Fracture

“Fracture”. Southern Sardinia. The stretch of rocky coast, on which stands the Pixinnì tower and the Punic quarry, is marked by large steps and deep crevices, through which the water flows incessantly. The feeling of being in an extraterrestrial landscape is amplified by the approach of a dense blanket of rain-laden clouds, which obscures the sky and makes one feel crushed between two powerful and impetuous natural elements.
This shot was taken during the last photographic trek with the students of La Bottega della Luce and, actually, the exposure time was interrupted at about 4 minutes because of the beginning of a strong downpour brought by those dark clouds. Two NiSi filters were used to take the long exposure: a 15-stop solid ND filter, plus a 3-stop graduated filter (rotated about 30 degrees counterclockwise from the horizon) to balance the dynamic range of the scene, containing in this way the bright lights in the upper left portion of the frame.
