Here’s a relatively new optical illusion, examples of which were featured on multiple occasions. I think today’s version beats them all! In short, it makes your brain/eyes play a trick on you, making you “feel” that the photo on the right is slightly slanted. In reality it’s not. How can it be that the both photos are exactly the same? Anyone understands what makes this effect work? I have no idea, I tell you, no idea!

Illusion of Two Tracks

    The two pictures are exactly same….I cut the 2 pic on photoshop and pasted the picture on first pic…and then set the second picture as Overlayed…Its matches…

    Steroscopics picts… period.

    a big lol for all the “scientifics” explanations…

  3. Lasse says:

    Well they’re really not the same size, try to copy both – Left pic is 292×220 while the right one is 294×220…

    the snwy part on the right pic looks like the wite background, so you dont notice it

    it looks like an illusion because the straigthness of the sidewalk on the left throws off your focus to the correct and same angle of the two photos making the angle look sharper, it is merely a trick of the eye.

    I held up two straight edges, one to the left track in the left pic and one to the right track in the left pic; they are not parallel. But the left track in the left pic is parallel to the left track in the right pic and the right track in the left pic is parallel to the right track in the right pic.

    But there is a difference between the two pics though it is very subtle. If you measure the distance from the left edge of the left pic to the left hand grass line you will find it is a bit less than the measured distance from the left edge of the right pic to the left edge of the grass line. The two pics were taken from two very distinct viewpoints.

    just look at the right down cornet…..it’s make a different causes an angle….right?

    It is because you brain thinks it is one picture with the middle between the two pictures, not two same pictures.

    It’s simply because the straight edge of the right photo is right beside the angled line of the grass in the left photo. The photos are identical, but because the lines in the images aren’t parallel, it throws you off when looking at the adjacent lines of the grass on the inner sides of the photos..

    It looks slanted because the straight edge on the right picture, is next to the diagnol edge on the left picture, therefore it makes your mind think that the picture is actually tilted. because is this was reposted, with one on top of the other, rather than next to it, they would look EXACTLY the same :) hope this explains it…

  11. Since both the images are same, our brain is looking at them from a single perspective. Since the left most edge of the left image serves as the fist angle running towards its infinity(note: in our mind the vanishing point is supposed to be same for both the images since both are being looked from the same perspective) the middle edge of the image(which actually is the first edge of the right image but is still serving as continuation of the same perspective) seems to be suddenly diverted away to a new vanishing point and so appears to be rotated clockwise.

    At first looking, the pic on the left (to me) looks slanted. I am however myopic haha Dunno if that makes any difference

    These can be viewed as a stereoscopic image. Just like the “Magic Eye” Pictures” If you unfocus you eyes and allow them to cross you can see a third middle image in 3D

Speak Your Mind

You can add some images too.
