Rainbow in Iceland
Photo and caption by Anil Sud
Backlighting on this scene would intermittently render a beautiful rainbow in the mist of the waterfall. I had not recalled ever seeing a time exposure of a waterfall with an accompanying rainbow before. In order to render the water as a silky background, a strong ND was used to lengthen the exposure time to 1 minute and provide a smooth contrast to the brilliance and well defined rainbow in the foreground.
