light (so when I have a pair of them I can still carry and control them)
  • They take nice pictures
  • They have a pretty wide 5 mm (38 mm equivalent in 35 mm camera terms) lens
  • They are non-zoom (so I don't have to synchronize lenses as well as shutters)
  • They shot at about ASA 400 in their low-res mode
  • They have a metal body put together with screws

With all that in mind, I started shopping USENET and e-bay for a pair of A5s.  I was able to find a couple of cameras in very good condition for a total of $350.  

As each of my "new" cameras arrived from their previous owners, I confirmed that they were functional and had good optics.  Everything was great until I started taking test shots with both cameras.  I was stunned to discover that the two cameras were aimed differently.  Both had their lens/CCD assembly aligned with their view finder, but when set on a horizontal surface (or mounted on a tripod) one took pictures several degrees higher than the other.  To correct the misalignment and create usable pairs from my twin,  I would have to:

  • edit each resulting pair to correct the alignment
  • shim the camera bases to bring them back into alignment
  • buy more cameras until I found two that lined up nicely

I chose the third option and with one more camera, I scored with an excellent alignment match.  Further investigation revealed that the winning pair had serial numbers much closer together than the loser, but whether that represented information or was just coincidence, I don't know.

My camera choice was made late in 1999 and early 2000.  Many things have changed in the digital imaging world since then.  In mid 2002, I decided to make a new twin and chose to base it on the Canon A100.  Its firmware offers many great features not found on the A5 with slightly improved image quality.
