The photograph was taken last week from Glacier Point in Yosemite National Park at around 8:00pm. The setting sun illuminated Half Dome and Clouds Rest in the background. The setting sun also provided the natural yellow/orange color on the granite. This was taken using a 100-400mm zoom lens with the lens set at 100mm. It was very peaceful and was a joy to watch the sun light move up the face of Half Dome.
