In this image, how many faces do you see? Most people cannot find more than four.

Do you have the impression that your brain is extremely adaptable to details, Do you think you’re more aware of things that others aren’t, and that you’re more likely to come up with a unique explanation for things that amazes people.
Illusions, according to researchers, illustrate how your brain works and how it relies more on your perception than your vision.
There are 13 faces in the picture:
The first four prominent ones

These four faces stand out among the 13 secret faces and are easily recognized by many users. The reason viewers perceive these photos first could be due to their location, which is near the center, as well as the size of these images.
When we look at an image, our eyes are drawn to the items in the center, and images that are larger in size naturally appear first.
The two faces on the side

These two faces, of varying sizes, appear in front of our eyes. Despite the fact that the one on the extreme right is larger, our vision ignores it because of its position in the image.
The other image is very little and is sandwiched between the center image and the larger image, making it difficult for human eyes to distinguish between them.
The four on the top

Four faces are melded within the trees in the upper half of the photograph. Only when you look closely through the deep forest can you see the eyes, noses, and lips of the people.
The three difficult ones

These two faces are hidden among other faces and elements, making them difficult to notice.
