• David (or is it Bruce), thank you for your opinion. I myself, and the vast majority of people I have shown in person, and who have visited this page, and the thousands of others using the crossed eye method report seeing the 3D effect correctly with this method.

    When I view these images with the parallel eye technique, the 3D effect is clearly reversed. When I swap the images and view parallel the 3D is correct. I, and many others, find the crossed-eye technique easier and more comfortable, and the images are displayed here in the correct configuration for that technique.

    I have a really hard time keeping my eyes crossed. Sometimes It just hurts to hold it there.

    For people who cannot do this, there is a very simple way: get up as close to the picture as you can without losing focus on it. Now measure the distance between the picture and your forehead. Take a piece of stiff card and cut it so that one pair of opposite sides equals this measurement and the other two area about eight inches. Hold this card between the two stereo pics and place your forehead lightly against the card. Look straight ahead. It’s as simple as that!

      Yes, the cardboard trick between the eyes is very simple and effective. Thanks a lot. Much easier on my eyes too!

      This only works for the parallel method, not the cross-eyed method. So if you use this method for these images, the 3D effect will be reversed.

    after trying the cross eye and getting it the second time, i got too excited ad started clicking pictures in 3D… but a lot of people I know found it difficult to use the cross eye.. So I developed a technique which is very simple… here are the steps…

    Step 1:
    Get a cardboard or a sheet of A4 paper or a chart paper. It would be better if it is dark in color but even white paper would work. The size should be somewhere around A4

    Step 2:
    Cut a square hole in the middle of size 1″x1″

    Step 3:
    Sit in front of your computer screen at a distance of around 1.5 to 2 feet.

    Step 4:
    Place the sheet between your face and the screen [around 1/2 to 3/4 feet away from your face] such that your right eye can only view the image on the left side, and the right eye can only see the image on the left. [see attached image to get the idea.] you can move the sheet forward or backward a bit to adjust.

    Step 5:
    Close you right eye and see that your left eye can only see the image on the right and then focus on the image.

    Step 6:
    Close you left eye and see that your right eye can only see the image on the left and then focus on the image.

    Step 7;
    Start blinking repeatedly (not very fast) while you try to focus on the image in the middle of the hole. pull the sheet around 2-4 cm towards yourself while to look at the center and try focussing on the center of the image/video. stop blinking and see if you can see the 3d image. IF not, repeat from step 5.

    The blinking causes the eyes to auto focus the nearest object… just like the handycams/digicams autofocus functions, but you need to have your eyes relaxed.


    hope this helps

    Here’s an easy to understand fully animated anime tutorial by some cute anime characters i made;

    (It also includes bonus maths to calculate your optimal 3D viewing distance and how to create simple 3d glasses).

    I hope it helps!

    I got it but I think my eyes are messed up now. Gonna go rest. My eyes almost got stuck in the 3D dimension

    FINALLY!!! It took me about 40 minutes to get it but I did! I couldn’t do it without the pencil in front of my face but since I was only looking at the pencil lead, it didn’t matter much. I found out that looking at the black border around the middle picture really helped with the focus and relaxing part. Hope that helps others

    i find it much easier if i put my hands like this: like when you mime a gun, then put them close, cross the fingers after the second, couple the thumbs and put the index fingers at about 3-4 centimeters (1.5 inch) – this is for viewing images on standard size Flickr – so that if you close your eyes one by one you see one time one picture in the space, the other time the other picture. my problem is still focus, btw.
    i can’t twirl my tongue: it’s a gene.

    holy (#&) how do u make the picture like that they r exactly the same right but like how do u edit them

    Once you get the focusing down, you can make it happen quick for nay of the examples. Pretty slick – it makes perfect sense, but I would have never thought of it. How well does it work with large prints – say 2 20x30s side by side on a wall? I think I will be testing that out!

    Can’t do it.
    If I look at it cross eyed I just see three images instead of two, but no 3D.

    Yeah, I got a lot of practice in the “crossed-eye” technique 25 years ago. Chemists were printing up a lot of molecular structures in chemical journals with pairs of photos, to help visualize the exact 3-D structure. It’s second-nature for me to do so now. Of course, you must keep your head level, not tilted, and make the features on each of the pair of photos match up.

  • Pierre Savoie

    By the way, anyone can make their own photos like this. Get a camera with a tripod. Sight the photo subject the way you want to take it, but then move the camera to the left 2.5 cm for every meter away the subject is. Then take another picture of the same subject 2.5 cm to the RIGHT of the central position instead. Print the pictures and put the left-position picture on the right side, and the right-position picture on the left. Crossing your eyes will give each eye a different view, the pictures merge and appears 3-D.

    how do you convert them to 3d? with photo shop or somthing? please email me the instructions at

    Are there any side effects to viewing cross eye 3d?

    Reply FIRST……………………..

  • No mention is made that some people cannot see crosseyed. If you are a parallel viewer this site is not for you. You may see a stereo effect but the layers will be inverse depth.

    Hi Neil, nice article. I do know so called “stereographic” 3D images, where in the jibberish of various shapes is hidden 3D picture. Some news papers where publishing it regularly as competition in “fun” section, and you needed to guess what’s hidden there. And I even created small programs to render such images during programming classes, but it never occur to me that same effect could be achieved by camera ;)
    I do have small hint for you about the technique to learn how to see “3D”. I had problems to learn it using the same steps you describe and then I found out “my way”, maybe it could help others:
    – sit in front of monitor as described infirst step.
    – then lean forward and slightly touch the screen with your nose.
    – do not focus your eyes on screen, but do relax them so you will see strongly blurred picture (we call it “looking to dumb” ;))
    – start to lean backward and keep your eyes out of focus
    – at some distance you will start to see the 3D image
    – what helps if you have problems: try different picture with something really simple (too complex shape/too many colors are harder); try different distances from screen (depends on how good you can cross eye); train with smartphone (much easier to move in/out of screen)
    …in any case everyone will look dumb learning this “view” :D
    cheers & thx again, Pavol

    what’s missing from the cross-eyed viewing technique is blinkers to block the unwanted image from each eye. Try this: close your left eye, now place your hand(or other object ideally with straight vertical edge) beside your right eye and gradually move it across until you can only see one image(on the left of screen). Now do the same for the other eye: close your right eye and cover the left half of your left eye so as to block the image on the left of the screen. Now open both eyes and you should see one image clearly. So I am suggesting using blinkers, in stage lighting they call them “barn doors”. Or try a pair of clear or lensless glasses with the outside half of each leans frame covered with dark tape or painted, like half an eye patch.

  • It worked but it looks like the picture behind the screen it doesn’t pop out
