The pictures are an optical illusion. Optical illusion (14 illusions). Double pictures of visual illusions: photos with explanations

It turns out that many of the mysterious pictures ( optical illusions- puzzles) so popular on the Internet, are actually reproductions of paintings by talented surrealist artists. These people know the laws by which our visual perception works and use these laws to create mysterious masterpieces that you want to look at again and again. Illusions from famous artists, you can see reproductions of their wonderful paintings in this article, we will also briefly talk about surrealism and its representatives from the world of artists.

Surrealism

Perhaps the most famous of the surrealist artists is Salvador Dali. But, based on the impression of the illusions created in the paintings, modern artists are not only not inferior to El Salvador, but in many ways they are ahead.. What is surrealism? This is an art movement that uses allusions and paradoxical forms. Surrealist paintings help you look at your surroundings with different eyes, see in surrounding reality something that may be hidden behind everyday life. Surrealist artists love to paint mystery paintings that make you think, peer and wonder. In their paintings, the background constantly changes places with the figure. Either you see a portrait of a man, or two women walking with umbrellas in the rain; or you look at the arches and columns, and suddenly you realize that you are already looking at skyscrapers that previously looked like arches. Yes, what can I say!? See and be amazed at how rich the human imagination is and what our brain is capable of. All pictures are clickable, click on them and they will become larger so you can see more details.

We present to you just one painting by Dali, since in his work he went too far from reality. This painting conveys the play of figure and background. In it, two nuns become the central part of the composition due to the fact that a human face is obtained from their figures. Most likely this face is a portrait real personality, since surrealists often depict people in this way. In the works contemporary artists you will see it more clearly. But we won’t write in detail about the artists themselves here; their biographies and other reproductions of paintings can be found on the Internet. Here we simply display reproductions with the artist’s name and (sometimes) the title of the painting. And you figure out how this can happen... from one horse there are two or more, from landscapes there are people, from curtains the sky and so on...

How suddenly, for Rob Gonsalves, the clouds become sails, and the girls become part of architectural structure…

Same principle here. The girls are not visible while you are looking at the sky, because in this case they are a reflection in the water.

This is also a painting by Gonsalves. The same principle is used. You won't notice the skyscrapers right away. What do they have to do with them on the shore? We see them as if from the sea.

Or here - how interesting the perspectives are intertwined in Rob’s painting. One goes forward, the other goes down, and it turns out that the boy is swinging on one tree, but under him there is another and there is another road, etc.

or here. This is the same principle as in the picture above.

Oleg Shuplyak. Ukrainian artist, who now lives abroad. He created a whole gallery of portraits famous people like this in an unusual way. Really impressive!

Well, it’s clear that this is a guy with sheep against the backdrop of a village landscape. How did all this become a portrait of Taras Shevchenko?!

Great! I wonder if Newton is one or both of these people? Or maybe there is a third one? I won't be surprised by anything anymore.

You won’t see Manet here right away. Girls with umbrellas are more noticeable. Although...When you see the picture for the first time and from afar, you don’t see the girls. Impressive.

Another interesting portrait.

Another familiar face. This time exclusively from a winter village landscape.

Octavio Ocampo

Also very interesting portraits. It seems like just two squirrels on a branch, but what a girl she turned out to be!

Another variation by this artist on the theme of a girl made from surrounding objects.

What do you think of this picture? You don't know what to look at!!!

Octavio loves riddles! Count if you can, how many horses are there?

Horses or girls? Where do you look most often?

We are accustomed to taking the world around us for granted, so we do not notice how our brain deceives its own masters.

The imperfection of our binocular vision, unconscious false judgments, psychological stereotypes and other distortions of worldview give rise to optical illusions. There are a huge number of them, but we tried to collect the most interesting, crazy and incredible of them for you.

Impossible figures

Impossible trident

Classic blivet – perhaps the most bright representative optical patterns from the category " impossible figures" No matter how you try, you will not be able to determine where the middle tooth originates.

Another shining example – impossible triangle Penrose.

It is in the form of a so-called “endless staircase”.

And also “The Impossible Elephant” by Roger Shepard.

Ames room

How does the Ames room work?

Movement Illusions

floating star

There are quite a few similar illusions of movement, that is, static images that appear to be moving. For example, the famous rotating circle.

Or yellow arrows on a pink background: when stare they seem to sway back and forth.

Caution: This image may cause eye pain or dizziness in people with weak vestibular systems.

Honestly, this is a regular picture, not a GIF! Psychedelic spirals seem to drag you somewhere into a universe full of strangeness and wonder.

Changeling illusions

Two classic illusions-shifters: nurse/old woman and beauty/ugly.

A more highly artistic picture with a trick - when turned 90 degrees, the frog turns into a horse.

Other " double illusions"have a more subtle background.

Girl/old woman

Old people/Mexicans

Lovers/dolphins

The list of such dual pictures can be continued endlessly:

In the picture above, most people see the Indian's face first, and only then look to the left and see the silhouette in the fur coat. The image below is usually interpreted by everyone as a black cat, and only then does a mouse appear in its outline.

A very simple upside-down picture - something like this can be easily done with your own hands.

Illusions of color and contrast

Gray squares

This trick is possible due to the way our brain works. A shadow without sharp boundaries falls on square B. Thanks to the darker "surrounding" and the smooth shadow gradient, it appears to be significantly lighter than Square A.

Green spiral

Is the dress white and gold or blue and black?

The explanation of the dress phenomenon is very simple: as in the case of gray squares, everything depends on the imperfect chromatic adaptation of our visual organs. As you know, the human retina consists of two types of receptors: rods and cones. Rods capture light better, and cones capture color better. Each person has a different ratio of cones to rods, so the determination of the color and shape of an object is slightly different depending on the dominance of one or another type of receptor.

Those who saw the dress in white and gold noticed the brightly lit the background and decided that the dress was in the shade, which means the white color should be darker than usual. If the dress seemed blue-black to you, it means that your eye first of all paid attention to the main color of the dress, which in this photo actually has a blue tint. Then your brain judged that the golden hue was black, lightened due to the sun's rays directed at the dress and the poor quality of the photo.

In reality the dress was blue with black lace.

And here is another photo that baffled millions of users who could not decide whether it was a wall in front of them or a lake.

Optical illusions are those effects of visual perception that occur involuntarily or consciously in a person observing certain images.

Such effects are also called optical illusions - errors in visual perception, the cause of which is the inaccuracy or inadequacy of the processes occurring during the unconscious correction of visual images. In addition, the physiological characteristics of the visual organs and the psychological aspects of visual perception also take part in the process of the occurrence of optical illusions.

Optical illusion, presented in this section of the site, consists of distorting perception by incorrectly estimating the length of segments, the size of angles, the colors of a visible object, etc. Its most popular types are illusions of depth perception, inversions, stereo pairs and illusions of movement.

Illusions of depth perception include inadequate reflection of the depicted object. Most famous examples Such illusions are two-dimensional contour pictures - when observing them, they are unconsciously perceived by the brain as single-convex. In addition, distortions in depth perception can lead to incorrect estimation of geometric dimensions (in some cases the error reaches 25%).

Optical illusion Inversion consists of depicting a picture, the perception of which depends on the direction of view.

Stereopairs allow you to observe a stereoscopic image by superimposing them on periodic structures. Focusing your gaze on the picture leads to the observation of a stereoscopic effect.

Moving illusions are periodic images, looking at them for a long time leads to the visual perception of movement from individual parts.

Do you see the frog and the horse in this optical illusion?

This picture is very famous. Turn it over to see how men see women after drinking 6 beers.

Mysterious face found on Mars. This is an actual photograph of the surface of Mars taken by Viking 1 in 1976.

Look at the four black dots in the center of the image for about 30-60 seconds. Then quickly close your eyes and turn towards something bright (a lamp or a window). You should see a white circle with an image inside.

Beautiful illusion of a moving bicycle (© Akiyoshi Kitaoka: used with permission).

Illusion of moving curtains (© Akiyoshi Kitaoka: used with permission).

Interesting optical illusion with perfect squares (© Akiyoshi Kitaoka: used with permission).

And once again perfect squares (© Akiyoshi Kitaoka: used with permission).

This is a classic - no need to explain.

There should be 11 faces in this picture. The average person sees 4-6, attentive people see 8-10. The best see all 11, schizophrenics and paranoids see 12 and more. And you? (Don't take this test too seriously, I heard there might be 13 people there.)

Do you see a face in this pile of coffee beans? Don't rush, it's really there.

Do you see squares or rectangles? In fact, there are only straight lines in different directions, but our brain perceives them completely differently!

It's time to do some eye exercises, have fun and stretch your imagination! In this collection you will find bright and unpredictable pictures and very interesting puzzles for those who like to double-check everything in person. The same drawing may contain several subjects at once, and some images may seem “alive.” Don't worry, this is completely normal.

Here are two different scenes in one picture at the same time. Some people see a bowl or a figurine, while others see people looking at each other. It's all about perception and focus. Switching from one plot to another is a good exercise for the eyes.

24. Bring the image first closer to your face, and then back


Photo: Nevit Dilmen

It may seem to you that the ball becomes voluminous and even takes on color. Be careful, they say that if you look at this drawing for too long, you may get a headache.

23. Wriggling figures


Photo: Wikipedia

At first, you may think that the columns and rows of white and green polygons are writhing, like a flag or waves. But if you hold a ruler up to the screen, you will realize that all the figures are located in in strict order and in a straight line, both vertically and horizontally. In the picture, all angles are equal to either 90 degrees or 45. Don’t believe your eyes, as they say.

22. Moving circles


Photo: Cmglee

For some, a simple glance is enough to immediately notice the movement, while others will have to wait a little. But sooner or later you will definitely feel that the circles in this picture are rotating. In fact, this is an ordinary picture, and not an animation at all, but ours has a hard time coping with such a set of colors and shapes at the same time, and it’s easier for him to decide that something is rotating on the screen.

21. Red lines on a colored background


Photo: Wikipedia

The red lines in the picture appear to be curved, but it is easy to prove otherwise with a simple ruler or even a piece of paper. In fact, this optical illusion is achieved using an intricate pattern in the background.

20. Black tops or bottoms of bars


Photo: Wikipedia

Of course, the black edges are the tops of the drawn bricks. Although wait... No, that’s not true! Or so? It’s not easy to figure it out, although the picture doesn’t change at all, unlike our perception.

19. Optical plug

Photo: Wikipedia

This drawing is a little reminiscent of the picture from point 23, only now there is also a giant fork. Although if you look closely, it may turn out to be something completely different...

18. Yellow lines


Photo: Wikipedia

Believe it or not, but in the image there are 2 yellow lines of exactly the same length. The deceptive prospect of black bars can be confusing, but we advise you to take up the ruler again.

17. Spinning circles


Photo: Fibonacci

If you look strictly at the black dot in the center of the picture and do not move your head, circles around it will begin to rotate. Try it!

16. Moving squiggles


Photo: PublicDomainPictures.net

This psychedelic picture is a real mystery for our brain. To peripheral vision, it always seems that some kind of movement is happening around the edges. No matter how hard you try, the squiggles will still move somewhere nearby, and not where you are looking.

15. Gray stripe


Photo: Dodek

It probably seems to you that the stripe in the center changes its color from one end to the other, as if someone’s shadow is falling on it. In fact, the center line is one, and the easiest way to check this is with 2 sheets of paper. Cover the top and bottom of the drawing and you'll see what it's all about. The only thing that changes in this image is the background color.

14. Black shadows


Photo: Wikipedia

Fascinating picture! It either dazzles your eyes or makes you dizzy, so don’t look at the screen for too long.

13. Fluttering pattern


Photo: Aaron Fulkerson / flickr

It feels like the wind is blowing across the surface of the field... But no, this is definitely not a GIF. Although it’s hard to believe if you look at the image, moving your gaze from one point to another. If you look strictly in the center, the picture should gradually freeze or at least slow down.

12. Triangles and lines


Photo: Wikipedia

These rows of stuck triangles appear uneven, as if they were spaced diagonally. In fact, they are still drawn parallel to each other. Is there a line?

11. Cow


Photo: John McCrone

Yes, it's a cow. Seeing it is not so easy, and sometimes it takes a little time, but if you look closely, you will definitely see not only random lines and spots, but also an animal. Do you see?

10. Drowning floor

Photo: markldiaz/flickr

It may seem as if the center of the picture is drowning or being pulled in by something. In fact, all the squares are the same size and shape, they are located evenly and do not float anywhere. The illusion of distortion is created by white dots along the edges of some squares.

9. Old woman or young girl?

Photo: Wikipedia

And this is a very old, almost classic, optical illusion. Everyone manages to solve the picture differently. Some people stubbornly see a young girl with beautiful cheekbones, while others are immediately struck by the huge nose of an old woman. But if you try, you can see them both. It turns out?

8. Blackheads


Photo: Wikipedia

This optical illusion creates the impression that small black dots are constantly moving in the painting. When you look at different parts of the drawing, they either appear at the intersection of lines or disappear. How many points can you see at the same time? It's very difficult to calculate!

7. Green whirlwind


Photo: Fiestoforo

If you look at this picture long enough, it may seem like you are being sucked into a vortex funnel! But this is a regular flat image, not a GIF. It's all about optical illusion and our brain. Again.

6. More spinning circles


Photo: markldiaz/flickr

Here's another absolutely stunning variation on a static image. Due to the complex colors and shapes of the details of the design, it seems that the circles are rotating, but in reality this is not the case.

5. Poggendorff illusion


Photo: Fibonacci

Here is a classic optical illusion, named after the German physicist I. K. Poggendorf. The answer lies in the location of the black line. If you look at the left side of the picture, it seems that the blue line should be a continuation of the black one, but on the right side of the picture you can see that it is the red stripe that completes it.

4. Blue flowers


Photo: Nevit Dilmen

Another optical illusion that will seem like a gif to you. If you look at this drawing long enough, the flowers will begin to spin.

3. The Orbison Illusion


Photo: Wikipedia

This is another very old optical illusion, drawn by the American psychologist Orbison back in the 30s of the 20th century. The red diamond in the center is actually a perfect square, but the blue lines in the background make it look like it's a little warped or rotated.

1. Zöllner optical illusion


Photo: Fibonacci

Here is another classic example of a geometric illusion, in which long diagonal lines seem to point toward the different sides. In fact, they are parallel to each other, but short strokes across the lines confuse our brain and create a sense of perspective. Astrophysicist Zöllner drew this illusion back in 1860!

An optical illusion is a trick of human vision. Observations of some images leave visual illusions in our minds.

Optical illusion is the unreliable perception of certain visual information. A person, looking at an illusion, incorrectly estimates its size or shape, creating a deceptive image in his mind.

The reason for erroneous perception is the structural feature of our visual organ. The physiology and psychology of vision allow us to make the wrong final result and instead of round shapes, a person is able to see square ones, and large pictures will seem small.

Illusion - error of visual perception

Optical illusion can be divided into several main types:

• incorrect color perception
• misperception based on contrast
• misperception of object size
• incorrect perception of image depth
• twisted illusion
• "shifter"
• illusions that move
• 3D pictures
• optical illusion contour

The human brain can react deceptively to some images. It seems that the image moves or even changes color only due to the fact that the brain perceives the visible light of some pictures.

Moving pictures optical illusion, photo

One of the most popular are the so-called moving pictures. Secret of this type lies in color and contrast perception.

Just look at the center for a few seconds of this drawing, then look away to one side of the salad frame of the image, as the picture literally “floats.”

This illusion can be classified into two types: “curvature of shape” and “moving illusion”. Firstly, the uneven placement of the cubes allows us to conclude that the lines are crooked.

However, they are absolutely smooth. Secondly, if you move the picture up and down using the slider on your monitor on the right, you can see how the cubes move and run.

Thanks to the textured image, it seems that the squares in the center of the picture are moving.

Thanks to the contrasting image of the round disks, it seems that they are moving in different directions: clockwise and counterclockwise.

The patterns in the picture are of different sizes and stand out with bright contrasting colors. This is why the lines and curves appear to be moving.

What kind of visual illusion pictures are there for children?

• Visual illusions are one of the most popular intellectual entertainment for children. Observing such pictures allows you to develop your child’s thinking.
• He tries to understand why this happens, that what is desired is not presented as reality.
• In addition, groups of eye muscles are exercised. This helps improve blood circulation to the optic canal, which means it serves as a kind of prevention of blindness and other problems.

While observing illusions, the child exercises his logical thinking and develops his brain.

The most popular illusions for children:

This illusion helps the child understand which animal is shown in the picture: a cat or a dog. The child analyzes everything external features and remembers the characteristics, in addition, he tries to visually reverse the image, which trains his eye muscles.

This illusion provides the child with the opportunity to see a three-dimensional image. In order to do this, you need to bring your face closer to the image, direct your gaze to the middle, diffuse your vision for five seconds and then quickly focus. This activity intensively trains the eye muscles and allows the child to develop vision.

Uniform prints located mirror to each other allow the baby to find common features external parameters in different animals.

This image allows you to develop abstract thinking: in the proposed picture you can see a simple branched tree. But if you read the contours correctly, the image of a newborn child will appear before your eyes.

What are hypnosis pictures, optical illusion?

Some images are called “pictures of hypnosis” because they are capable of misleading and a kind of trance, when a person diligently tries to understand the secret of the drawn objects and why they move.

There is a belief that if you look for a long time at the center of a moving image, a person imagines himself plunging into a deep tunnel without a bottom or edge. It is this immersion that distracts him from other thoughts and his trance is comparable to hypnosis.

Illusion pictures in black and white, optical illusion in contrasts

Black and white colors- are absolutely opposite. These are the most contrasting colors of all. Looking at such a picture, the human eye literally “doubts” which color to pay the main attention to, and that is why it turns out that the pictures “dance”, “float”, “move” and even appear in space.

The most popular black and white illusions:

The secret of the image is that the lines on the lines are drawn in different directions and that is why it seems that the lines are not at all parallel.

These images allow us to see two images in one picture. The drawing is based on the principle of contour and contrasts.

In this illusion, for the effect you need to look for a long time at the red dot located in the image.

One minute will be enough. After this, your gaze is averted to the side and on any object you see what you previously observed only on the monitor.

What is optical illusion 3d pictures?

This type of illusion allows a person to literally “break his brain.” This is because the picture displays the arrangement of objects in such a way that, firstly, they become three-dimensional on a plane, and secondly, sometimes they are too difficult to understand.

This picture makes it unclear to a person the location of objects: their sides and surfaces. Nevertheless, the drawing is perceived in volume.

More complex images require a person to peer into the depths of the picture for a long time. It is worth completely dissipating and splitting vision and after some time sharply restoring it.

On a completely flat picture it will appear volumetric figure(V in this case woman) with clear contours.

Optical illusions pictures optical illusions

Optical illusions are errors that can occur in our vision. The causes of optical illusions are errors of perception.

While looking at a picture, inexplicable movements, disappearances and appearances may occur. All this is justified physiologically and psychological aspect visual perception.

The secret of the illusion is that when we notice a small black object in the center, we do not pay attention to our surroundings.

The unclear image of the contours allows us to see that the elephant has eight legs instead of four.

Contrasting colors and unclear boundaries of the picture allow the image to literally vibrate the moment we look at it and remain immobilized when we turn our gaze to something else.

Based on a mirror image with exact repetition of all forms.

Optical illusion pictures: dress, explanation of the illusion

• The famous online “virus” and the “blue or gold dress” joke are based on vision perception, depending on individual characteristics each person
• Once upon a time, everyone received a picture on social networks from friends with the caption “What color is the dress?” And many of your friends answered this question in completely different ways: either blue or gold
• The secret to perceiving a picture lies in how your visual organ is built and under what conditions you observe this picture.
• In the retina human eye in each specific case there is a certain number of cones and rods. It is the quantity that plays the role of perception: for some it will be blue, for others it will be golden

It is important to pay attention to the fact of lighting. look at the image in bright light and you will see a blue dress. Go into a dark room for half an hour and then look back at the picture - most likely you will see a golden dress.

Double pictures are an optical illusion, what's the secret?

As mentioned earlier, the secret of this illusion is hidden in the complete repetition of the lines of the drawing when it is mirrored. Of course, this cannot be done in practice with every picture, but if you carefully choose the form, you will get quite an interesting result.

Looking at this image, you need to decide for yourself: “What do you see first?” Of the possible options, you will see a young girl, turned in profile with a feather in her headdress, or an old woman with a long chin and a large nose.

Among the more modern versions of the double image, we can distinguish paintings that simultaneously depict two separate drawings. In such cases, the features of one image are read in different lines.
