Tropical South America

Creative rationale

Over the high Andes of Peru and Bolivia, where the extreme altitude creates an atmosphere of remarkable thinness, this location experiences the rarified conditions of mountain peaks above 4000 meters. The extraordinarily low sea-level pressure of 622.7 hPa reflects this alpine environment, while the cold temperature of 3.2°C and dry humidity of 27% capture the crisp, desert-like conditions of the altiplano. The minimal wind speed of 0.8 m/s suggests a moment of high-altitude stillness, which I interpret through wide, gentle undulations in Riley's early black-and-white optical vocabulary, with sparse line spacing reflecting the thin atmosphere and systematic geometric precision echoing the crystalline clarity of mountain air.
