Its has been very hot lately, so I did not try to go out to take photos of anything. However, going through my archives, I found some images of the Mesquite Flat Sand Dunes in Death Valley National Park. Using my new DxO software I reprocessed the raw files to get the following photos, taken at sunrise one day in October of 2012.
The second image was taken less than a minute after the first one, just as the morning sun forcefully broke through the clouds. It was the most spectacular sight I had ever witnessed.
