Keep in mind that MF3D has several different formats.  The smallest is 4.5 x 6 cm (per eye-view).  The most popular is the square 6 x 6 cm.  A step up from that is the 6 x 7 cm.  There were a very few 6 x 8 cm.  Then, what in my opinion was the most impressive, the large 6 x 9 cm.  I used a pair of lantern slide projectors to project those.  Wess mounts made a 6 x 9 plastic mount (mono).  A pair of those fit in the two lantern slide projectors, since the outside dimensions of those mounts was 3-1/4 x 4 inches, the same as standard lantern slides.  They could be rotated for either portrait or landscape formats.  Yes, custom viewers could also be built for that size. I made one several years ago.

*raises hand*

Film shooter.
Though I shoot both 35 mm with my Realist and Medium format with my trusty "souped up" Sputnik. : )

MF slides viewed in a viewer is priceless. Even in my poor Holga 120 viewer.
I need to get a decent viewer!
I also shoot 120 BW negatives for contact printing, though I haven't gotten around to do that yet. I just developed my first rolls BW though, an amazing experience and tingly feeling seeing the photos appear when opening the development tank.

35 mm slides from the Realist is also very nice in the Realist red button viewer, but definitely a smaller view.

The saying goes, if you haven't experienced MF3D slides in a decent viewer, you haven't experienced real 3D. : P

Can be argued of course, but it's hands down the best I have experienced so far and I would want everyone to try it.

Hi Jack:

There are quite a number of people still shooting film.  All of the film shooters I currently correspond with are shooting medium format slides (usually 6x6cm on 120 film), as do I.  MF3d is the ultimate upgrade from viewmaster format.   We have our own yahoo group too!

I will dare to venture that we have more people shooting MF3d film right now than 35mm..  I think that because at the meetings (3D-con), I hardly ever bump into people that are showing off their latest 35mm creations, but I see lots of new work done in medium format.  Let's see a show of hands: who is shooting MF3d, and who is still shooting 35mm slides?

We MF3d folks shoot with cameras ranging from the venerable Sputnik, usually "souped up" in some ways, to the relatively modern Chinese "3-D World" cameras, to various flavors of twin-rig (e..g. Hassy's or Mamiya's), and also cha-cha.  MF3d stereoscopes are a major challenge to find, but occasionally someone steps up to the plate offering a nice viewer of more-or-less custom manufacture (cue Larry Heyda here).

For fine art shooting, the luscious tonality, color and level of detail can't be beat in MF film format.  I'd say, if you want to move up from Viewmaster, skip 35mm and go straight for MF3d!

cheers,

Boris

John,

You say you made a viewer for twin 6X9 transparencies.  Did it only work for portrait format?  Or did it have prisms (or something else) to accommodate the images being separated more than your eye spacing?  Or was it a Wheatstone type?

Show of hands?  I'm overwhelmingly shooting in 35mm with the Realist.  I agree that MF is a superior experience, and have played around using a Pentax 67 and slide bar, but the ready availability of affordable viewers, projectors and other gear makes the Realist format the best overall for me.  The 6x7 format gives me room to adjust the stereo window when using 6x6 mounts, though I'd love to have a proper viewer for 6x7.  When the 3D World camera came out, I was very interested, but the more I looked into MF3D, the viewers always seemed to be the weak link in the chain.  

If was a machinist or better craftsperson, perhaps I could build a viewer that I feel does justice to the quality of the images.  In the meantime, I'll play around with it and learn from you folks who are really doing it.

Larry Heyda makes an excellent MF slide viewer, so that complaint is gone. https://larryeda.m.webs.com/
 True, there is no projector, but if you want to project, you will lose all the high quality you are paying for. You are better off shooting digital and showing on a stereo TV.
I stopped shooting 35mm when I just shot far too much film to mount. with MF you really have to carefully select your subjects or it's just too expensive. Result? Better images, less waste.
When they make a cell phone with an 8k screen, I may stop shooting film.

Actually, I have a MF3D projector with carriers for a couple of mount formats...

But it's big and clunky and I very rarely use it.

As Timo says, there's little point unless you have a huge screen... The projected image from a good 35mm pair looks just as good on "normal" (up to and including the screen size used at e.g. NSA Conventions.) screen sizes as a MF3D slide does...

We had MF3D projection at the NSA Convention in Buffalo some years ago. It was hoped to have a really big screen for the medium format, but we couldn't get it truly flat so MF3D was projected onto the standard screen.

I had designed a "hybrid" show that started with 35mm slides projected with the RBT projectors then changing to MF3D at an appropriate point in the show. The soundtrack was the track "Playing with the Big Boys" from the animated film Prince of Egypt... Sadly, there was not the size increase that I had expected so the MF3D just looked like a continuation as before...

Message: Don't bother with MF3D projection unless you have a silver painted house side to project on!

You may find this of interest: http://phsc.ca/pasquarello-2.html   A show I presented to the Photographic Historical Society of Canada a few years back. The photos were made with paired Hasselblad X-Pans .  The screen (s) are two square ones with a strip of sheet metal between held in place with many small magnets.  The sheet metal had silver screen material laminated to its surface. It works surprising well,  in fact Bob Bracket and I gave a workshop at the Buffalo convention on doing this screen hack.

Back in the eighties, I use to correspond with a guy by the name of Daniel Greenhouse.  He made a 6x7 stereo camera as well as a Wheatstone-type viewer and even a projector to view his slides.

I just checked the net and he's got all the info about them on his website:

http://www.ghouse.com/daniel/stereoscopy/equipment/index.html

I remember the problem was that the image-to-lens distance in the viewer was too long for a wide angle view.  I was looking for more immersion - such as the LEEP viewer could provide.

6x9mm sounded nice but it also limited the minimum interaxial possible on the camera.  6x7 seemed like a good compromise so I joined two friends to design a  6x7 camera which was built around 1992.   But we never got around to a compatible viewer !

Shooting straight ahead with parallel cameras (a pair of Optika IIa models) the minimum stereo base was a hyper 127mm.  So, I aimed the cameras toward each other and shot the reflections off of a pair of 45-degree front surface mirrors, like Natural Vision.  My preferred lenses for this configuration were the 105mm Voigtlander Apo Lanthars.  As I recall, this gave me a minimum stereo base of about 50mm.

Good solution, but we wanted a very portable camera - as compact as possible - and also a wide angle one.  The cameras were outfitted with 47mm lenses and the interaxial was 70mm.
