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
Not sure why but those NEVER work for me lol
Not this, not magic eye books, absolutely nothing works.
Tried for many hours back in the day
I can only do parallel-view, not crosseyed, those look so surreal that way (inverted height/depth basically)
Works opposite for me. Cross-eyed versions look correct, and the parallel/wall versions have inverted depth.
Same thing with magic eye images, they're always inverted, like I'm looking into a mold of what the object is supposed to be.
