P3D RE: P3D More Medical Stereo Photo Questions

["Greg Kane" <pgwhacker@xxxxxxxxxxxxx>]

The Realist has a built in stereo window at 7 feet.  The exposed area of the film isn't directly behind the lens, it's offset a
bit.  Anything shot closer than 7 feet will need to be trimmed (prints) / adjusted(slides)  if you mount to the window.

With prints you have the option of trimming away the _bottom / foreground_ and preserving the full width of the picture.  There's
an example of this technique on the APEC How To Make a Stereograph web site
http://home.earthlink.net/~pgwhacker/APEC/HowTo/HowTo.html   on one of the brown backgrounded pages.
