In this photograph in The Readers’ Photos of La Vanguardia we can contemplate the twilight enveloping the surroundings of the Three Chimneys of Sant Adrià de Besòs from the sea, an image that brings us closer to the coastal skyline of Barcelonès Nord.
The image highlights the power of crepuscular rays, which, in atmospheric optics, are rays of sunlight that appear to radiate from a single point in the sky.
The name comes from its frequent appearances during twilight hours (sunrise and sunset), when the contrasts between light and darkness are the most obvious. Not in vain does crepuscular come from the Latin word crepusculum, which means “twilight.”
These rays flow through openings in clouds (especially stratocumulus) or between other objects. They are columns of sunlit air separated by dark regions of cloud shadow.
The photograph also highlights the flushed color of the sky, due to the candilazo, which is the red or orange color that is seen in the clouds illuminated by the sun’s rays, especially also at dawn and at dusk.
Sant Adrià, located at the mouth of the Besòs river, between Barcelona, ??Badalona and Santa Coloma de Gramanet, has as a major visual reference point the Tres Chimeneas, which was a conventional cycle thermoelectric installation.
