我是在Glenn Randall的一篇Outdoor Photographer上的文章“The rarest light”第一次看到Gap Light這種提法,雖然這樣的光線很多人都見過。這篇文章把這光線的形成講的很清楚,我以前推薦過,這裏再推薦一次:
“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.”
