Creative Rationale

Over the high Andes of southern Peru and Bolivia, where the extreme altitude creates an otherworldly atmospheric environment with dramatically low pressure and frigid temperatures despite the tropical latitude. The minimal wind and moderate humidity suggest a still, crystalline mountain air, while the complete absence of precipitation and the cold temperature anomaly inspire translucent pools of cool cerulean and teal that seem to freeze mid-flow across the canvas. The steep pressure gradient creates dramatic diagonal flows of color that cascade like glacial meltwater, with the low humidity allowing for more opaque patches of luminous salmon and ochre to emerge through the cooler washes.
