| I met a fellow shooting with 2 SLRs fused to make 3D photographs. We talked for a bit and he told me to check out his club's work at this link if you can take the eye strain the cross eyed shots are pretty amazing. |

| I don't get the difference between parallel viewing and cross-eyed viewing, other than the size of the image. Am I missing something? |

| actually, that is very cool. Didn't know you could view 3D without glasses. |

Ok, had lazy eye as an infant, surgery on both eyes...can't view this....what does it look like? I can't see the difference. :(
(That might explain why my shots look blurry, lol.) |

I think the upper ones are designed for a stereopticon, and the lower big one is sized to get the same effect by crossing your eyes.

If you can cross your eyes enough, you get the two images to overlap and you get a pretty decent 3D effect. It helped for me to view them about 18" from the screen.

Looking at then larger images,when you cross your eyes you'll see 3 images. As you adjust the crossing of your eyes, the middle image will line up with both images and will appear to be 3D.
The experience is not unlike those magic 3D posters at the mall that you had to look at just right to see a hidden image. |

| It really works ! I would have lost a bet for sure ! |

Yeah, I'll need to use one of those -- can't get the big ones to work. I'm disappointed there isn't more info about the club, since it looks like it may be local to me ... :-( |

It actually works really well. I find that I can do it in two stages. First is to get the two images to line up, and then once they are lined up I can bring them into focus.
It worked particularly well for the bridge shot, I could see it perfectly in 3D! |

Practice helps a ton on these. The more you do it, the easier it becomes. I've done so much of it, I can snap it into view in a second or so.
FWIW, this technique does 3D the "real" way, that is, it works by replicating the way our own 3D vision works, by processing two views from slightly differing viewpoints. The difference is that you can choose how far apart your eyes are (the distance between the two viewpoints). The farther apart the viewpoints, the more dramatic the 3D effect.
For landscapes where all objects are relatively distant, it's even possible to generate an image pair out of two consecutive shots from a moving vehicle. This stereogram:
Was created from two consecutive images shot from the window of a commercial jet on approach to Denver.
ETA: The viewpoints on the above image are about 200 feet apart, based on the frame-to-frame timing and the estimated aircraft speed.

Can't do those either, lol. Oh well. |

| My eyes will go bonkers before I see anything in 3d. Ever since I was a kid I could never see these in 3D. I must not be normal, or is it the other way around? :) |

Can you cross your eyes? If you can, then you are capable of making it work. The first trick is controlling the amount of eye-crossing to overlay the two images. The second part of the trick is, once the images are overlaid, focus on them. Your eyes will want to focus closer, but if you concentrate on the overlaid images, they should snap into focus. |

It looks like it's the Oakland Camera Club |

 I did some of these after getting information from another thread a few months ago. They are surprisingly easy and don't require mathematical precision. Your eyes do the work. (My daughter can't go cross-eyed, and can't see these as 3D)

I loooooooooove looking at those!
If you have a hard time with it, don't give up. Once you see them for the first time or two, it gets much easier. I can "get" them almost instantly these days, and the effort is SO worth it.
At least the GOOD examples of that technique are so fun to look at, the effect can be downright startling.
This one was my first ever effort. I keep dreaming of getting a gizmo for my tripod to make it a bit more precise to get them right.

| I like the bar you put between the images Karin, it makes lining up the two images much easier so the single bar become a frame. |
