Description
Yo.This thingy is called a stereogram. While inconspicuous at first glance, it withholds a great power, for when watched properly it reveals a hidden picture. Pretty cool right? WRONG!
Okay no it is pretty cool, however it gets EVEN COOLER, for not only it can show a hidden picture, but a 3D hidden picture, meaning different parts of it can be perceived at different depths.
"BUT HOW? HOW CAN I BE BLESSED BY SUCH A SIGHT???" I'm sure you're passionately asking, well this post's purpose is precisely to explain that.
------------------------------------------------------------------
The what
You might have noticed that the stereogram is made by a "stripe" of pixel repeated over and over (well, almost). What you need to do to see the hidden image is move your eyes so that 2 of the repeating stripes (two adjacent to each other) overlap.
What I mean by "moving" your eyes is they need to do this:
Top view:
What your eyes would normally do:
----------- < computer screen
/\
/ \ < your eyes' line of sight
. O O < your eyes
What you need to force your eyes to do:
----------- < computer screen
| |
| | < your eyes' line of sight
. O O < your eyes
The how
Here comes the hard part. There are different ways to reach that state, the way I personally learnt how to do it was to watch my screen while focusing on something behind the screen.
Here's anotherapproach:
1. Start by putting your face up close to the printed stereogram or the digital screen with which you’re viewing it. Hold it horizontally and look through the image as if it weren't right in front of you.
2. Then move the stereogram slowly away from your eyes. This is the point at which your eyes will try to do what they do naturally – readjust focus. Do not let them. Continue to look through the image as you move it away from you. It may take a couple of tries to get this to work.
3. When you’re confident that your eyes can continue to look through the stereogram, move the image back and forth until the patterns begin to overlap. You should be able to see the beginnings of a blurry three-dimensional picture.
4. Give your eyes a little while to adjust. Once the image snaps into place, you should be able to see a sharp three-dimensional picture.
Extract from www.skoda-storyboard.com/en/sk…
Your goal is to make it so that the two white dots on the top overlap, so that you see one white dot in the middle, with 1 white dot on each side, 3 in total.
If you're successful, in the image above you should see a square on the left and a bigger circle hiding its upper right corner.
It is important that you see the circle as IN FRONT of the square and both the shapes as IN FRONT of the background.
If the shapes look to be further away than the background, you're doing it wrong and you won't see the intended effect.
If that's the case here's what you're doing wrong: instead of "distancing" the lines of sight of your eyes, your crossing them more. In characters,instead of going from /\ to | |, you're going from /\ to X.
That is a different kind of stereo-vision, one that I don't intend to explore at the moment.
That should be it!
If you have trouble managing to accomplish this troubling but at the same time definitely imperative task, feel free to contact me and I'll try to help you see the truth that up until now has been kept away from you.
Have a stupendous day
