illusion of sex

By looking at these two photos , whom you think is a female and whom is the male?

The faces are actually versions of the same androgynous face (neither male, nor female). One face was created by increasing the contrast of the androgynous face, while the other face was created by decreasing the contrast. The face with more contrast is perceived as female,(the face at your left) while the face with less contrast is perceived as male(at your right). The Illusion of Sex Change demonstrates that contrast is an important cule for perceiving the sex of a face, with greater contrast appearing feminine, and lesser contrast appearing masculine.
