Your eyes and brain get lazy. When they see something and it doesn’t change for a while, they decide to just assume it’s still there until it gets the signal otherwise.

When you look at the negative, your eyes assume the negative is there until you look at a plain white image, where you see the difference between the white and negative images (the normal image) until your eyes get the memo that things have changed.
