If you don’t focus on the x while you watch, it’s easy to see that the pictures are indeed the same.

I was having fun watching the picture slowly return the right pic to normal before it switched back.

what he ment is just watch the x in the center. after the one is blurry and the other is at full contrast, then when it changes and you are still looking at the x the one that was really blurry is better looking than the one on the other side, when in reality they are the same contrast.

It slightly resembles the cover of The Killing Sea. That book is just sad.

Are you cats trying to say this isn’t an illusion really that dense? Yes both images change at the same time via .gif but that’s not the point of the illusion. Several people have already explained what the illusion actually is so I wont waste my breath. The point is it does play with your eyes and if you follow the directions the images you end up seeing in your minds eye for a brief second aren’t really what is on your screen at the moment. Just figure it out.

i think it’s more of a gif thing, even if you don’t notice the difference between the contrast of two images, they change on their own

I only have a right eye. When I stare at the cross and the change takes places, the two pictures actually switch; the right one becomes a complete blur like the left one had been. As long as I stare at the cross they continue to switch.

the only reason we see this is because it takes a few seconds for our eyes to adjust to the change of light, just like when you are in the dark, and can’t see anything for a minute, your eyes adjust to the darkness. our eyes need time to adjust so that is why if you look at the x in the middle instead of each individual picture you will see what the “illusion” actually is

for a secondit actually looks as though when they become identical, the high contrast and blurred one swap places! What genious!

I would like to know if anyone that is saying this is not fake has tried the image outside of a web browser. It was pretty easy for me to download the image to my desktop, look at it in Windows Paint and retry getting the effect. Its not like I don’t see the “illusion” when its posted here its that I can’t get it to happen elsewhere. Let me know if the same process leads to a different result with different people or the same one as I had.
