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
This is a great way to teach people how to do the Magic Eye puzzles. It’s the same method but was notably easier to do this than a Magic Eye.
This is actually the opposite method you’re supposed to use. If you cross your eyes to see a Magic Eye photo, the image will be inverted/inside out.
To view a Magic Eye, you’re supposed to look through the image. Personally I was never able to pull it off. These cross-eyed images are a lot easier.
Because of your comment I was finally able to do the magic eye!!! I can flip back and forth between them and invert the mountains. Thank you!!!
I’m glad it helped!
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:
Thank you, they look amazing
These are rad. Excellent post.
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!
Ooh, nice depth!
Thanks! It was a pain to set up the little screen trick but for what it’s worth, I won the contest!
Now I see it! There’s “depth” on the PDA screen too!
Yep. Anything worth doing is worth overdoing, I always say.
I remember my HP IPAQ, it was my first mobile computing device. That thing was so much fun.
I was mildly obsessed. It felt like the future! I miss technology like that. I’m kinda excited for all this AR stuff people are talking about because I haven’t really been excited by the latest and greatest shiny black rectangle in a long time.
Why do all of these look inverted to me? Like, what should be a mountain is a deep hole in the ground.
These are cross-view, your probably using the focus at infinity trick instead.
Wow, I had the same problem as the one you replied to and I thought you were making a joke I didn’t get but I stand corrected. You were absolutely 100% right.
Turns out I was focusing at infinity, didn’t even realize it was a different thing than crossing my eyes until I tried to cross my eyes first before focusing on the pictures…
Very cool, thanks.
Yup. That was exactly it. I was thinking “I know how to do these” and not even paying attention to the instructions at the bottom.
I’m cross eyed. Can’t get a third dot. Boooooooo
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.
No I didn’t. Thank you. I’ll check it out.
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.
Mountains are deep, land is puffy. Weirded out of that was ever the purpose.
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.
I love these so much thanks! On YouTube there’s also a ton in video format, like this one by Brian May.
Amazing! Thanks!
It’s a schooner!
You dumb bastard, it’s not a schooner it’s a sailboat.
A schooner IS a sail boat, STUPID HEAD
Isn’t magic eye something different? I thout it was !autostereograms@lemmy.world instead of cross view images.
You are correct, they are slightly different, but are based on the same effect of stereo imaging.
Awesome! I cross-posted this to !crossview@lemmy.world :)
Subbed! Thanks!
I don’t think the locations are all correct.
1st: Honolulu, Hawaii
2nd: Lake Palanskoye, Kamchatka Peninsula, Russian Federation
3rd: Wheeler Ridge, California
4th: Mount St. Helens, Washington State
5th: Mount Meru, Tanzania
6th: Salt Lake City, Utah
7th: Meseta de Somuncura, Patagonia, Argentina
8th: Wellington, New Zealand
Hmm, you are correct with the identifications, but the order I see in voyager is the one I’ve posted:
The only ones where I think we differ are 2 & 3. I’m pretty sure that the top one in my screenshot is wheeler ridge.
Oh, also, I really miss the old JMOL molecular models that you could view in cross- or wall-eyed stereo. Anyone know what software is required to make those?
I usually can do stereograms pretty well but for some reason I had to tilt my phone about 10° counter-clockwise for the stereo images to align to get the 3D effect.
Have you ever had your vision checked?
