Yahoo! News: “US astronomers said they had pinpointed the moment and location when one of the most famous landscape pictures in photographic history was taken.
“Autumn Moon, the High Sierra from Glacier Point,” taken by Ansel Adams in Yosemite National Park, is a thrilling view of the American West, featuring a waxing Moon rising over dark, ice-tinged peaks.
But precisely when Adams took the iconic black-and-white picture has never been clear, and dates for it range from the mid to the late 1940s.
A team led by Donald Olson, a professor of physics and astronomy at Southwest Texas State University, claim that the mystery can be resolved.
Using lunar tables, topographic maps, weather records and astronomical software, backed by a scouting trip to Glacier Point itself, the researchers believe that Adams pressed the shutter on September 15, 1948 at 7:03 p.m. Pacific Daylight Time.”
