[@derblaue]

@@starpeep5769 It's difficult because it's a unusual combination of the stereo angle and focal length. Once you have the images overlapping you must try to sharpen the image. This will naturaly decrease the stereo angle. You then have to focus on overlapping both images again. Repeat step 1 and so on. You will slowly sharpen the image while keeping your eyes corssed. After a few cyclesyou'll get to a tipping point where you'll keep the focus without effort.

[@vindi167]

[@jeffreygordon7194]

Neat. Do you mind describing what software/process you used in the early 90's to make them?

[@majorskepticism7836]

@@jeffreygordon7194 No software, I just lined the two images up with the right image on the left… When you crossed your eyes you’d see them correctly. At first I did it in-camera with a slide copier, photographing two slides in a double image, then printing it at a photo lab. I tried doing it myself on an enlarger, but I could only do black & white, and it was very clumsy. I got a computer and printer in the late 90’s but it was just as much work as in-camera, and printers weren’t too good then. I got a copy of “Stereogram” and saw a 3D painting by Salvador Dali that he never completed - inspired me to try hand-drawing stereo pairs, which I got pretty good at. A blood clot in my left retina left me with a small blind spot right in the center of view, so that endeavor ended. Back in the early 80’s I took 3D pictures on slides for a hand-held slide viewfinder (remember the ViewMaster?), or for projection with two slide projectors (or one double projector), a *silver* screen (has to be silver/metallic), and special polarized glasses (projectors need polarized filters on the lenses). There’s a guy who calls himself Dr. T 3D who sells lots of 3D related gear. Just google him. Now I just use red/cyan glasses to look at anaglyphs. Anaglyphs are not hard to make, even older Photoshop Elements has everything you need. Not as stunning as slides projected onto a screen (Watch Andy Warhol’s 3D Frankenstein), but, done right, anaglyphs work very well well. There are lots of anaglyph videos on KZbin and stills elsewhere. You will need the red/cyan glasses - shop around, they can be bought cheap of you look. I’ve bought them in packs of 50 for around $15. You only need one camera to start out. Just find a scene with no movement, put your weight on your left foot and shoot, then shift to the right foot for the second shot. There is no “right” distance - do several and choose the best looking pair. You will likely have to tilt one image to match the other, then shift left-right, up-down. For more accurate camera movement just get a focusing slide and mount the camera sideways. The images will align more easily than hand-held pairs. By the way, you can do “Giant Vision,” putting a 3D effect on distant scenery by moving many feet between your left and right images - a couple of feet to a hundred feet (best to have two cameras, two tripods, and an assistant). Or shoot out the window of a moving car, but make sure there is nothing close to the road like fences, mailboxes, tall grass, shrubs, hitch-hikers… I learned how to do these things using film. Wasted a lot of film. Expensive. Digital 3D is easier and lots cheaper. There are good videos on KZbin that explain how to combine a stereo pair into an anaglyph. Also, some show how to “fake” a stereo anaglyph from a single image - some of these are pretty impressive, but not true stereo. Good luck. Have fun.

[@louisrmusic]

The lenses in VR headsets are only for correcting the vision. Here the videos works the same as a VR headset, each side is for its corresponding eye, so you need to straighten your eyes by focusing a point further than the screen until both images line up. Same as the Nintendo 3DS, except the pixels are angled and it does this for you.

[@HarveyHirdHarmonics]

This is great! I've been using this technique since I was a child. I started by cross-eyeing repeated patterns and noticed some 3D effects when the pattern was slightly irregular. Then I drew simple 3D stereoscopic pictures on paper - just primitive line art, nothing special. Later on family vacations I used to take cross eye 3D photos of the landscapes. Just take a photo, step a bit to the side and take another photo. Didn't work well with moving water and other movements in the background of course, also make sure your shadow or reflection isn't visible. Other than that, the results were great. Don't know why I haven't been doing this anymore, especially today with smartphones where you don't have to worry as much whether the photos turn out good (back then you'd have to get the film developed and didn't know the result until then).

[@AlphaEnt2]

The crosseyed stuff is specially useful when you play the 7 differences game, where you have two pictures close to eachother. The different stuff gets highlighted. So i can no longer play that game, as i beat it in matter of seconds.

[@HarveyHirdHarmonics]

@@AlphaEnt2 Yes, I've been doing that too. In the German tv show "Wetten, dass..?" where contestants can bet on achieving difficult tasks, there was one who could quickly find the one wrong digit in two huge almost identical blocks of little numbers next to each other. I immediately knew how he did it and how easy it actually is.

[@Stratelier]

I remember doing stuff like this in MS Paint -- I'd create a simple tiled pattern then contour out a shape, copy & offset it just a little bit to create a 3D effect. I didn't get too much farther than that (you actually have to repeat the process across the width of the image -- something you can spot in the patterns of stereograms when you know what to look for -- without which, every irregularity in the pattern yields a positive shape in one eye and a negative shape in the other) but it was cool while it lasted.

With good eye control you can focus while cross-eyed

[@Stratelier]

The brain tends to adjust eye convergence and eye focus in tandem with each other, because that's what's most useful generally, and stereograms (cross-eyed or diverged both) require you to adjust them separately.

[@louisrmusic]

Yes you have to focus like if you were looking at something further than the screen. Each eye needs to focus one side of the screen, so the sight has to be near parallel. This isn’t even close to cross-eye. If you focus the screen you cross-eye already, and cross-eyeing even more won’t get you anywhere. On some websites you can read that the left image needs to go in the right eye and vice versa. You’d have to go cross-eyed so hard to do this, that’s completely silly 😂

[@luuk3656]

When my eyes finally focus it looks so cool

[@IAmElectrospecter]

There are two ways to do this, one by crossing your eyes and one by looking "beyond" the image (while keeping it in focus). I did it both ways and the second way looks a little nicer. You see the same illusions, they are just "inverted" from one another if that makes sense. Like if the image was a sphere, one method would make it look like its popping out at you and the other method makes it look like it's an indent

[@nofx7058]

if you are crossing your eyes you will be looking on the tip of your nose, so you need to look at the screen with peripheral vision? It is also very difficult to do this because the eyes in this position start to hurt very quickly, and no matter how much I look at the screen in this way, the two red circles do not connect into one. Should they kind of connect in the middle (in the center of the segment between the left and red circles) or should one of the circles (right or left) disappear? I don't understand

[@nofx7058]

and how do you look beyond the image, are you like looking directly at the screen (not out of the corner of your eye) and imagine that your monitor is transparent and you are looking through it? doesn't help, no matter how much I look

The way to handle it is to look at tip of your finger and than move it away. Your eyes' lines of sight would slowly separate from one another, which is, as mentioned above, exactly opposite of crossing them. So you need to separate them as far as posible, so each eye looks at the senter of corresponding side image. But, this technique forces your eyes to focus on the spot, which is nearer then the crossing of sights. May be itchy at first and cause myopia if you do it systematically

[@stormofdogz]

ive never understood these videos ever they dont work for me

[@KurisuKuri]

man this takes me back, i used to have a book back in elementary school that i did this with, it was wild as a kid

[@ladyrachel13]

It didn't work for me.

[@MG_Franklin_Kirby]

The circles never become one, but the video becomes three separate images, instead of two.

[@therealtaco7328]

I can’t do it. :(

[@LucindaPug]

I mean I’ve got a headache but that was really cool!!

[@zenfrodo]

For those who are having trouble, don't view it in fullscreen. For some reason, fullscreen made it much harder to get the right focus; when I reduced the size back to YT's default, it snapped into focus.

[@eccentricbass3730]

Usually these are hard to see, but this one was super easy, I got it immediately. Wow!

[@strainerr]

literally impossible to make it one

[@AnthonyVCL]

This felt surreal

[@jakeluke1814]

HELP IM SEEING THREE OF THEM

[@shwabb1]

same

[@zhpolarbear]

seeing three is right but you have to focus completely on the middle one, so when the letters appear you see them in 3D

[@midnightmosesuk]

Thanks, now I can't uncross my eyes and I have a migraine. You'll be hearing from my solicitors.

[@mooomoowitney5719]

It’s cool - however the two images are inverted.

[@hatto]

This is what I use to speedrun spot the difference games. The difference between the two photos will blink or rapidly appear/disappear due to the inconsistency of the two pictures. Literally takes less than 5 seconds to spot multiple differences.

[@eazy_eren]

how do you cross your eyes

[@astroroms]

omg this is probably the coolest thing i have ever experienced in my entire life? i could cross my eyes but i didn’t know u could focus it after?? ur v smart for figuring that out
