Take a look at these two photos, which first appeared on Imgur. On the this moment more than 1.4 million viewers broke their brains over the solution. You see, they are different - the right image shows the street from a high angle. That is, the roads in the picture do not look parallel to each other.
In fact, these are two completely identical photos. The caption to them says that two absolutely identical pictures taken from the same angle are combined here, literally “pixel by pixel”.
But almost everyone who looks at this image writes that the author is trying to deceive them. To most viewers, the street in the right picture seems to lean more to the right, while the left one is straight. Some see that the roads generally lead in different directions, as if one branched into two. And almost no one perceives these roads as parallel to each other.
There were also those who did not believe that these were the same images even when it was proved that they were the same photographs. The pictures were superimposed on each other in a GIF, and it became clear that they were no different.
Why the human brain perceives these images as different, users of the same Imgur and Reddit website explained.
One of them suggested that the photographs are different to the eye, because the two streets merge at the bottom of the picture. The brain perceives what it sees as one image with a fork in the road, and therefore the street in the picture on the left should be at a greater angle than in the image on the right. If you close the bottom of the pictures to the headlights of a white car, they look the same.
In addition, to perceive these two roads as parallel, the eye must see them meet at the same point on the horizon. And in the photo, the roads end at different points on the horizon, the same goes for the borders and other details of the two paintings, and therefore they do not seem to be parallel.
Two photographers who didn't know each other shot the same storm in the same place and got almost identical shots.
On March 3, during a winter storm, American photographer Ron Riesman traveled to the Great Island Common, New Hampshire, hoping to capture high waves crashing against the Weilback Lighthouse a kilometer from the coast.
On the spot, he set up a tripod, set up a Canon 5D Mark IV with a Sigma 150-600mm lens, and settled himself against a tree to somehow hide from the sharp gusts of the north wind.
When the waves broke, he began to shoot. Most of the shots taken in 45 minutes failed, but a couple of shots turned out very well. After shooting, right in the parking lot, he posted one of them on Instagram. Then, already at home, he looked through all the pictures, chose one, processed it and posted it instead of the first one.
After a local TV station (with Risman's permission) posted his photo on their Facebook page, likes and comments rained down on the photographer. In one of them, one of the users accused Ron of stealing a photo of another photographer from New England, Eric Gendron.
Riesman assured the commenter that the photo was not stolen and that he had the original RAW file, then went to that second photographer's page. And he was shocked. The picture of Gendron was exactly the same, taken at exactly the same time and, apparently, from the same place and from the same angle.

Photo by Eric Gendron If we forget about the difference in processing, the photos looked identical, except for a slight difference in the water in the foreground. Even the wave caps, although they were in different places, were identical in size and shape - and moving them in Photoshop using the “Stamp” is very simple. So Risman thought - maybe just his photo was stolen?
Initially, Ron had only a low-resolution picture of Henrdon from social networks. It was impossible to make out the smallest details on it, which would confirm that both photos were originals. He layered two images on top of each other in Photoshop and was amazed at how they matched each other: waves, a lighthouse, everything was almost pixel-perfect. But still, small differences did not allow him to immediately declare that Eric Henrdon stole his picture.
A little later, another photographer compared the photographs of Riesman and Gendron and noticed that the distance between the elements of the fence at the top of the lighthouse differed slightly. This indicated that Gendron was somewhat to the left of Riesman at the time of the shooting.
Also, since Gendron's 60D has an APS-C sensor, Eric had to be slightly further away from the shooting location or use a smaller focal length to compensate for the 1.6x crop factor. This would also explain the difference in the position of the lambs.
However, the positions of the lighthouse and the waves are exactly the same - and the fact that the pictures were taken by two different photographers, independently of each other, becomes even more amazing.
When Eric Gendron discovered messages from Risman and other photographers, he immediately provided EXIF data for his shot, and was also surprised that the frames turned out to be identical. What makes this story even more amazing is that they were not filming some planned event (a sports competition or a shuttle launch, for example), but a natural phenomenon.
Both photographers did not know each other, both randomly chose this place for shooting. They used different cameras (Canon 60D and 5D Mark IV) with sensors of different sizes (plus, 60D shoots bursts up to 5.3 fps, and 5DMKIV - 7 fps), but both worked with a focal length of 600 mm. And the settings were very similar (f/8, ISO 400, shutter speed 1/1600 and f/8, ISO 320, shutter speed 1/1000). And finally, both chose the same photo from all taken that day.
As it turned out in the process of communication, the photographers were 28 meters from each other. Gendron sheltered from the wind in a picnic arbor, Risman behind a tree.
Risman specifically searched Google for similar stories to find out how often this happens, and could only find one article dated 2011, when two photographers filming a surfing competition in Huntington Beach got an almost identical image of a surfer and waves around.
“If you’ve taken a series of shots of water, you know how different shots can be, even if the time difference between them is only 1/7 of a second,” Risman writes, “Besides, I have been teaching master classes in astrophotography for five years , and we used to have more than 200 photographers shooting the same subject at the same time, with similar cameras and lenses, even shooting in series for time-lapses - but so far I have not seen two such identical shots that would actually be clones of each other” .
“So far this is rare, but over time, I think it will happen more often, because cameras are getting faster, and photographers spend more time preparing for shooting. Now this happens with stationary or slow moving objects (buildings, sunrise/moon), but almost never with moving water.”
“On March 3rd, during a big storm on the East Coast, I headed out to the ocean to capture wave activity. The road took me to the Great Island Common, New Castle, New Hampshire, where the Wailback Lighthouse is visible, standing 12 kilometers from the coast. I was hoping to photograph the big waves crashing around the lighthouse and Mother Nature did not disappoint.
Great Island Common - extensive outdoor park where people come for a picnic in summer and warm winter.
Upon arrival, I set up my Canon 5D Mark IV DSLR with a Sigma 150-600mm lens on a tripod, positioned to the right of the tree to shelter from the gusts of the north wind. Many people know how difficult it is to keep a 600mm lens stable in strong winds, even when using a tripod.
I set up the camera and waited until I saw the wave begin to hit the lighthouse. Then I continued to shoot until the series ended, not knowing how the wave would behave. Most of the shots failed, but about three shots out of all that were taken over the course of about 45 minutes turned out to be pretty decent.
When I got home, I chose one image to edit and uploaded it to Instagram. When a local TV station shared the photo on their Facebook page (with my permission), it was immediately followed by numerous reposts, comments and likes.
But one comment said I stole an image from another New England photographer, Erica Gendon. I first told the commenter that this was really my shot and that I had the original RAW file, and then I looked at another photographer's page and was amazed. We had the same images, shot with millisecond precision, seemingly from the same perspective and location.
This photo was taken by me, Ron Riesman.

Leaving out the Lightroom processing, the photos look virtually identical at first glance, except for the water in the foreground and the different placement of a few patches of white foam. But even they turned out to be identical in size and shape, and I know that such elements are easily moved using the stamp tool in Photoshop, so I was worried: maybe my image was stolen and slightly changed?
Initially, I only had access to a low-res image of him, so I couldn't make out the smallest details, which eventually helped me make sure we both had the originals. But after overlaying the images in Photoshop, I was amazed: the lighthouse and the waves matched almost to the pixel. The differences in the water in the foreground and the white caps of foam on the horizon kept me from claiming he stole my shot.
Another local photographer compared my photo with the higher resolution version of Eric's and noticed that the distance between the vertical strips of iron railing around the top of the lighthouse was slightly different compared to my image. This meant that the other photographer was most likely standing slightly to the left of where I was.
Location of photographers.
Because the 60D that Gendon shot with has an APS-C sensor, he was probably a little further away, which would have compensated for the 1.6x crop factor or used a shorter focal length. And that would explain the difference in the location of the white foam.
However, the lighthouse and the breaking wave exactly matched, which is surprising, since the pictures were taken by chance by two different photographers.
I didn't know Eric, each of us chose this place randomly, we both shot with different cameras (60D and 5D Mark IV) with different sensor sizes; in 60D continuous shooting mode at a frequency of 5.3 frames per second, 5D Mark IV - 7 frames per second. We both used 600mm focal length; aperture, shutter speed and ISO settings are also almost the same (F/8, ISO 400, 1/1600s and F/8, ISO 320, 1/1000s). We ended up both choosing the same photo from that day to post online, only to find out later that we were only 28 meters apart.
I did a Google search to check how often this happens, and I could only find one article from 2011 that featured two photographers filming a surf competition in Huntington Beach who took nearly identical shots of a surfer and the movement of a wave.
If you've shot water in continuous burst mode, you know how different each exposure is, even if the time difference is only 1/7 second between shots. For five years, I have been running night sky photography workshops with more than 200 photographers who often focus on the same subject, shooting with similar cameras and lenses at the same time, even using continuous time-lapse photography. But until now, I have never seen two images so similar, as if they were virtual clones.
While this is a rare occurrence, I think as cameras get faster and photographers get better prepared for shooting, this kind of thing will become more frequent. This happens daily with stationary or slow moving objects (buildings, sunrise/moon), but almost never with moving water.”
You always need to think in time about how to develop a child's memory. Some will say that this is a natural gift and does not need to be developed. Of course, children's memory tends to develop naturally, but without the help of parents, its deep reserves will remain unused. For the effective development of memory, there are many games that children play with pleasure.
The game in front of you is one of those games called "Find two identical pictures". This colorful game contains a lot of different cards featuring funny animals. Each card has its own pair, during the game you need to find it. To do this, the child must first choose one card, then the second, if they match, then these cards are no longer closed, and the baby is one step closer to winning. The game has six different difficulty levels. Even the smallest children can play this game.
The game develops memory, imaginative thinking, in addition, games of this kind introduce the baby to the outside world and activate cognitive activity. This game is a mindfulness game that will surely appeal to all children without exception.
