Yuka says it’s because I have light-colored (green) eyes, but for whatever reason, I find glaring sunlight very oppressive, especially during the morning commute, with the sun just on the horizon and always in my face, slamming, boring into me. The southern haze is an all-subsuming intensity, light without color.
A cloudy sky can tame the sun’s tyranny, allowing all under its dominion to retain its natural shade. Perhaps it’s merely because the graininess of the air is removed as a factor (just as nighttime dispels the opaqueness of the atmosphere and permits us to see the heavens); perhaps it’s that everything we see is bathed, not drowned, in the light that remains; yet the world appears more clearly.
Though I’m no photographer, maybe all I’m talking about is the difference between an overexposed and a properly-exposed picture. Mellower light brings out subtlety, of hue and of texture. It makes our surroundings seem softer, more whole, and more interesting. I don’t think I’m exactly echoing Tanizaki’s In Praise of Shadows, for he loved darkness for its capacity to conceal, and I, for its capacity to reveal. A better example from art would be Closely Watched Trains, a dark, black and white film, whose visual elements seem almost glowing, almost touchable.
Overcast itself can be beautifully marbled and inlaid, converting the overexposed world to a vast hall with an ornate ceiling. Like a soft, familiar blanket, it provides cover and comfort.
This old painting, from my parents’ house, perhaps illustrates what I’m trying to say about the glowing richness of subdued light.
It’s so hospitable and friendly (“lovely, dark, and deep”?). Harsh sunlight would wash it all away.
