Subject: 35mm cardboard for chinese viewers?
Date: 2009-03-13 14:05:12
From: David Richardson

Hello,

No doubt this will go over as well as bamboo shoots inserted under nails but...

I'd really like to have or get a pattern for cardboard to use stereo pairs shot via 35mm camera paired arrays but to be viewed on the 3dworld hand held viewers. I own far more matched lens pairs in 35mm than any medium format cameras and the viewers seem to have a future unlike the franka or any other 35mm system. With China seeming the best non-RBT or (insert a 35mm system name here) format. One could view the small and medium formats via the hand viewers and not loose too much. I met a fellow at Boise whom was doing 35mm in the chinese system and hope somebody can get this request to him.

Thanks.

I read this a couple of times and I am still NOT sure what is being asked
here....

Can you try asking again, more to the point?

George

He's asking if anyone has a way of viewing 35mm stereo slides in a
Chinese MF3D viewer.

When I had a Saturn viewer I looked at a few full frame 35mm pairs (in
normal non-stereo 35mm slide mounts) by putting the 35mm slide mounts
in the openings of a square (50x50mm) cardboard MF3D slide mount. I
only had a few 35mm stereo slides (test shots I used to compare the
same scene shot with 35mm full frame and 6x6 MF), so it wasn't
something I was planning on doing for a lot of slides.

My guess is he's looking for an MF sized cardboard mount wth apertures for 35mm, so he can view it in a 3d world viewer . You could probably get there by masking MF pano mounts, but i wouldn't want to mount those. Alignment could be dicey.

Maybe he could make a holder, out of an MF mount, that would suspend an RBT mount in the viewer.

Despite all his social commentary, I don't see the point....

Even if he could find such mounts, he will be using an unnecessarily large
viewer with low magnification (big disadvantage), and large mounts (waste of
material and space in storage, difficulty in aligning the film chips).

Why?

Because there is an amble supply of Medium Format viewers? Yes, these
viewers have nice lenses but the focal length is way too long for 35mm
stereo (low magnification).

If the viewer is the issue, would it be easier to use something like this
channel viewer?

I am working on a batch of 25 viewers. These have nice achromatic lenses,
50mm FL. They are compact, simple to use, as good as the hand-held MF
viewers, but much smaller in size.

The RBT mounts are incredibly easy to use, flexible (will accommodate all
types of 35mm stereo). The supply is stable and reliable.

I honestly don't get it.

I agree with every thing you said George.

The only reason I can think of to do that is if one
has one of the MF viewers and doesn't have a "proper"
35mm viewer and wants to do viewing at little
to zero cost, not wanting to invest in 35mm format
equipment.

The MF viewer would be non-optimal for
reasons you have already mentioned.

Thinking about this a bit more, it starts to make some sense, if you want to
keep all your stereo images in the same format.... and take advantage of the
quality, price & availability of the 3d World viewers.

If it were me, I would try to make an adapter to accept the 35mm slides
inside the MF viewers.

BTW, the reverse (mounting MF images for 35mm viewing) was done by Dave
Klutho, who mounted MF slides in super-slide 2x2 mounts (regular 2x2 outer
dimensions with 40x40mm openings) and viewed them in a "Combi" 2x2 viewer.
This was before the MF viewers were readily available.
