Re: Anyone use 120-film stereo pairs?

  The images are 6x6 which are about 52 x 52 mm in reality (if I
recall the 52 correctly).

  I'll let Joel answer about his Sputnik since I don't have one (yet?).
But I did buy a Ricohflex TLR a few months ago.  I have taken two
rolls of slidebar shots with it. I was in a stall for a while since
mounting was difficult (compared to Realist with Albions).

  I just finished building myself a light box. So now, with my
mounting guide, I can properly mount what I shoot.

  Do you have a slide bar?  I posted about my slide bar a few months
ago. You could do a search on the archive or email me for it if
you need to build one.

  John B has built a proper viewer and there are plans on the 3d web
site.  Que Vu (sp?) sells the King Inn viewer. Supposedly has
fluorescent lighing but poor lenses.

  I slapped together a temporary one using two magnifying glasses and
some hardwood.  The magnifiers are 1.75" dia and 2.5 power. This is
not the "correct" focal length but works okay (except for colour
fringes) until I buy the proper achromats (from Edmund Scientific
or somewhere cheaper).  I have some opal plexiglass as the diffuser.
(Make sure you put the diffuser a bit behind the slide so the dust
is out of focus when looking at slides.)

  If you want details email me.

  80 to 100 mm is probably good. The same fl as your camera gives
ortho.

  If you get the MF mounts that Joel sells (which are very nice
[no fuzzies] and fairly cheap) the images are 2.5" centre to
centre so you can even free view the slide. Lenses help you see the
detail though :)

  Joel is going to have a 645 mount soon, then you can crop out
excess sky or blurry foreground if desired. Or use a 645 camera :)

  Wow that's a bargain. I paid $50 CDN for my Ricohflex but you got
a better camera for only slightly more.

  If I could find a second Ricohflex I'd buy it in a second. Slide
bar is fine for stationary objects but you'd be surprised how often
the wind is blowing, clouds are moving, bird fly into one image when
you take slide bar shots.

  A pair of MF cameras on a slidebar would be ideal in my opinion.
Move them as close as possible for near ortho shooting, move them
apart for hypers. With the twin cable release that Reel 3d sells
you could probably get pretty good syncronization.

  A Sputnik has its advantages too. Joel can describe them. But
if you have the money a Sputnik and a pair of TLRs would probably
do most everything you want.

>would have to be upside down to be wound.... hmmm... could be trickier than I
>thought... never mind!

  With two sliders on a slide bar just move them apart to wind then
back together to shoot.

>who when and what?  Did I leave anything out?

  One question I have is does anyone here have the King Inn
medium format viewer. Could you describe it and tell us
how good it is. (It sells for about $130 I think.)
