P3D Re Realist Realorama

[Peter Homer <P.J.Homer@xxxxxxxxxxxxx>]

The Realist Realorama is obviously not the device I described in reply to
Mark Shields post judging from other members replies. What I described
would seem to be the Sawyers ( viewmaster?) Bi-lens  and its clone the
twin-lens mentioned by Rod Sage. Mark Shields description of it seemed to
be the Bi- Lens.

Actualy I have some of these viewers but I dont recall the name Realist on
them.
Some have the added feature of being able to view film strips which run top
to bottom across the viewing slot so that you have to try to like around
with either or both eyes to see the image! One way that they do seem to
give a genuine stereo view is with untransposed Nimslo close up pairs
mounted in a normal 35mm mount. The concave mirror would seem to do the
transposing.
Colin Clay demonstrated a genuinely stereo version he had made for realist
format which had two mirrors a septum and a light source built in, at a
meeting of the midland branch of the UK stereoscopic society. Follwing that
I made one from one of mine by cutting the mirror repositioning to the two
halves and adding a septum, for transposed beamsplitter pairs, I also found
if I toed the mirrors in without a septum it made a better transposing
viewer than just the single mirror
