The Last Supper in Detail

The highest definition photograph in existence is one of The Last Supper by Leonardo da Vinci.

The 16 billion pixel photograph of The Last Supper can be viewed online in all its glory, and allows viewers to enlarge and observe any portion of the painting down to as little as one millimetre square.

According to Wikipedia another photograph taken by the same group, that of the Gaudenzio Ferrari’s Vita di Cristo, was also at one point the largest photograph in the world at 6.8 billion pixels.
