However, despite Leonardo’s incredible annotations in many other works and inventions, he never really explained why he achieved the effect of the “smoothing” effect, which made the Mona Lisa Painting has almost a three-dimensional effect.
The basic problem with the halo method is how to connect the shadows and lines together in an imperceptible way. “Mona Lisa” is a paint of Leonardo da Vinci on a piece of Italian poplar bark, dating back to 1503 – 1506 to the time when Leonardo da Vinci (1452-1519) came to an end.
Some areas of the “Mona Lisa” face may have 30 layers thick on top, although the paint layer is incredibly thin. There is extraordinary consistency in the painting, which shows that Leonardo da Vinci may have completed this legendary masterpiece for many years. The exact length of time has not been conclusive.
