Her enigmatic smile :)

What is a smile for you? Maybe most of us believe that a single smile expresses feelings and it is a very important attire that we should wear every time. But who would ever think that there is something in Mona Lisa's smile?

 

I believe that most of us know this very beautiful artwork of Leonardo da Vinci. It is Mona Lisa, smiling calmly. But, is she really smiling? Some say she is. Some say she isn't. Some believe that her enigmatic smile was just caused by small details. Leonardo da Vinci, they said, must have used a technique called sfumato that blur and shade outlines that results to a beautiful blending. Scientists, using a beam of high energy X-rays, determined how little strokes of brushes and glaze of paint had created the composition.

Upon seeing this artwork, we all see that Mona Lisa is smiling. The secret behind this is her smile is actually blurred in a low frequency pattern. Try not to look directly at her mouth; we can see that her mouth looks cheerful. But if you look at her smile directly, some parts may disappear, like an optical illusion. So with that, no one can never be sure if she's smiling or not.
