我是在Glenn Randall的一篇Outdoor Photographer上的文章“The rarest light”第一次看到Gap Light这种提法,虽然这样的光线很多人都见过。这篇文章把这光线的形成讲的很清楚,我以前推荐过,这里再推荐一次:
“If the sun finds a gap between dense clouds and the horizon, however, the clouds block that bright, white light from the sky around the sun, and the result is some of the most spectacular light you'll ever see.”
