Who took the blue sky and white clouds on the default desktop after windows XP installation? What is the origin?

The default desktop of Windows XP is Bliss. The photo was taken in Sonoma County, California, USA. The southern part of Sonoma Valley is near the former site of Clover Stornetta, a dairy company. The name of bliss comes from the rolling green hills, blue sky and rolling white clouds here. This picture was used by Microsoft as the desktop wallpaper of luna theme in XP. This photo was taken by professional photographer Charles O 'lear (from St. Helena, Napa County) for digital design company HighTurn. O 'lear also worked for Bill Gates' private photo storage company Cobis in Seattle, and he also produced photos of Napa Valley in the May 1979 issue of National Geographic magazine. At first, O'Rear's main energy was to take photos of the wine industry in Napa Valley, but at that time, there were no vines growing on the Bliss Mountain in the late 1990s. This photo was taken by a hand-held large-format camera on the side of12/1highway.
