For a long time, people dealt a lot with negatives that were initially captured by analogue cameras and needed to be developed. However, over time, technology has managed to suppress this process. Still, these images can be very interesting, as in this optical illusion of the negative photo.

Unravel the illusion: which direction is this circle moving?
Have you ever stopped to think about what a negative photo is and why it gets that name? In this case, they are called negative because here the originally light colors become dark and vice versa.
Thus, the process of developing a photo, in the past, consisted of recovering the original tonality through conversion with chemical substances. However, what few know is that you can perform this conversion directly in our eyes.
This happens when we face a negative image with attention. At that moment, our color receptors will send continuous and intense messages to our brain. Then, as there is no harmony between the receivers, the mind will convert the images through its negative.
For many it is simply impossible to think that our brain can convert colors and transform images. But they certainly don't know the power our brain has to configure information.
But, if you still don't believe it, then see how this optical illusion works. To start, look at the image on the left very carefully and keep your eyes fixed on it for at least 30 seconds.
Then all you have to do is shift your gaze to the blank space beside you and, if you need to, blink a few times. Then you will be able to recognize the contours of the image that appears before your eyes.
You may even notice how, slightly, the colors of the image also begin to emerge. Certainly this can give a bug in the minds of many people, but we cannot say that it is not a very interesting experiment!
