4:14 p.m.

Ansel Adams was known for keeping unreliable dates for some of his best photographs.  Adams once said, "my unfortunate disregard for the dates of my negatives I have caused considerable dismay among photographic historians."




An honors physics class from Texas State University-San Marcos, titled "Astronomy in Art, History, and Literature," determined the exact moment (to the minute) Ansel Adams captured the famous "Moon and Half Dome."  December 28, 1960 at 4:14 PM.  Their work was published in the December 1994 Sky & Telescope magazine.  The PDF of this article can be found here


"Moon and Half Dome"

There was an "encore" on December 13, 1994 4:05 PM, which the Texas State students predicted.




This past November, on the 28th at 4:04 PM, there was another "celestial encore" for "Moon and Half Dome" in the sky east of Ahwahnee Meadow, Yosemite National Park.

  1. The Ansel Adams collection is housed at the University of Arizona and has a rotating display at the UofA center for creative photography. Luckily of for me, this is within biking distance of my house.

    This article is really cool. Thanks for sharing. The blog looks like it will be great, too.
