On a recent windy and stormy day in Draper (Utah) I looked up while driving to see a small patch of blue sky peeking through the clouds. The color of the sky, which was so deeply blue, struck me as amazing. I have to imagine that the high wind had blown out much of the pollutants and created the extremely clear sky.
Very little post-production was done on this image other than a slight crop and a bit of contrast & sharpening. The blue color of the sky is just as it was photographed.
