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

      Did you try the wall-eyed versions below? Those should be smaller on a mobile screen, and many people (myself included) find wall-eyed versions easier.

    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:

    These are easier for me than normal Magic Eye pictures, because I can just use the “floating hotdog”* method of putting it right up to my face, letting my eyes get used to being focused there and then slowly moving away from it until it pops out of the page/screen.

    *(to do the “floating hotdog” trick, put your index fingers end to end then put them right up in your eye line. Now slightly move your fingers apart until the floating hotdog appears)

      If you have astigmatism or greatly different lens prescriptions per eye, it may be very hard for it to work.

      If you do have astigmatism, you can kind of ‘squeeze’ or scrunch your eyelids down to compensate as you cross your eyes, and it may work better without glasses and closer up

      Some people it just never works with

        Is that why I’m seeing things that way? Don’t understand the difference really, but is really odd to see Mt St Helens as a sinkhole instead.

          Yupp, I never got the hang of cross-eyed viewing, even with the tips that are around, whereas the “looking through the image” technique is super easy for me, basically just relaxing my eyes. I assume there’s people where it is the other way around, and the cross-eyed method works better for them.

          Basically it’s about which image is transferred as information from which of your eyes, and the two different techniques swap the eyes, which also swaps the 3D depth information.

          I love the Wellington here viewed the “wrong” way - like the ocean is a massive plateau surrounding the coast, with that strip of developed area rising like another giant wall.

      Do you happen to have a dominant eye? If you primarily use one eye over the other I dont believe these work. For me, I have a scar in the middle of one eye that prevents most straight ahead vision, so its only used to add peripheral information.

      I tried so long I tried every method, never worked for me. Then eventually I found an image that made it work for me

      https://i.redd.it/25c330mmohu51.jpg

      (Sorry for the Reddit link). How I do it: put your phone screen right before your nose and unfocus your eyes. Then, don’t move your eyes, don’t move your focus, but slowly move the phone away from your face. At about 10-20cm distance, you should be able to see a squirrel with a nut in its hands.

      After that it became very easy to do other pictures simply by knowing what to expect (an actual 3d image).

      That being said the one above is really hard.

    These are all backwards. The eyes are reversed so everything that’s supposed to be a hole looks like a bump and vice-versa.

    EDIT : TIL about cross v wall eyed. I dont understand why they would do it this way though ? The image is much less stable, and moving it at all completely breaks the effect. Wall-eyed really allows you to move and observe details without breaking.

      For a lot of people cross eyed views are easier, they would probably give similar complaints for a wall eyed view. It depends a lot on how your eye muscles behave

      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.

        Focusing at a point behind the image is exactly what we’ve always done for every other magic eye poster because it only requires relaxing your eyes (staring off into the distance) for the image to pop into focus. Cross eyed viewing is damn near impossible on any screen at less than an arm’s length away without significant eye strain or external devices (like the stereoscopic viewers that photogrammetrists would use to view these kinds of images without inducing a migraine) and since the dot is on top holding a finger up as a guide ends up obstructing the entire view unless your arms are growing out of your forehead. The wall eyed view has none of these issues.

        I appreciate the post and your effort. But, the images themselves are frustrating and have killed my initial reaction, which was to share them further. Because I’m nearly the only person I know that wouldn’t loose interest in the explanation for “correct viewing” half way through. If they were wall eyed stereoscopic images, I could just say “Magic Eye”, they’d remember Mallrats, see the schooner, and go “Ooh neat.”

          Hmm, I mean, it works fine for me, but I’ve been viewing stereo images for 15 years, both wall- and cross-eyed, so YMMV. I’ll see if I can quickly edit together some wall-eyed versions of the images for y’all.

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

      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.

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

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

          Same here basically, cross-eyed viewing is super easy for me but I have to work for minutes to perform wall-eyed viewing. I was really excited to see a post with cross-eyed stereograms.

        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.

        Cross eyed is so much more uncomfortable. It also looks smaller than parallel to me.

      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).

        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!

          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?

            That wouldn’t be crossing. Crossing is when you focus your eyes in front of the image. Wall-eyed is where you unfocus your eyes behind the image. Trying to look at your nose is crossing. The way you look at most magic eye images is wall-eyed.

              I don’t think so. When I cross my eyes, it looks correct. Wall-eyed viewing makes it look like a hole. Crossing your eyes makes them go inward. Wall-eyed makes them go parallel. They’re created specifically for crossing eyes.

                You are correct. I know that I am crossing my eyes.

                Edit: Well, I filmed it. Apparently only one eye is crossing, which has the same effect of seeing the left image from the right eye etc. I admit I was wrong, but I can usually see these correctly. That one in particular isn’t working in my brain for whatever reason.

                  Yeah I found the poster’s advice worked well. I.e. hold your finger between your eyes and the image and start focussing on your finger and them drop it away as the dots approach. It made me realize I wasn’t normally crossing my eyes (for say, magic eye images), I was looking past the image and kind of uncrossing my eyes.

                  With these ones, they definitely work by crossing your eyes.
