"You can never get a clear picture of the Emerald Buddha. It will always be blurred or something will happen." That is the legend surrounding the Emerald Buddha which is actually made out of jade. The power of the Buddha is so great that it refuses to be photographed. Taking photos of the Emerald Buddha in the temple is also banned. Well, as you can see, it's blurred. So I guess there is some validity to it.
The Emerald Buddha is only touched by the King of Thailand. He changes the clothes of the Buddha 3 times a year.
