Wondering how this possible?
Well this is the possible explanation.
When you look at the white layer on the picture, what you should see is a full color representation of the image as your retina/brain processes the negative image.
Our visual system is constantly
processing input and can fool us or create illusions from retinal or cortical processes. This illusion example is called a negative after-image that is caused by adaptation of the photoreceptors in the retina.
Forcing ones eyes to fixate on a point (in this case the grey dot
on Laura Galloway ‘s nose reduces the normal jitter or micro saccades that constantly occur as we scan things in our visual world.
The micro saccades normally cause images to dance over the surface of the eye eliminating the possibility of too much adaptation if an image remains static over one group of photoreceptors for too long.
In fact, if one were to eliminate all movement of the eye, and we were to fixate on a single point, our
perception of our visual world would fade away.
So, what happens in this illusion is that when we look from the first image to the white space or to
a large plain surface, the photoreceptors that become adapted no longer signal effectively, but the photoreceptors surrounding the adapted photoreceptors strongly signal perhaps signaling opponent cells in the lateral geniculate nucleus (LGN) involved in color vision.
Though other evidence from Dacey, He, and MacCleod. suggests that opponency is not necessary to explain the illusion.
To those who didn't see the beauty others saw. I just reinverted the picture for it to be visible for everyone.
