Can you see the optical illusion?.
Do you see a man walking by? And a guy taking pictures? The guy is actually photographing the metal mirror. The reflections give the illusion of people standing on the other side of the green short hedge. Even the green hedge is the reflection.
I took this shot at the 'Grounds For Sculpture', outdoor Sculpture Garden in Hamilton, NJ in 2014.
Camera: Canon SX130IS, handheld, standard setting image slightly cropped and resized to FAR requirement.
Enjoy!

Now an optical illusion
is when your eyes
play tricks on you.
It shows you things
that are not really there.

The old saying of only
half believe what you see
has more truth in it
than you would believe,
as we don?t always see things
the way they really are.
