A vivid red sunset at Jokulsarlon in Iceland turned the water of the lagoon into wine. I was shooting here two days in a row. The first day was dull and overcast. The afternoon of the second day didn't look too promising either, but something happened for a few minutes - maybe the wind changed direction or something - and then the sky lit up in these blazing reds and golds. It was beautiful, but brief. The reds disappeared in minutes and were replaced by blues.
