These two photos are the same, but your brain might not agree

A new photograph is making its way around the internet, bringing to mind the famous “dress” and wall cigar optical illusions. In this case, there are two pictures of the same road, but while one of them looks to have been taken from a different angle or height, they’re both exactly the same.

The photographs have been shared on Imgur and Reddit, where the majority of users admit their brains are telling them they're two different images. “For me it looks like the roads are going in different directions, like one road forking off. It’s hard to believe the two streets are actually parallel,” wrote redditor jerrydisco.

Another Reddit user, Shroffinator, helped prove the two photos are the same by labelling each one and layering them on top of each other.

So, why is it so many people see different images? The optical illusion comes from the way the two roads appear to converge at the bottom of the photos. The brain interprets this as one single image containing two paths coming together, which is why the two pictures don’t appear perfectly parallel.

A similar effect is found in the famous ‘café wall’ trick, which can create an illusion where the rows of horizontal lines taper at one end.

For anyone who didn’t use the internet back in 2015, a photograph of a dress went viral as people argued over whether it was gold and white or black and blue. The color was eventually confirmed to be the latter.

Another optical illusion that still fools many people is the image below. While it initially looks like a wall with large gaps between the bricks, there’s actually is a cigar sticking out of it. Once you see realize the object is there, it’s almost impossible not to see the cigar.

Um no, no it isn't.. I dropped the image in InDesign, made line going with the bricks on the left street, copied and pasted it exactly on to itself, then moved it directly right with the arrow keys..

The two images of the street in the first photo are exactly the same. The reason your line don't line up is because you put them in different spots in the two image. If you still don't believe it, try this. Delete the image on one side and then take the image you kept and copy it next to itself. You'll get the exact same effect you see now since both images are EXACTLY the same.

The angled line is in exactly the same position on the Y axis (height-wise).. I did use the image at the top. I'll try the same thing with just the left image.

This time I used only the left image, cropped out the right, positioned them side by side, did the same thing, and now they line up, yes.

They aren't the same in the image at the top of this article.

This article looks more like something that should be in Phycology Today rather than Techspot ......
phy·col·o·gy
fīˈkäləjē/
noun
noun: phycology
  1. the branch of botany concerned with seaweeds and other algae.

Perhaps you meant:
psy·chol·o·gy
sīˈkäləjē/
noun
noun: psychology
the scientific study of the human mind and its functions, especially those affecting behavior in a given context.​

I was expecting an article about the successful falcon heavy launch in techspot but I guess optical illusion would be the next giant leap for mankind.

@ Kendrick. They are both optical illusions. You just are more invested in one of them.
How can only one photo in a "two photo comparison illusion" be an illusion on its own? What "illusion" do you see in just one photo that everyone else is missing? *nerd*
