Tropical South America 15s 70w

Creative Rationale

Over the high Altiplano of Bolivia and Peru, where the thin air creates extreme atmospheric conditions, this piece captures the ethereal quality of a cold, dry morning at altitude. The extremely low temperature of 16.1 K (-257°C) and moderate humidity create a composition dominated by cool blues and violets that pool at the edges, while the gentle wind from the southwest suggests subtle directional flow. Following Sam Francis's approach to luminous negative space, the central area breathes with pale washes while more saturated color fields gather at the periphery, reflecting both the sparse atmospheric conditions and the mystical quality of this high-altitude landscape.
