Début de la saison des pluies, au Pérou

A panorama of the mountains surrounding the Machu Picchu, covered in clouds as the rain season starts.
The picture is a false black and white. After adjusting the luminosity and contrasts, I converted the panorama in black and white, and then used the Color Balance adjustment in Photoshop to give it a more sepia tone, in order to accentuate the mood and the heaviness of the scene and the weather.
