Negative Picture Illusion? Afterimage Illusion
How This Visual Illusion Works

A negative picture is the inverse of a normal, or positive, image. In a negative picture, areas that are white or light appear dark, and darker areas appear to be light. Usually, photo negatives are turned into positive images in a darkroom. But with the negative picture visual illusion, your visual system and brain can briefly create a color image from a negative photo.

How to Create the Negative Picture Illusion/Afterimage Illusion
To see the negative picture illusion:
1) Stare at the dots on the woman's face in the picture for 30 seconds.
2) Turn your eyes immediately to the right white image on the right or a white wall.
3) Blink quickly several times.

You should see an image of a woman in full color, although only briefly. If you are having trouble seeing the effect, try staring at the negative image a bit longer or adjusting how far you are sitting from your computer monitor.

Because not everyone can see it. Take a long, hard look at the picture and see if you’re one of the special ones who can:

This illusion requires you to stare at the dots on the woman's nose for 30 seconds, then look to the right of the image at the white blank space or a white wall. Blink serval times and you should see a flicker of the full color photo of the woman.

This is down to the way our brains interpret imagery and colors and in this case is known as "negative afterimage".

The reason some people are able to visualize the woman in full color is down to cells we have in our eyes known as ganglion (gang·glee·n) cells, which send coded messages to the brain identifying pairs of primary colors.

Dr Juno Kim from the University of NSW School of Optometry and Vision Science to Daily Mail Australia explains:
"The code for all the hues we can experience in the light spectrum – this information is relayed from the back of the eye to the brain via three opponent neuron channels.

As well as black and white, we also have a red and green and a blue and yellow channel, which is the one that comes into play here. Because you stare at a blue background for a prolonged period of time, as soon as you shift your eyes to a ‘uniform’ background – the white space in this instance – the cell declines and starts to project the opposite color.

It is those yellow hues that, for some, reveal the woman in the original negative image as in full color.
