2 in 1 paintings with optical illusion. The most incredible optical illusions

Optical illusion is an unreliable visual perception of any picture: incorrect assessment of the length of segments, the color of the visible object, the size of the angles, etc.

The reasons for such errors lie in the peculiarities of the physiology of our vision, as well as in the psychology of perception. Sometimes illusions can lead to completely incorrect quantitative estimates of specific geometric quantities.

Even looking carefully at the “optical illusion” picture, in 25 percent or more of cases you can make a mistake if you do not check your visual assessments with a ruler.

Pictures of optical illusion: size

So, for example, let's look at the following figure.

Pictures of optical illusion: circle size

Which of the circles located in the middle is larger?

Correct answer: the circles are the same.

Pictures of optical illusion: proportions

Which of the two people is taller: the dwarf in the foreground or the person walking behind everyone?

Correct answer: they are the same height.

Pictures of optical illusion: length

The figure shows two segments. Which one is longer?

Correct answer: they are the same.

Pictures of optical illusion: pareidolia

One type of visual illusion is pareidolia. Pareidolia is an illusory perception of a specific object.

Unlike illusions of perception of length, depth, dual images, pictures with images that are specially created in order to provoke the emergence of illusions, pareidolia can arise on their own when viewing the most ordinary objects. So, for example, sometimes when examining a pattern on wallpaper or a carpet, clouds, spots and cracks on the ceiling, you can see fantastic changing landscapes, unusual animals, people’s faces, etc.

The basis of various illusory images can be the details of a real-life drawing. The first to describe such a phenomenon were Jaspers and Kahlbaumi (Jaspers K., 1913, Kahlbaum K., 1866;). Many pareidolic illusions can arise when perceiving well-known images. In this case similar illusions may occur simultaneously in several people.

For example, in the following picture, which shows the World Trade Center building on fire. Many people can look at it scary face the devil.

The image of the devil can be seen in the next picture - the devil in the smoke


In the following picture you can easily distinguish a face on Mars (NASA, 1976). The play of shadow and light has given rise to many theories about ancient Martian civilizations. Interestingly, late photographs of this area of ​​Mars do not show a face.

And here you can see a dog.

Pictures of optical illusion: color perception

Looking at the drawing, you can observe the illusion of color perception.


In fact, the circles on different squares are the same shade of gray.

Looking at the following picture, answer the question: are the chess squares on which points A and B are the same or different colors?

It's hard to believe, but yes! Don't believe me? Photoshop will prove it to you.

How many colors are you drawing in the following picture?

There are only 3 colors - white, green and pink. You might think there are 2 shades of pink, but that's actually not the case.

What do these waves look like to you?

Are the brown wave stripes colored? But no! It's just an illusion.

Look at the following picture and say the color of each word.

Why is this so difficult? The fact is that one part of the brain is trying to read the word, while the other perceives the color.

Pictures of optical illusion: elusive objects

When looking at the following image, look at the black dot. After some time, the colored spots should go away.

Do you see the gray diagonal stripes?

If you look at the center point for a while, the stripes will disappear.

Pictures of optical illusion: shapeshifter

Another type of visual illusion is shapeshifting. The fact is that the image of the object itself depends on the direction of your gaze. So, one of these optical illusions is the “duck hare.” This image can be interpreted as both an image of a hare and an image of a duck.

Take a closer look, what do you see in the next picture?

What do you see in this picture: a musician or a girl’s face?

Strange, it's actually a book.

A few more pictures: optical illusion

If you look at the black color of this lamp for a long time, and then look at a white sheet of paper, then this lamp will be visible there too.

Look at the dot, and then move away a little and move closer to the monitor. The circles will spin in different directions.

That. the features of optical perception are complex. Sometimes you shouldn’t believe your own eyes...

Snakes crawl in different directions.

Aftereffect illusion

After throughout long period continuously look at the image, for some time then there will be some impact on vision. For example, prolonged contemplation of a spiral leads to the fact that all objects around will rotate for 5-10 seconds.

Shadow figure illusion

This is a common type of erroneous perception when a person guesses a figure in the shadows with peripheral vision.

Irradiation

This visual illusion, leading to distortion of the size of an object placed on a background of contrasting color.

Phosphene phenomenon

This is the occurrence of unclear points different shades in front of closed eyes.

Depth perception

This is an optical illusion, implying two options for perceiving the depth and volume of an object. Looking at the image, a person does not understand whether an object is concave or convex.

Optical illusions: video

Look at the photo of the cake. Do you see the red strawberries? Are you sure it's red?

But there is not a single scarlet or even pink pixel in the photo. This image is made using shades of blue color, however, we still see that the berries are red. The artist used the same effect of changing lighting, which divided the world into two camps due to the color of the dress. And this is not the most delicious picture of the master of illusions. We share with you the most interesting things.

1. Hearts change color

In fact, the heart on the left is always red, and the one on the right is purple. But these stripes are confusing.

2. The ring turns white and black

What color is the ring in this picture? In fact, it consists of stripes of two colors - blue and yellow. But what happens if you break the picture in half?

What will happen is that the half of the ring will appear white on the left and black on the right.

3. Trickster Spirals

We see two types of spirals: blue and light green. But they are all the same color: R = 0, G = 255, B = 150. You can check and guess what the trick of this illusion is.

4. Deceiver flowers

Flower petals appear blue above and green below, although they are the same color. These flowers also spin in opposite directions.

5. Strange eyes

What color are the doll's eyes? Red, blue, green or yellow? Gray. In all cases.

6. Jellyfish that grows

Take a closer look. The artist believes that this is a jellyfish that is increasing in size. Whether it’s a jellyfish or not is debatable, but it’s true that it grows.

7. Beating Hearts

When we look from one row to another, our hearts begin to pulsate.

8. Blue tangerines

There are no orange pixels in this image, only blue and gray shades. But it's so hard to believe.

9. Mysterious rings

These rings deceive three times. First, if you look at the picture, it looks like the inner ring is compressing while the outer ring is expanding. Second, try moving away from the screen and moving closer to it again. During movement, the rings rotate in opposite directions. Thirdly, these rings also change shades. If you look at the picture closely and focus your gaze on the center, the inner ring will appear redder than the outer one, and vice versa.

10. Umbrellas

In these pictures we see umbrellas with two rings of different colors. In fact, on each umbrella, both rings are the same color.

11. Glowing cubes

Thanks to the play of colors, it seems that radiance emanates from the corners.

12. Field covered with waves

The field is filled with squares, but where does the illusion of movement come from?

13. Rollers

It's not animated, but the videos seem to be spinning!

14. Creeping lines

Everything crawls in different directions, although there is no animation here either.

15. A ball that won’t roll away anywhere

It seems that someone left a ball with the same pattern on the tiled floor, which is about to roll away.

16. Stereogram

And this is a stereogram. If you look at the drawing with the focus behind the image, you will see a circle in the middle. Try to get as close to the drawing as possible (almost touch your nose to the screen), and then slowly move away from it without moving your eyes. At some distance the circle should appear by itself.

17. Crawling snakes

It seems that they will crawl out of the picture after all.

18. Working gears

It's hard to believe that this isn't animation, even though the gears are turning.

19. Elusive buttons

If your eyes have not betrayed you yet, then try to stop all these buttons.

20. Calming fish

They say that to relieve stress you need to watch the fish in the aquarium. There is no aquarium, but the swimming fish are still there.

The coolest optical illusions! They will help your brain switch gears and distract you a little, but be careful: as we know, overdosing on medication can be dangerous!

Optical illusion- an impression of a visible object or phenomenon that does not correspond to reality, i.e. optical illusion. Translated from Latin, the word “illusion” means “error, delusion.” This suggests that illusions have long been interpreted as some kind of malfunction in the visual system. Many researchers have been studying the reasons for their occurrence.

Be careful!

Some illusions can cause tearing, headaches and disorientation in space.

Interior illusion

Chessboard squares

Optical illusions are nothing more than an optical illusion of our brain. After all, when we look at a picture, our eye sees one thing, but the brain begins to protest and claim that this is not at all what it is. So it turns out that illusions are created by our mind, which begins to analyze the color, the position of the light source, the location of edges or corners, etc. Thanks to this, the correction of visual images occurs.
Be careful! Some illusions can cause tearing, headaches and disorientation in space.
