Re: Steinheil WideAngle attachments

Paul....I think one has to realize that these "afocal" attachments are
basically crappy regardless of who makes them. The most expensive ones were
the Rollei Mutars for the AutoRolleiflex..even then suggested use at f/5.6
and beyond. But knowing this then
any afocal might be about equal and a local stereo dealer I see at shows is
selling
the afocal attachments meant for viedeo in pairs on Realists etc. as
sustitute "Steinheils Wide Angle" attachments. Presumably the Steinheils were
"matched" if such is necessary, but who knows? There were a lot of these
things also made for the Japanese fixed lens cameras that cover more than the
movie or video types..i.e. longer focal length lenses.

Jon...on the level? Well you can tilt a stereo camera all you want fore and
aft (ie.look up and down) but one sure should keep the lenses parallel to a
horizon level so the two images have the same vertical field...for ease in
viewing. BobH
(I guess if you held a Realist vertical..you would have to view the result
with a Magic Viewer???)

You'd have to cut the Polaroid prints in order to view them with an
antique-style stereoscope. Isn't that considered a bad thing to
do -- releases chemicals onto your hands or something like that?

But you could tape uncut Polaroid shots together to view them with
a View Magic viewer.

After someone on this list said that Blockbuster Video rents these things I
just went out and took advantage of it. As it was stated just $10 gets you
the unit and two games for three days (plus a $150 deposit). The unit has
interpupillary adjustment and focus adjustment, with a screen to help in the
adjusting. The sound is stereo with a headphone jack available. The only
thing about the sound is that it gets really monotonous after a while. The
Tennis game is well done, considering the limitations. The title screen is
full 3-D (meaning the letters actually have roundness, not just a cutout
appearance). The game image itself is of the cutout variety, with the court
outlines showing very good depth. I think they did a good job on the stereo
imaging. The Tennis game is even easy for someone my age (prefer mechanical
pinballs) to learn. The lenses are not perfectly sharp over the entire
image, as you need to move your head a little to sharpen up the corners and
top and bottom.

The Wirgin stereo camera (also known sometimes as the Edixa) came in two
models I think. The difference being one was a basic camera and one had a
rangefinder. I have a Wirgin 1A basic stereo camera. It was the first
stereo camera I ever had. It is an excellent camera, very sturdy (all
metal), heavy, easy to handle, and very friendly controls. The lenses are
excellent as well. They produce superb sharpness. One really good thing
about it is that you can use modern elect. flash with no access. or mod's.
The shoe on top (probably for a rangefinder originally) fits a flash
perfectly and the synch. connection is a modern elect. flash style. Just
shoot at 1/50 sec. for best results. Many other stereo cameras require
adapters or mod's to use modern flashes, but not this one. There is one
weak point with some Wirgins and Edixa's; the film advance sometimes produces
overlapping images. On mine this was due to a worn ratchet pawl inside of
the advance mechanism. A local camera repair shop (not specializing in
stereo) fixed it for $45. It has worked very well since then. It is my
favorite stereo camera to use, and I have lots of cameras (not collecting
them, but using them!). I wouldn't pay a premium for one, but if the lenses
are clear and the shutter and diaphragm work smoothly it makes an excellent
camera, very easy to use. If possible, before buying, put in a roll of film
that you can waste and test the advance mechanism. Mine acted up around exp.
#15 or so and would produce a noticeable snapping feel on the lever when
advancing( it takes three full strokes of the lever to advance one frame
number. A copy of the manual is available from Reel 3-D.

PS: Debate gizmos as you must, but the retina-searing,
POLARIZED autumn shot I saw in the GAMMA SSA folio a few
months back CANNOT, and WILL NOT be approached with
conventional, unfiltered stereo cameras. That is unless you
catch BRIGHT sulight against a dark and stormy sky (about
twice a year where I live).

PPS: I've seen a few of Jon's pix (and even own a couple :-)

If it uses the Virtual I/O gear, it's 30 two-field frames per
second (i.e., 30 images for each eye). It's flickerless
because it uses a frame buffer for each field, so that
neither eye has a dark phase in the cycle.

Josh

P.S. - Actually, as I think about it, it may be capable of
faster frequency. The demo of the glasses I saw used
a VHS tape.

Alan Lewis writes the following regarding the Wirgin stereo camera:

>The lenses are excellent as well. They produce superb sharpness.

Superb, compared to what? A Nimslo or a Realist Custom? I still think
that most better-known stereo cameras (Kodak, Realist, TDC, etc.) at f8
or less produce sufficiently sharp pictures to the point that one cannot
tell the difference in sharpness when viewing with a good quality
viewer. When I started using Fuji Velvia, I then realized what "superb
sharpness" is all about. But it's in the film, not the camera.

Why 1/50 and not 1/100, or anything else?

>It is my favorite stereo camera to use, and I have lots of cameras (not

It is a personal observation that everyone's first camera is their
favorite one, which says a lot about how unimportant differences between
these cameras are. But why do you use lots of cameras and not just your
favorite one, assuming, of course, that the other cameras are of the
same format?

I've seen an ad in the latest issue of NetGuide magazine (2 page ad).
As far as I know from Nintendo Press Releases, it's stereoscopic.

This is a true statement about the "retina-searing" combination of Fuji
Velvia and polarizers in general. Somehow, I feel that Alan Roe who took
the picture used a custom-made polarizer attachment and not the SETON one.

The problem with using a $500 attachment on a $100 camera is that you will
be more concerned about protecting the attachment than taking the picture...

Subject: 3D-MAX and other video stuff
Message-ID: <950831205754_726...@CompuServe.COM>

I have been put in the unenviable position here of having to field some
technical questions about the 3D-MAX system when I'm afraid I'm not a techie
type and don't really have the answers (their literature is also a little vague
on technical matters). All I really know is that the system works well on my
not-terribly-sophisticated 486 S-VGA system. In response to one question, the
specs on the box do include the Tseng ET-4000 W/32 series, along with video
boards from Trident, Advance, S3, Cirrus Logic, Western Digital, and ATI. The
company's telephone in Korea is 82-343-85-8500 and their FAX is 82-343-86-7205.
The woman in charge of overseas sales is Cathy Chang, and I have found her very
responsive, if slightly slow, to answer my questions.

In further response to the question someone had about getting sequential field
3D videos for use with the Virtual i-O system, the primary source that I know of
is 3DTV Corporation at P.O. Box Q in San Rafael, CA 94913-4316. They've got a
number of 3D videos, including some of the smaller PD titles from the '50s and a
bunch of stuff from the Orient. They also sell sequential field viewers,
although they have been known in the past as having pretty exaggerated
prices--this seems to be changing, however, as more competition looms on the
horizon. Some kid on alt.3D was was recently actually talking about how cheap
they were in comparison to 3D-MAX (which he thought was outrageously priced at
$200). You know how the kids in the alt groups are--if you won't give them
something for free and they can't figure out a way to steal it from you, to hell
with it. I haven't seen 3DTV's catalog recently, but in the last one I did see
you couldn't get much of anything under $1000!

Actually, it sounds like a great effect to me. I have often used photoflood
bulbs in place of normal light fixtures for extra "natural" light in movie
sequences. When the light appears to be coming from logical places, it gives a
much more realistic feel to a scene than when the light "source" casts a shadow
behind it!

Message-ID: <9507318099....@reichhold.com>

I've seen a lot of "attitude" in postings of late. IMHO, there seems
to be a more than a little resentment toward those fortunate enough to
be able to afford better equipment than others.

The rationalized cop out is that the hardware is not important. The
creative aspects are what its all about. That's a truism. Agreed.

But why should an artist not use the best tools he can have access to?
Granted, a great artist with the most rudimentary tools will outshine
the dolt with state of the art equipment. But that is really an
irrelevant concern. Why bother with that sort of comparison. At the
top of the heap, the real question is "does the artist benefit from
using better (the best) tools." You bet he does. I might be able to
play golf against John Daly if he used whiffle balls (He would
probably still outdrive and beat me.), but he would certainly be
limiting his true potential. If the tools allow the artist to express
himself in a fuller capacity, even if it increases his artistry only a
trifle, it is worthwhile.

As both a novice computer user AND a novice Realist camera owner, I've much

past week - BUT when I've tried to download documents like the FAQs and the
products and services lists by accessing the http://www.tisco.com/3d-web

proper ftp address - and sure enough, I do lack same. Can someone help me log
onto the photo-3d bulletin board or website directly and/or provide the
proper ftp info to let me download these documents? Thanks in advance.
Now for the information: An adult video company by the name of Vidmax is
about to start a BIG push for its new 3D videotape line of XXX rated
features. They use a Toshiba 3D video camera for recording and shutter
glasses with an adapter box for viewing, and I understand there is great
interest in the video retailer community for this process. The company has
also manufactured a six-foot-tall 3D standee of a pretty, bikini-clad girl
wearing the shutter glasses to use as a point of purchase display. The tapes

The area is very famous for fatal avalanches in the winter. I don't think (but may

There will lots more news on the Virtual Boy at E3, the Electronic
Entertainment Expo, which starts May 11th. In fact, we'll be releasing all
the latest developments on Virtual Boy on May 10th, so the first place to
hear the news will be right here. So stay tuned for information on games and
other details.

Virtual Boy is a stand-alone RISC-based, 32-Bit video game system that uses
two high-resolution, mirror scanning LED (light emitting diode) displays to
produce a 3-D experience unlike anything game players have ever seen. Its
unique design eliminates all external stimuli totally immersing players in
their own private 3-D world.

It is a sleek, rectangular unit measuring 8.5" long by 10" wide by 4.3" high
and is supported by a table top stand. It is operated by a new
specially-designed double grip controller which is connected to the head set.
The cartridges will be slightly larger than Game Boy Game Paks, and are
inserted into the main unit.

The only remotely comparable products are VR goggles for PC's that cost
between $500 to $100 and still require an expensive computer to run the
software. Virtual Boy software exists on Game Paks. You'll insert them just
like plugging in Super NES games. It's a portable system, but it's not a big,
new, Game Boy. It's totally unique.

Looking into the Virtual Boy's viewers is like entering a world out of
science fiction. The sense of real 3-D space is the most striking phenomenon.
Don't expect the shallow depth of holograms or printed 3-D effects, but a
true stereo image in high-resolution red and black. The depth seems totally
real, like stepping into a miniature world. Objects and characters have
fullness. They turn and move in three dimensions. The red and black images
give the virtual world even more of a sci-fi look. And the smoothness of the
animation is beyond anything you've seen--well, other than
reality itself.

-----------------------------------------------------------

The technology for Virtual Boy was first developed by Reflection
Technologies, a company founded in 1987 by a team of scientists from MIT.
They started the company to exploit a breakthrough in LED (light emitting
diode) technology. The resulting designs and products carry multiple
worldwide patents, have been extensively tested and can be manufactured for
the mass market.

Nintendo has exclusive worldwide licensing rights within the video game
market to Reflection's patented virtual display technology, and that's what
we're using for Virtual Boy.

Nintendo has invested money in this company. "We have made this significant
investment in Reflection because we recognize the tremendous market potential
for the company's unique technology," stated Nintendo Co., Ltd. President,
Hiroshi Yamauchi. "In addition, our licensing agreement with Reflection will
make Nintendo the only video game manufacturer with access to its unique
technology."

"We are very excited to be working with the worldwide leader in the home
video game industry," commented Al Becker, president of Reflection. "Our
brain-trust at Reflection has been working on this technology for a number of
years and this exclusive worldwide licensing arrangement with Nintendo will
place our technology into the hands of millions of consumers."

"The cutting-edge technology developed by reflection Technology has multiple
future applications in the real world, such as telecommunications," said
Nicholas Negroponte, who is Director of the Media Laboratory at MIT and an
investor in Reflection. "Utilizing this technology, Nintendo's Virtual Boy
will provide video game players with a truly unique experience."

---------------------------------------------------

So how does this work?

Virtual Boy uses two miniature LED displays, two oscillating (vibrating)
mirrors and two focusing lenses to create the impressive 3-D effects. The
vibrating mirrors focus the dual images through a small range which your eyes
interpret as a single image with depth. By moving the two images closer
together or further apart, using an effect called "parallax," the image
appears to move closer to you or further away.

So by moving the reflection one way or another, we can create 3-D images.
It's sort of like looking through binoculars. Although each eye looks through
a different lens, you only appear to see one image. The two screens of the
Virtual Boy also appear as one image, but each eye is actually looking at a
slightly different image. That's how the 3-D effect is created.

Since I might be one of those with the "attitude", I might as well
respond to this.

If you are one of those fortunate artists who can afford the best tools,
that's fine. Buy them and use them. But, if you are working, like most
of us, under financial constrains, then the question of what to buy with
your limited budget is a very real and a very important one. And it is
this question that we are trying to answer.

I want to stop people from thinking that the reason that they don't get
good results in their 3-d photography is the lack of expensive
equipment. There is a lot that can be done with inexpensive stereo
cameras and most people don't even reach the full potential of these
instruments. So, instead of worrying about what you don't have, try and
do your best with what you have.

Also, for beginners: Doing good 3-d photography has never been easier
or cheaper. A $100 stereo camera will be the best investment you've
ever made. Sure, you can build up your equipment with time, but nothing
will ever give you more value for the money than that first $100.

Too often, things get passed by and overlooked without being appreciated. I
would like to thank all of the 3-D enthusiasts who use this board and share
their knowledge with the rest of us. A very special thank you to Bob Weir,
John Bercowitz and Elliot Swanson for monitering and handling the overall
system so we can have this wonderful exchange of ideas and opinions.

There are many technical aspects of 3-D that are beyond my ken but I still
read 98% of all the postings and enjoy 100% of them (yes, even the debates).
As a collector my realm of experience is somewhat different than many
others but it's always great to share ideas and its nice to know so many new
Internet users are coming on line with us.

Once again, thanks to each and every one of you!!!

Isn't 3DTV on the suppliers list? I think their tapes would be
compatible with the i-glasses, but you should give them a call to make
sure. For completeness, I might as well mention their address and web
page:

3DTV Corporation
PO Box Q
San Rafael, CA 94913-4316
(415) 479-3316
http://www.stereospace.com/index.html

BTW I also have a pair of i-glasses and pretty much agree with all your
observations. The non-VGA resolution is not much of an issue for me,
however. While I did get the unit with the head-tracker, it was the
NTSC compatibility I was most interested in. I plan to do home
recording of 3D videos. I purchased the i-glasses first as my viewing
media. Next I have find some small color cameras with an external sync
connection. The last step is buying a multiplexer - which I will
probably buy from these folks. Not that any of this should be
considered an endorsement, of course. ;-)

Message-ID: <9509011124...@mail04.mail.aol.com>

Although I thought that my response to the Wirgin question was rather non
judgemental relative to other specific cameras and film and was only meant to
add some insight to the persons request for more information, I will clear up
some the points that Mr. Themelis asks. I use many cameras for three
reasons. One is the many different formats ( Realist, half frame,
beamsplitter, and twin full frame, Polaroid). There are sometimes when a
specific format is easier or better to use than another for me (obviously
others may not agree with this). The second is that I take both prints and
slides, and I load different cameras with different film types and speeds. I
do not like the results of shooting only slides and making prints from the
slides. I shoot slides for my personal twin full frame projection, and I
shoot prints with the Realist format cameras and the half frame format
cameras for the weddings that I do. The third is that I enjoy building my
own setups (twin rigs, Polaroid) or modifying an existing setup to do
something different. I get wrapped up sometimes in the mechanics and fun of
designing and building new equipment, not necessarily the taking of the
pictures. When I build something different I enjoy testing it out, and I
move onto my next project. Each variation on a camera or technique will
eventually have its' use, but not necessarily at that time. As for the
sharpness of the lenses, my opinion was relative to the cameras that I use,
including a 3.5 Realist, Nimslo, Kodak stereo, Loreo, beamsplitters. I was
trying to differentiate the lens quality from a subjective standpoint, as I
didn't give any testing numbers or even mention any camera comparisons. My
judgement means that one would not be dissapointed with the results produced
by the cameras' optics. That's all.
The flash synch speed of 1/50 allows more ambient light to expose the film, a
consideration of mine from doing weddings. Of course the camera will synch
at any of the speeds.
Yes, the Wirgin is my favorite camera not only because it was my first, but
it deserves to keep its' place among the good Realist format cameras,
including the Realist. If I started with a Loreo, it would not maintain its'
standing as my favorite camera for very long.

Subject: 3-D Depth
Message-ID: <1995090115...@garnet.berkeley.edu>

Hello everyone,

Why do 3-D photos appear to several levels of relief? I mean as opposed to
the more or less continuous depth of space we normally see. Is it due to
the limited amount depth clues available in photos?

Thanks,

Some of us (Elliott are you listening?) have similar experiences
while others proudly announce "I only take pictures".

At first I could not understand the question, but now I think you are
referring to something known as "cardboard" effect. Sometimes 3-d images
appear to consist of cardboard cutouts. The effect is more pronounced
when one uses long focal length lenses and longer separation.

I think the most important depth cue missing in the photos is "motion
parallax" a very powerful cue responsible for our sense of depth in motion
pictures.

Composition in a 3-d picture can be responsible for discontinuous depth.
One way to eliminate this is to use (as discussed earlier) a higher
perspective. By taking pictures from above eye level, the ground has a
continuous depth graduation and this creates a more pleasant 3-d image.

My first picture was of my wife a tree and a wall behind. I noticed the
same exacly effect. Here is my wife, here is the tree and here is the
wall. Nothing else. If I had composed the picture differently, the
depth changes would have been more gradual.

Subject: Stereo photography list & ftp site

There is a large (600 person) mailing list for stereo photographers
located on a machine at East Texas State University. Anyone who is
a stereo photographer or who is interested in stereo photography is
most welcome. We also have an anonymous ftp site for stereo. You
may wish to look in there at past digests to see if this stereo list
will interest you.

To subscribe, send mail to:
list...@bobcat.etsu.edu
And put in the body of the message:
subscribe photo-3d <your name>

After you've been added to the list, you'll get more information about
the list such as how to get a daily digest rather than immediate delivery
and how to unsubscribe from the list. (Both are done by sending commands
to list...@bobcat.etsu.edu.) So _please_ save that info message. 8-)

The address to post to is phot...@bobcat.etsu.edu but that address will
bounce your posts until you are actually on the subscriber list.

Here is some basic info on the list, a sort of charter:

The e-mail mailing list named "photo-3d" has been established for the
purposes of discussing 3D photography and closely allied subjects. In
this list, 3D is defined as the presentation of separate and different
images to the left and right eyes. This definition is not intended to
exclude lenticular presentations or the Pulfrich effect or "wallpaper"
stereograms. However, it is intended to exclude discussions of, for
instance, perspective drawing and "ray tracing" (often called 3D by people
in other fields) and is also intended to limit the discussion of
holography to headlines only, inasmuch as holography is a radically
different technique. Unfortunately, this is not the place to post 3D
computer images; many subscribers cannot afford to receive messages that
large. We have available a number of FAQs (Frequently Asked Questions) in
our ftp directory. Also in the ftp site are a number of stereo image
files. The ftp site is at bobcat.etsu.edu under pub/photo/photo-3d.

Discussions of the following (in no particular order) are encouraged.

Topics:
3D art
3D equipment and products, both commercial and home-brew
3D personal experiences
3D techniques
3D theory

Media:
3D photographic stills and movies
3D television
3D computer graphics
