I would like to try shooting some slide bar or hyper stereos with my Fuji GSW 690 III, which has some super sharp 65mm lenses. How do I view the images other than freeviewing? Are there any mounts or viewers that accomodate an image that size?

Thanks
Nik

The 90mm wide images exceed eye spacing for everyone I've
ever seen. This means that there isn't any way to build a
simple optical viewer for this size. By "simple", I mean
lenses only with no mirrors or prisms.

To view 6x9 slides, you're going to need to build something
like a Wheatstone, or tri-delta viewer.

I know John Roll shoots 6x7 with his Mamiya. I understand
his preferred viewing method for these images is projection.
I'm not aware of any projectors for 6x9.

Buhl optical made 6 X 9 projectors for the US military,
they show up on surplus markets sometimes.

P.S. I believe I've seen pictures of John Roll's 6 x 7 viewer
it is a "Wheatstone" design with built in light tablets behind
each transparency.

Oh, and.... more "P.S."

I've shot 6 X 9 in vertical orientation on a slide bar
that way you end up with a "transparency cabinet card"
(you'll have to cut your own mounts!)

A standard Holmes stereocard is 3.5"x7". 180mm is just over 7", so with slight cropping, it should fit nicely on a stereocard size mount. Vertical height and magnification may be low. Then modify a Holmes viewer with a translucent light source.
This would be easiest. Though the vertical idea would be good also.

John Thurston gave a reply which I am in total agreement with, "the 90mm
wide images exceed eye spacing for every one I've ever seen. This means
that there isn't any way to build a simple viewer for this size."

Apparently John and I are behind times, as about 2 weeks ago I did ask
Bill G.I, (a self implied, Guru, on the latest in MF technology), "how
is it possible to view a 3d image, in ortho, taken with as 47mm lens
-when the image is 69mm wide. the simplistic - (no details included),
answer by Bill G' was -..."through a loupe/mirror system, scan and
resize.' I considered the answer to be a non-answer, of little or no value.

IMO, Nik Skharni should contact Bill G. and inquire for more details, so
that he will be able to view any, future, 6 x 9 3d images in ortho 3d,
apparently using the latest, "loupe/ mirror system, along with latest
digital scan and re-size equipment", as mentioned by Bill G.

Being digitally illiterate, I can only assume that Bill G. does know
what he is talking about, though I do have some doubts.

The very best,

DON

Thanks
For the replies
I will try shooting on a slide bar and free viewing the resulting images

Remember Don, just because you do not understand something, doesn't make it untrue.... I
know that is a hard pill to swallow....

You have had lots of doubts about everything I write Don, but when I challenge you, to see
just how strong your convictions are about my false statements, and offer you cash if your
doubts are valid..... you put your tail between your legs and run-off. What does that suggest?
