If anyone found this more difficult than usual it's because these images are accidentally transposed so that the things close to the camera seem far away! Here's the corrected image:

Nice shot Kirbic - once you lock in it's very deep and you can 'look' into the distance as you really would.

Jon,
You must be a "wall-eyed" viewer... the images were transposed so they will view correctly with the (usually easier) cross-eye technique. I forgot to put that note in my post, thanks to all for the discussion of the difference!
BTW the two perspectives for the mountain image were achieved by taking two photos in rapid succession from a moving aircraft. They were taken approx. 1 second apart. During this time the aircraft moves over 500 ft!
Daniel, thanks for the Stereoscopy.com link, I was unaware of that site... uh-oh, another time sink discovered.

This is my first stereograph made with the sony F717.

My very messy computer area. Boring photo, but I was just testing the technique.

| I have seen some 3D images like these before, but in a box with two eye holes, guess it must just be doing the same thing but eliminating the whole cross eyed part. |

I can only see the wall eyed versions. So the best thing to do would be making 2 versions.
I have seen animated gifs made of the 2 photo's needed for a stereograph, by showing them very fast you get some sort of 3d effect. |

This worked pretty well, but the thing I found most interesting was the mirror. In each individual picture the mirror is reflecting something pretty indistinguishable, but upon looking at them in 3d mode, suddenly it became very clear what was in the reflection.

| This is too cool, I have an Olympus c5050 that will allow you to do split or 2 in 1 pictures. I tried it on my table with minimal set up and it worked!! Got an OK result after only 9 pictures taken. I have wanted to do this for a long time, thanks. When I figure out how to post, I will let you see my sexy pig! |

An interesting side note: I'm near-sighted, so things that are farther away go blurry for me. Sitting at this distance I can make out images on my computer perfectly clearly, but when I tried viewing a stereograph, the result was blurry until I put on my glasses. I hadn't expected that.

Thats right G, the Optio S can do in cam 3d pics, it also comes with a special 3d viewer. Still havent tried it out though. :(

I used to work with aerial images that worked much the same way. It was basically 2 cameras each taking a 10"x10" image, half of which overlapped the frame from the other camera. The cameras were much farther apart than human eyes, and that greatly exaggerated the stereoscopic effect. Objects on the ground and the terrain would really pop out.

NASA is posting some nice photos from the Mars lander 'Spirit'. Some of them are in stereo - there is a left and right version of the photo. By putting both photos side-by-side you can get a 3d view of Mars, either by free viewing as described in this thread, or with a vintage stereoscope.

Very cool indeeed... I didn't realize there were left/right stereo pairs posted!

Very cool!! Would you mind explaining a little more on what you mean by further apart? Do you mean moving your camera horizontily left or right or swivelling your camera. |
The camera should move left/right from its original position just a few inches, while maintaining its orientation otherwise. You are trying to simulate capturing one image through each of your eyes.
There is a tripod attachment I've seen for doing this -- it attaches tot he tripod and the camera attaches to a secondary mount on a sliding track. |

Improving on the binocular separation just a bit, NASA now has a pair of satellites in stable orbits -- I think in the Earth's Trojan points -- taking stereo anaglyphs of the sun. If you don't have any 3-D glasses, one of the links eventually leads to instructions for making your own. Also, here's the NASA tutorial for making 3-D images (targeted for Grades 6-12). |
