I shot some stereograms recently (OK, 6 months ago) on Velvia and only recently got around to developing, scanning and combining them. They look fantastic on a 3D TV of course but if you're capable of going a bit crosseye while maintaining focus, you can see some of them here: Stereograms (http://www.flickr.com/photos/24125157@N00/sets/72157636957426835/).

These aren't posted in the gallery because the resolution restrictions are too low. PM me with your email if you have a 3D TV and want a couple of MPO files to try out on it.

Feel free to make this into a "post your stereograms" thread...

Very nice.
Did you ever find decent optics for that stereo viewer you wanted to build?

Thanks. I haven't bothered to do it yet and will probably just get one of the pre-built ones from that Berezin website.

Which camera did you use? I have an Realist,and it's a great camera. I also have a TDC projector but haven't dug it out in dog's age,and will probably go to digital for projection

Thats very cool, i remember looking civil war stereograms and thinking it was the neatest thing I have ever seen.

Great work. Keep it up.

Quite nice. More people should do this, I think; there are stereo cameras out there at reasonable prices, mostly scale-focus with triplet lenses, and they really aren't hard to use. Mine is a Wirgin Stereo, basically a stretched version of the Edixa. Images at http://www.flickr.com/photos/ntenny/tags/stereo/, unfortunately all hybrid products as I don't have an enlarger.

I have a Sputnik, and it's probably my favourite camera.

Did you have to do any work on it for light leaks and so on? I've always been tempted by them, but I've been held back in part by reading that they have classically Soviet quality control.

I took it entirely to bits and cleaned everything before I used it, lined it with flocked paper so that the shiny insides were no longer shiny, fitted some light trap material around the doors, and replaced the gears on the front with the equivalent parts off a pair of slightly newer Lubitels so that I had a filter thread I could screw a lens hood into.

All of these things (apart from taking it to bits; the self-timer was a bit sticky so I thought I might as well) are necessary but none are difficult. I think it cost about $130 altogether, including the parts donor cameras, so it was far cheaper than the modern Chinese stereo camera that was (is?) available a couple of years ago.

I find this fascinating. I'm installing a home theater this weekend including a 3D projector. If I can shoot 3D stills and project onto my 10' wide screen to view with the projector's active shutter glasses, I think that could be amazingly cool and fun.

Any other suggestions for cameras and such? I don't know the first thing about what stereo cameras were made and what features they had.

I used an RZ67 actually, with a macro rail installed sideways to give me the lateral offset for each frame. You only need a "real" 3D camera if you want to shoot 3D images of moving things.

Roger: absolutely you should try it. It looks awesome despite the low resolution (1920x1080) on most home projectors and TVs. Showing images at high quality I think is the main reason I'd consider buying a 4k TV because for sure there is no broadcast content out there to give them any other purpose.

Shoot, Roger, just go out with a sliding camera mount and shoot two frames with the camera you have. That way you can use your existing lenses, the resulting pair of slides can be thought as "in-camera dupes" as Galen Rowell used to call them.

They can be 2-D or 3-D as the occasion calls for it.

For example, any of Polyglot's stereograms, would stand alone well as a 2-D photograph because of the rich imagery...

It's just icing on the cake that there's a stereo pair in there!

Very cool. I thought of some kind of movable bracket or such, but I would like to be able to shoot photos including people in at least "normal" motion, for some of what I have in mind.

I was definitely doing a projector not a TV though and 4k projectors are still absurdly expensive with the least expensive coming in at $14k street. The TVs are coming down drasatically but, as you say, there is a lack of content though I've heard that 1080p content upconverted still looks amazingly better than regular 1080p. I compared 4k and 1080p flat screens at the local Fry's and while the 4k was incredibly good they just had some looped video for content AND I'd say the jump isn't as big as standard def up to 1080p.

I went to that site you mentioned, Berezin, and found mixed info. All the references to 3d display on TVs is to, well, TVs and particularly Samsung. There are mentions of other displays but not a lot of clear easy to find info and they particularly list Samsung and Mitsubishi, DLP for both and LED for Samsung. My new projector is an Epson Home Cinema 2030, which is a three chip LED projector. Will they all display the same files as far as you know?

Some kind of bracket like that would certainly be a way to get started without buying more hardware.

You can just do the "astronaut shuffle" and just shift side to side. It works better than you'd think. They did it on the moon.

Does someone make a bracket or the slide rail PG mentioned to make this easy? I'd be concerned with getting the lens rotated - that is, you want to slide it, say, three inches left or right but would have to be careful the camera didn't also rotate.

Search for "macro rail" on eBay. The first few results are all 2-axis black rack+pinion things with ruler markings, about $30-$35, and I used one axis of one of those. No rotation, just a clean translation.

And of course with the ruler on there, you can do hyper/hypo-stereo (it changes the appearance of scale) by choosing your interpupillary distance.

I finally finished the theater installation Saturday, and got around to viewing the stereograms William sent me just now. They look great, absolutely amazing projected to (on my screen) several feet by several feet. My screen is actually about 11' wide but that's for 16:9 video. These shots are much more rectangular but they fill the screen vertically.

I'm hooked. Got to buy that macro rail, but I also notice the moved people in a couple of shots and I think I'll really want a stereo camera too. But I can start with the rail as that is cheap and easy.

viewing them works well doing the cross- eyed stare
a 3rd image pops up and is 3d.
