Sorry if this is a duplicate posting - I tried posting directly from the
Onelist web site and it didn't seem to go through

If you don't have infinity in the shot you can get surprisingly close with a
6" separation, especially using 28 mm lenses.  I've recently been
experimenting with putting the left XR-10M partly behind the right one. 
This gives me a lenses separation of 3 3/4", with the left lens 2 1/4"
behind the right one.  Using 28mm lenses I've taken lots of nice "people"
shots at distances between 5 and 10 feet.  At 10 feet I can't detect a
difference in the size of the two images.  Closer in the right image is
slightly larger, but not enough for me to notice in a Red Button or Holmes
viewer.  Of course custom prints or digitally manipulated images could be
adjusted to match exactly.  

I've put an example of this in the "XR-10M sync" folder in the Onelist
files.  The URL is:

Using this technique I can now use the same twin XR-10M rig for hypers,
scenics and family shots.  Jim Harp
