The assumption that RGB values under shadow are proportional to RGB values under direct light does not hold for a chromatic shadow, which occurs, for example, in an outdoor scene when direct sunlight is blocked and other sources like diffused light scattered from sky or color bleeding among objects are present [26].
The control panels were exposed only to artificial light known as "sky glow," ambient humanmade light scattered in the sky and reflected back to the sea surface by the atmosphere.
There are clouds scudding through the immense blue sky, scattered terns wandering the waters with muted cries.
Hence the light of the setting Sun, which passes through a thick layer of atmosphere, has much more red than yellow or blue light, while light scattered from the sky contains much more blue than yellow or red light.
Once caricatured as "Helicopter Ben" for suggesting that cash scattered from the sky would cure deflation, the Federal Reserve's chairman is now widely accepted as a champion of low inflation.
Meanwhile, Thomson's flair for the breath-stopping image flourishes as mightily as ever, above all in the endless Arctic night where Kit can see "whole galaxies scattered across the sky, like cocaine on a smoked-glass table".
Surrounded by flat, scrubby, fenced-in land with telephone poles and low mountains in the distance, beneath a sky scattered with fair-weather clouds, the billboard projected a mythic vision of the great American frontier.
He and Nodland analyzed published observations of 160 radio-emitting galaxies scattered around the sky.
The researchers quickly noticed that the numbers of these galaxies varied widely in different "fields" scattered around the sky.
It's a mural of young black men, floating through a blue sky scattered with large cumulus clouds, wearing our era's streetwear: baggy blue jeans and oversized T-shirts, bomber jackets, Timbs, and Air Force 1s to perfectly match the backwards fitted caps on their heads.
While an atmospheric model of clouds as white surfaces and "Rayleigh scattering only" skies is sufficient to qualitatively discuss the results of this paper, we should note that quantitative modeling of light pollution requires much more attention to detail.
