[photo-3d] Re:Projection

["seymour goldberg" <segoldb@xxxxxxxxxxxxx>]

I seem to be having trouble focusing the last set of slides I took. I used
the Kodak Stereo Camera, and projected using the TDC model 116 projector. I
have 4" f3.5 coated Anastigmat TDC matched Tridar projection lens' in the
projector. I recently obtained these.
 Is there a right and left lens?
If so, where and how are they marked?
I moved the screen in so that is is 9' from the projector and I got a better
focused image.
I moved the left lens out a few turns then focused with the knob. I also had
to move the right lens all the way in to get it to focus properly.
P.S. The picures were perfect using a hand viewer.
Thanks,
Sy
