This is great! When I look at each picture with one eye simultaneously, I see the image in 3d.

Pro tip: this is also how you can quickly solve those "whats different between these images" puzzles.

I wonder how widespread this understanding is.

I figured it out a few years ago, but haven't heard anyone else mention it. It's a really cool hack.

I sometimes do, but usually it is more fun doing it the trafitional way with the kids!

I’ve used this technique since I was a kid, and have always been fascinated with how my eyes perceive both a 3d image and simultaneously two separate images overlaid.

It’s something I think about many times per day - I mean, I’m looking at stuff all day, and this is such a fundamental aspect of the experience of looking at something. But my impression is that most people are only barely aware of how this works?

Observing the observation.

Something zen about it...

Don't think but it just is.

I have only told two people this trick. You have now told considerably more. I am truly hurt.

You can do this with text too (like in spreadsheets, code, etc) to find differences visually.

Same! It’s truly amazing that our brains are capable of instantaneously synthesizing those minute differences into three-dimensional information.

Just tried the same, and I have only one word: stunning!

You can also cross your eyes such that each image overlaps each other to get a persistent 3D representation

The depth is inverted if you look at them cross-eyed. If you swap the positions of the two pictures it will look correct.

Alternatively you can look at them by relaxing the eyes to infinity (parallel lines), which I find much less painful than going cross-eye.

I could hold of for a few seconds, but my eyes kept rejecting the image. It's like they somehow knew that they were more than the usual spacing apart (if that matters, for stereoscopic images?)

Try moving closer to or farther from the screen.

My eyes did this too up close, but could focus once I backed up.

How far back?

Mine gets better at arm's length on my phone, but my visual focal distances are funky because I have 3 dipoters of difference between my corrective lenses. All I can suggest is "try moving back and forth and see what works."

nope it doesn't matter. It is known to cause motion sickness in VR, but as for viewing photos, any amount of separation works as long as the subject and details have a relatively narrow angle opposing each other all the way from the bottom to the top. The very close waves for example are probably simply too far apart compared to the waves in the background, but everything else is great in this set of photos.

i just want to say thanks for pointing this out.

New found possible love, stereoscopic photography. Honestly the stereoscopic effect is absolutely beautiful, even more so that each individual photo

You'll love it. There's dozens of us. Reach out if you want to learn a bit more!

I assume the two shots need to be taken from slightly different angles to properly work, right?

Yep pretty much. Then you just need a way of showing them back to the correct eye.

I sure do- I have tried the stereoscopic effect before but it seems impossible to do.

I keep seeing both images rather than a single synthezised 3D image.

You can use a device to display the image. Things you can use include a Vr headset, a 3ds, or some rig with a lens https://www.andybaird.com/travels/skylarking/3d/viewer.htm

Probably the dead simplest thing to do is find a thrift store vr headset designed to go over a phone and get a 3d image viewer app.

How do I do this? I tried but I don't have individual control of my eyes, so I'm not sure what to do.

I also can't control my eyes directly, but I can implicitly control them somewhat by deciding what to look at.

For parallel viewing, try focusing your eyes on some object in the distance while still focusing your brain, not your eyes, on the image in front of you. It can take some hours of trying if it is your first time.

I find cross-eyed viewing much easier. For cross-eyed viewing, try to focus your eyes on your nose, and then slowly try to focus your brain on the image in front of you, just like when trying look at something in the corner of your eye without side-eying. At the start, this might mean that you see two versions of the image far apart from each other. While focusing your brain on those images, try slowly focusing your eyes a bit more in front of your nose until the images perfectly overlap.

The depth and detail that you experience when viewing these images stereoscopically is incredible… and then to consider that the shutters were not synchronised, that this was a complete fluke is just wild.

Thank you for pointing this out !

Indeed... I had to practice my old stereogram eye control, but it worked!

And the author's name, for me, read as Eron Grisman

Some say… you can measure his position or his speed, but not simultaneously.

Seriously, how do you do that?

I seem to be unable to see in 3D.
