The blue hour is the period of twilight when the sun is at a significant depth below the horizon. During this time, the remaining sunlight takes on a mostly blue shade. This shade differs from the colour of the sky on a clear day, which is caused by Rayleigh scattering. Many artists value this period for the quality of the soft light. Photographers use blue hour for the tranquil mood it sets. The Giau Pass, in italian Passo di Giau, 2236 m. is a high mountain pass in the Dolomites in the province of Belluno in Italy. It connects Cortina d`Ampezzo with Colle Santa Lucia and Selva di Cadore. It is located at the center of a vast mountain pasture at the foot of Nuvolau and dell`Averau.
