Materials cost about>$20 CDN per roll (film, processing, mounts,>silver tape). 4X5 dupe film is a very practical option. Depending on how you crop, it is at least possible to get two sets of MF stereo pairs on a single sheet. Coming up with a special film holder mask shouldn't be too hard. In camera duping works for still life shots, but perhaps only if your camera is fine tuned enough to have a perfectly exposed image. I hate to admit it, but I still lose far too many shots from erratic shutters,bad focus and light leaks. Perhaps the market may be in duping MF stereo slides instead of selling them!

  I have been playing with duping  for the last 4 months and Yes you can dup MF, but you have to use 70mm Kodak 5071 dup film. I have a Bowen set up with a 70mm back onto a Hass with a old Hass bellow and using a 90mm APO enlarger lens. If you want the sharpest image, you just have to use a APO lens. I also found out that it does not make a bean of a difference if you use strobe or tungsten for the contrast, but the strobe will give you a sharper image. To make a Bowen to work with a Hass, all you have to do is turn  the bracket, for the bellow, around backward. You can see my Bowen set up at:

If anyone, want one of these Bowen, I am selling my extras for $300.00 each, with cheap or without cheap lens. That how I got them, and they are design for 35mm dups, but you can use a copy stand over the base of the Bowen duplicator. Using the Bowen as the power source, it has the most power of all the duplicator, you can shoot it at f/32+ or shoot it at f/8 at 1:1. You can still get it new or buy parts at Calumet, it is the model 35c.
