Winter
Twilight Sky, Norfolk England. Reds are made by transmitted sunlight
depleted in blues and greens by scattering. The blue sky is seen by
the light it itself scatters. The combination of skylight with direct
sunlight, reflections and absorption by clouds and the ground add
yet more variety. Contrast between adjacent complementary colours
makes some stronger than they really are. Measure
the seemingly intense greens in this unretouched picture - they are
mostly subdued gold and olive hues.
November 30th 1999, sun 3° below
the horizon.
