White Magic




While yachting off the coast of Svalbard, Norway, photographer Paul Souders snapped this picture of a fogbow, a rainbow-like phenomenon that appears when sunlight is refracted—or bent—through fog droplets.

Water droplets in rain are large enough to act like prisms, bending sunlight to produce the well-defined bands of color in rainbows. But the much smaller droplets in fog scatter light more, producing almost white bows sometimes tinged with faint color.
