Here blue over white intersect as cloud shadows follow the curves of basins and ridges of the neve of the Fox Glacier. It seems a very ying/yang image with an extraordinary purity of almost duochromal hues. To bring the white out in the snow I overexposed by one stop and shot at a high speed to stop the scudding clouds.
Taken on Nikon F4. 50mm lens, Kodachrome 64, Aperture F8.
