I had scouted for the perfect spot to set up a tent next to an aspen tree with a mountain in the distance, then waited for a good evening shoot the milky way over the tent. Although the forecast was for clear dark skies, the clouds began to float in just as the first blue hour image was shot. But it was all clouds from then on. That only photo was what I came home with, but looked much better post processed with an art filter.
