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:

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

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

Mountains are deep, land is puffy. Weirded out of that was ever the purpose.

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.

Ahhhh this doesn't work on phones? I also did Wall eyed, works quite easy but the cross eyed hurts lol.

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.

Yeah my eyes are prolly not used to crossing or something. When trying the finger thing to cross and merge the dots in the middle, it does works but it hurts to much to keep it stable. Will give it a shot on my PC later. I did toy a lot with wall-eyed ones years ago, so I intuitively started doing that until I noticed a lake on top of a hill in the third one :')

Yes it does work on phones, but it also works on computers. Stop being a peasant and buy a computer.

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."

LOL. Cross-eyed viewing is extremely easy and is very easy to do on both a laptop or desktop display as well as a phone. It takes no strain nor do I need any "devices."

These images are easy to see and take no effort. It seems like the issue is with you.
