Face Off
Question:
Can You Change Your Face with
Me?
Instructions:
1. If
you have a companion, please invite him/her to sit in
the room.
2.
Sit down and face the mirror so that you head falls inside
the yellow box.
3.
Adjust the light inside and outside the room to achieve
the effect of "swapping faces".
Why?
You are actually sitting in
front of a transparent mirror, which can reflect light
and at the same time let light shine through. Which image
is eventually visible depends on the relative intensity
of the light sources on both sides of the mirror. When
one side of the mirror is brighter than the other, the
dimmer image will be eclipsed by the brighter one and
we would end up seeing the brighter image.
