I captured these crepuscular rays during my summer holidays in Isola d' Elba, the island in front of Tuscany, Italy. The scene I attended was stunning, as huge blue beams were spreading all over the sky.

Crepuscular rays, in atmospheric optics are rays of sunlight that appear to radiate from a single point in the sky. These rays, which stream through gaps in clouds or between other objects, are columns of sunlit air separated by darker cloud-shadowed regions. The name comes from their frequent occurrences during crepuscular hours (those around dawn and dusk), when the contrasts between light and dark are the most obvious.
