Creative Rationale

Over the high Andes of Peru and Bolivia, this location sits at extreme altitude where the atmospheric pressure is extraordinarily low and temperatures remain frigid even in tropical latitudes. The minimal wind speed of 0.6 m/s from the northwest creates barely perceptible movement, translating into wide, gentle undulations that seem to breathe slowly across the composition. The extreme cold temperature anomaly and low pressure gradient call for Riley's classic black and white optical language with sparse, precisely calculated line spacing that creates subtle vibration effects rather than intense optical assault.
