Entrance of Cullalvera Cave in Ramales de la Victoria, Cantabria, Spain. It was taken in august 13th, 2014.
Wide-angle view of Strada della Forra (Road of the Gorge). As the name says, a scenic road crossing a narrow gorge nearby Lake Garda, in the north of Italy, nestled in the depths of a mountain, along the rift carved by the waters of the river Brasa. Diffused light coming from the top of the crevice, high, looming walls of rock, a low tunnel cutting through the mountain, a stone kerb. Palette based on yellow and rich earthy tones, with hints of green. High level of detail, natural rendition, realistic feel. Developed from RAW.
