Optical illusion photo ideas
A lady has blown up an image on her screen, is squinting at it, and keeps wandering back and forth to see it from different angles.
But whatever she's trying to do, it isn't working.

One of the specialists explains, the weirdly glossy look of the legs is an illusion. An Instagram user created it by accident.
Amazing optical illusion photo
He had some white paint left on his brush and put random lines on his legs, turned out to be an entirely complex picture for everyone on the internet.
All he can see is bizarrely glossy legs. But some people don't see the shine at all — just some boring old white paint.
The illusion is freaking people out all over the internet.
Are these legs shiny and oily or are the legs with white paint on them?
Optical illusion photography trick
Why do some people see the shine? Why do others see the white paint?
The theory is The smaller it shows up on your screen, the more it looks like shine.
The ideas aside, there's a deeper level to what's going on here. The photo is revealing that our eyes aren't windows onto the real world. Instead, they gather lots of bits of information that your brain assembles into a consistent stream of images based on what it knows about the reality.
Illusions are flaws in that system that shine a light on how amazing it is in the first place.

The psychologist Claus-Christian Carbon explains in his paper "Understanding human perception by human-made illusions" why optical illusions such as these legs or The Dress are so exciting:
"We can ... interpret false perceptions as a sign of our incredible, highly sophisticated and efficient capabilities of transforming sensory inputs into understanding and interpreting the current situation in a very fast way to generate sufficient and goal-leading actions in real time. ... By taking into account how correctly we act in most everyday situations, we can experience the high 'intelligence' of the perceptual system quite quickly and intuitively."
In other words, when your brain misinterprets a visual clue — like the lines on Culverhouse's legs — it lets us know a bit more about how it builds images of the world the rest of the time when it works correctly.
And for some people, such as Erin, the visual system works too well to trick — even with an illusion this efficient.
