As this image gets larger, what do you see?
At normal viewing distance, healthy eyes should be able to pick up the fine lines on Einstein’s face, causing the brain to disregard Marilyn Monroe’s image altogether. MIT scientist Aude Oliva created this hybrid image made from the high spatial frequency components of a picture of Albert Einstein and the low spatial frequency components of a picture of Marilyn Monroe.

From close up, Albert Einstein should be seen. At a greater distance or smaller size, Marilyn Monroe should be seen. The Marilyn/Einstein hybrid image was created originally for the March 31st 2007 issue of New Scientist magazine
