stereoscopic images / videos with the naked eye!

Anyone ever tried to watch images or even videos in stereoscopic with the naked eye?

The idea is simple however it requires some bit of effort. You must interlace the two visions of both your eyes and focus the newly created image at the same time. In dutch this is called 'scheel kijken' (english word anyone?) and as far as i know not everyone is compatible with the technique, but i am convinced everyone can try.

I started the idea while reading the book "Egypt through the stereoscope" with some high-res images:

from:
online Ebook

It took me a couple of minutes to get the visions interlaced and after that it auto-focused when i rested my eyes upon the new vision. Once you got a locked you can even move around a bit or get closer, but the closer you get the harded it will be for your eyes to get a clear image.

After a while when you get used to it the image gets real sharp and images become easier to set.

I even got to watch the following movie in full 3-D :

Trippy movie

Did you ever tried it? And what do you think about it? I think it's incredibly trippy at the least...


edit.. sorry if this is the wrong topic, just couldnt find a better match

I learnt how to do this a while ago but i have only ever done it with a still image and i've gotta say, that video blew my mind! I ended up watching about 7 others as well and strangely enough to me i think it is as good as 3d tv- but just a little more interesting

Yep been there done that.

But thanks to you while watching that video I just discovered a very simple trick.

You know when you cross your eyes and focus on the image in the middle, the images on the sides are pretty distracting right?, so I simply put my hands near the front of my face to block out the distracting images and wow, it's like there was only one image in the first place but in 3D.

I think you need the glasses still. Crossing your eyes just makes 4 images. They're too far apart to condense into one image.

Cool stuff

After staring at the screen for 20mns like an imbecile I finally got it, ha.

Cross your eyes until you can see three images, basically combine two of the images together to create the 3D.

It might mean squint, but you don't squint to see these. You go cross eyed. Until the center most double vision images overlap, and viola! you have left and right images sent into your brain.

I love these. I used to do it with random sequences as a child, patterns on a wall, it would throw the background into confusion and make the wall appear closer than it was.

Then I learnt about stereographs and how to make one, but never really succeeded.

I still look at these... I've tinkered with 2 webcams to try and make my own, but the 2 cheap Chinese webcams were completely different in how they looked on the monitor.. meh, one day!

I'd love to buy a 3D camera to do this properly...

Those Egypt images are great, I used to have a whole load of stereographic images of Perth in WA from the 1800's and to actually see the roads where I am used to seeing vuildings and traffic lights, appear as dirt roads with old guys in hats with fuzzy moustaches in 3D was very cool..

Cheers!

You stop when you have 3 images, not 4 or you're going too far.



image one is image two is

      *                                   *

you co cross eyed until you have

*                         *                          *

this one is the 3D image^

if you see 4 images, you've gone too far...

damn white spaces lol

thank you i will update my post !

I feel the same way .. When i was about 10 years old i got this book full of noisy images and i could see images on 2 or sometimes 3 different levels.

As for the quality, it works fine for me too, with some effort i could watch a full SBS movie but i'm afraid my eyes won't get back to normal afterwards

Yea the egypt images are pretty cool. From what i understand from wikepedia, in the Netherlands a stereoscope was pretty common in a regular household around the 1850's and nowadays in musea's. Never got to play with one however..

lol... and now it's much easier to get a lock, right ?

More ways to ruin the vision and eyes Just the way the 3D televions are in question over the long term viewing of 3D programs.

Best way would be to attend the Macy's fireworks at NYC and watch it for real Priceless.

why would this be bad for the eyes? i can understand certain glasses are not good but this doesn't invlolve any unnatural process. please explain.

Try this one if you have dual screen:

Awesome!!

You can make one, similar to those kids toys from many years ago.. what were they called.. argh..

VIEWMASTER!! lol google saves the day. -- they were like funky binoculars that you had a rotating slide in, with two images in each frame. youd click the button and the next scene would appear.

I've not thought about them in almost 30 years. Maybes thats where I got into it. ha.. interesting.

en.wikipedia.org...

same idea, except the requirement to go cross eyed is removed and each eye gets the image in a normal fashion.

Why is everything a 2d ipod these days.. kids are missing out on fundamental things.. even wuth 3d tv's.. they don't get to see "Land of the lost" in 3d slide show format.. lol

Well I tried..unless I'm not understanding the method, It gave me a bad eye ache as I was trying to squint.

But definitely the prolonged use of 3D technology for home TV is in question right now.

If you're using a cross-eye technique, it helps a lot to swap the images so that they're on the opposite sides of a stereopticon pair. Otherwise, most people can't de-focus their eyes enough to look at a stereo pair that has any size to it.

Also, did you know that even with the right technique or glasses or whatever, about 30 percent of people can't see stereo 3-D images anyway? It has to do with your brain's ability to process what your eyes are seeing, and a lot of people have bad eyes, or bad brains, or whatever.

It took a couple of minutes, but that was COOL!!

Thanks for sharing.
