My time has come!

The above stereographic image is for cross-eyed viewing (most stereograms are wall-eyed, so you may need to put your finger in front of your screen until this one comes into focus)

This is an image of Honolulu, Hawaii, published by NASA. Note Diamond Head (the volcanic crater) in the south.

Here are some other stereopairs published by JPL:


Wheeler Ridge, California


Mount Saint Helens


Salt Lake Valley, Utah


Wellington, New Zealand

    About 21 years ago (😩) I made a stereoscopic photo for some online contest. I was pretty proud of it.

    Edit: please ignore the fact that the light doesn’t match between the shots!

    Since some people are apparently rather salty about these being cross-eyed, despite the fact that that’s just how NASA made them, here, special for y’all, a selection:

      Haha sick, so cool. This is so much cooler than the old school stereograms with like a silhouet hiding in an image. How did you make these?

      Idk why I can’t do the cross-eyed, still wanna see if I can get that working as well

        These images were created by NASA, though you can make your own by taking two pictures about 4-5 inches apart. Try going to the Parallel View community to see more.

        Also, if you know what JMOL is (a molecule viewer), you can make it show you things in stereo by right-clicking, then clicking, iirc, “scheme”–>“stereographic” or “3D”–>“wall-eyed”

      Thanks. These are cross-eyed, not the originals. The originals viewed with crossed eyes all made holes out of the mountains.

        Allow me to word it differently: people are salty that the originals posted above are Cross-eyed, so these are wall-eyed (like I said in the image itself.

        The images in the top-level comment are distinctly not for cross-eyed viewing, since the originals were cross-eyed.

          When I view the originals cross-eyed, I see all the mountains as holes in the ground. I’m sure that’s not the intended effect. Try it!

            Define “Cross-eyed”. I get the impression that your definition is not the same as mine. Cross-eyed viewing is specifically shifting your eyes so that they would be focused on an object closer to you than your screen. Wall-eyed viewing is the term used for shifting your eyes so they would be focused on an object behind your screen. The originals above, as the text in the original NASA photos says, require you to cross your eyes. The images I have posted in this top-level comment require you to look through the screen at the wall. I don’t know what else to tell you. You’re just wrong. I’ve been doing this for fifteen years. The US Government has been doing it since the second world war. I think that, given that the current administration is made up entirely of cross-eyed imbeciles, we can probably take their word for it that something is cross-eyed?

            But, since just telling you to read the things I have already posted didn’t work last time, take a look at the difference between the CrossView and Parallel Viewing (wall-eyed) communities here on Lemmy. If you still don’t believe me, I cannot help you.

              I know the definitions. The cross-eyed method is way easier for me than the wall-eyed one. It’s not that I don’t want to believe you, friend. I’m just reporting what I saw. Did you check the picks yourself with both methods? I did.

                Yes, I made the second set. I have been looking at the originals since I found them months ago. Here, let’s do a test. jmol generated this image as “cross-eyed”. Do you agree?

                  This works perfectly for me with the cross-eyed approach, yes.

                  No disrespect meant when I asked if you tested your pictures. You know, it IS possible to swich the pictutes without testing, so it made sense to ask.

                  Thanks for being patient and troubleshooting my apparent viewing anomaly.

      I can still view these, but it’s much much harder for me.

      I don’t know why parallel isn’t the default.

        Lots of people can really easily go cross-eyed and look at these with no practice whatsoever. Fewer people can do the parallel kind with no practice or with the amount of practice they’ve already done.

      If you want wall-eyed viewing, you can just download the image and mirror flip swap it in an image editor. I also personally prefer wall-eyed viewing.

      This is exactly how JPL posted them, and they did cross-eyed viewing because the image jumps out of the page, rather than in (I presume).

      I can never get the parallel view to work. My eyes want to focus too quickly. :( cross view is so much easier to me. I wish they came in both all the time.

      You’re doing “wall eyed” viewing. These are for “cross-eyed” viewing. “Wall-eyed” means your eyes are focusing at a point behind the image. You need to cross your eyes for these. Try putting your finger in between your screen and your eyes, varying the distance until the dots merge. Then, remove your finger, focusing on the image itself. That should allow for cross-eyed viewing.

          Same - I’m super confused now. I don’t know what I can do anymore. I thought I just crossed my eyes until the images overlap but when I do that I’m seeing a hole too…so I guess not?

        Thanks that was it. I can lock in and focus the wall style very fast, as it is the most common. This took me while but got it with the finger trick!

    In feudal Japon, 19th century, a photographer made a lot of photos from the people in 3D to use in a viewer, hand colored.

    (Converted to gif, to see the 3D effect without eye acrobatics)

    Really can’t seem to understand how this works.

    Never did any “magic eyes” or whatever books as a kid, so maybe I just don’t have any practice in this, but whether I try to cross my eyes focusing beyond the screen, or “above” the screen, I can’t get the resulting middle image to look like anything other than a blur.

    Perhaps my eyes are somehow odd on the other hand. I don’t need glasses though, so I’m a bit skeptical that’s it.

    I tried all the guides I found in this thread, including the floating hot dogs, attempting varying distances both with the screen and the finger, then trying the wall-eyed variants too for all of them, none of them work for me.

    So odd. It seems it should work. No idea what I am doing wrong here.

    Or is this the joke? To get people to squint for minutes on end on their screen?

      I promise this isn’t a troll. In your case, it may be that your eyes are having difficulty focusing on nonexistent objects. If they’re blurry, it’s not that your eyes aren’t crossing, but rather that they are out-of-focus. Eyes naturally focus the lenses to bring near or distant objects into clarity, but when I was first doing magic eye images a long time ago, it also took me a while to convince my eyes that they needed to focus on the images.

      My guess is that, since the actual images are on the screen at distance A, but your eyes are crossing as if they’re looking at distance B, your eyes are auto-focusing for objects at B, but the images are still actually at A, so they appear out-of-focus.

      I used to be able to do them at will, and even overlap images an additional time to get a crazy second level of shape.

      But now I can’t, thanks to the american health insurance industry. yay!

      I was gonna tell you it was a meme and they don’t actually work. This being in science meme I thought they might actually be stereographic images, but it’s from so far away you wouldn’t be able to discern any 3D-ness. But I was wrong the height is exaggerated. For me the walleyed version worked for me, I just had to zoom in on one image and hold my phone quite far away.

    Well, its the first time that i manage to see one of these magic eye images… but I need to ask. Most of this seem to be inverted (i see mountains as sinks, lakes and rivers are higher than peaks). Is this intended? I’m interpretint it wrong?

      These ones require crossing your eyes, whereas the other type you relax them (like looking further away).

      I find the other type way easier and struggle with cross eye ones. For these images you could swap the left and right portions to get it working the other way.

          Yes, I saw them afterwards. Nice work! I can do the cross eyed ones with some effort but the wall eyed ones (I didn’t know the name before) I could see instantly and with far better focus.
